Seven PAN-001 mathematically cover the 6800 mm sweep. This does not yet mean that exactly seven should be ordered.

The calculation looks almost flawless:

6800 / 1010 = 6,73.

We round up — we get 7 modules.

Seven PAN-001 give:

7 × 1010 = 7070 mm.

Nominal excess:

7070 − 6800 = 270 mm.

If you look only at the calculator, the eighth panel seems obviously redundant. But a bar counter differs from a straight wall by two actual ends with R=120 mm. And here 270 mm cease to be just a "cutting allowance."

Before payment, four things need to be checked:

  • whether the selected material PAN-001 actually passes the specific R=120 mm without undesirable changes;

  • where the joints will be relative to the two radius ends and the main frontal zone of the counter;

  • do 270 mm allow maintaining a correct rhythm and both extreme endings after actual cutting;

  • is 6800 mm the clean unfolded surface length along the facing, not the approximate straight-line length of the body.

That is why in this article the first product is not the full-size PAN-001, but a sample OPAN-001 196×8×310 mm.

The manufacturer describes OPAN-001 as a compact demonstration module for evaluating texture, pattern, profile depth, and material. At the time of verification, the following are available:

OPAN-001 Size Price
MDF 196×8×310 mm 540 ₽
Beech 196×8×310 mm 940 ₽
Oak 196×8×310 mm 1 490 ₽

The full-size PAN-001 has a flexible fabric base; the card directly indicates the ability to face straight and curved surfaces. But there is no separate published technical standard like "minimum guaranteed radius = 120 mm" in the card. Therefore, R=120 mm in our project cannot be considered automatically confirmed only by the general word "flexible."

The cheapest way to eliminate this risk is to physically buying a sample OPAN-001 use exactly the material planned for the stand and apply it to the already manufactured end.

After a successful radius check, a layout of seven full-size PAN-001 1010×8×950 mm is built. And only if this layout does not fit the actual parts, joints, and two beautiful endings into 7070 mm of original width, an argument for an eighth module appears.

Thus, the article answers two related but different questions:

  1. OPAN-001 confirms that the selected material is generally suitable for the specific R=120 mm.

  2. The cutting map confirms whether seven PAN-001 units are enough or an eighth is really needed.

If both checks pass, you can buy wall slat panels no longer 'with a margin percentage', but with a clear specification of the specific rack.

Sample of the slat panel OPAN-001 196×8×310 mm: what exactly we buy for the rack test

OPAN-001 does not replace the full-size PAN-001. Its task is much narrower: to provide a physical piece of the same geometric idea that can be brought to the manufactured body and checked where the drawing no longer answers all questions.

OPAN-001 made of MDF

Size — 196×8×310 mm.

Price at the time of check — 540 ₽.

An MDF sample is logical if the main batch of PAN-001 will also be made of MDF and will be painted with an opaque coating.

On the sample you can check:

  • real thickness and relief;

  • behavior of the flexible base on the radius;

  • how much the visual pitch of the slats changes when bending;

  • what the transition “straight → R=120 → straight” looks like;

  • surface quality for future finishing.

Our factory also produces:

Beech sample OPAN-001

Price — 940 ₽.

Beech is needed not as a more expensive version of the MDF test, but as a physical sample of a different material.

If the full-size batch is planned to be made of beech, it is advisable to test beech specifically. The flexibility of the entire panel is created by the fabric base and spaced apart slats, but the solid part of the slats remains natural wood. It is impossible to prove the behavior of beech on a tight actual radius just by the fact that the MDF sample visually fit on the same body.

Oak OPAN-001

Price — 1,490 ₽.

For an oak bar counter, this is a particularly rational purchase. Seven short oak PAN-001 1010×8×950 mm at the current price cost:

7 × 26 930 = 188 510 ₽.

Eight:

8 × 26 930 = 215 440 ₽.

Against this backdrop, the oak sample for 1,490 ₽ costs less than one percent of the seven-module batch and allows you to check the critical R=120 mm before the main payment.

Why the size 196×8×310 mm is sufficient for a local radius check

It is sufficient not for “certifying the entire counter,” but for a local answer:

  • whether the selected material fits the actual arc;

  • how the fabric base behaves;

  • how the gaps open up;

  • whether there is a visually unpleasant kink;

  • how the surface looks at the top of the tightest section.

The sample can be applied sequentially:

  1. at the beginning of the radius;

  2. closer to the top of the arc;

  3. at the very top;

  4. at the end of the radius;

  5. at the transition back to the straight line.

Thus, one compact module checks several characteristic zones.

What the small OPAN-001 fundamentally does not show

It does not prove:

  • that seven full-size modules will perfectly fit into 6800 mm;

  • that the joints will be invisible;

  • that both sides of the rack have the same actual geometry;

  • that the entire batch of oak will match in pattern;

  • that the specific adhesive and fasteners work throughout the entire site;

  • that 950 mm is exactly sufficient in height at every point;

  • that the edge cut will turn out beautiful at both ends.

That is, OPAN-001 is a control of material and local geometry, not a reduced copy of the entire project.

Flexible slat panel PAN-001 and radius R=120 mm: what cannot be decided based only on the product description

The PAN-001 card does indeed confirm the flexible fabric base and the ability to work on curved surfaces. The semicircular beads are attached to the fabric; individual modules can be joined into a single decorative covering.

This is good initial information.

But the phrase "suitable for curved surfaces" does not automatically answer the question:

"How will a specific oak, beech, or MDF module behave on the finished end with R=120 mm of this particular post?"

What to check on the actual radius

Fit of the base.
The fabric should follow the surface without unwanted creases or local detachment in the layout.

Changes in gaps between slats.
On the outer surface of the bend, visual intervals may be perceived differently.

Outer edge.
You need to see how the outermost slat looks at the transition from the straight section to the arc.

Behavior of the selected material.
MDF, beech, and oak should be considered different product variants.

chiaroscuro.
At R=120, each slat changes orientation relative to the luminaire faster than at a larger radius.

Transition back to the straight line.
Sometimes it's not the arc's apex, but specifically the exit from it that looks weaker.

Why we can't promise "PAN-001 is guaranteed to fit R=120"

Because the specific minimum radius is not published in the product card.

Expert text should not turn general flexibility into a fabricated engineering guarantee.

The correct wording is:

PAN-001 is designed for curved surfaces; the specific R=120 mm for the chosen material is confirmed by physically fitting OPAN-001 on a manufactured stand.

How to apply OPAN-001 to a finished end with R=120 mm before the main purchase

The main advantage of our scenario is that the stand is already manufactured.

No need to check the radius on a paper template if a real surface exists.

Check on the manufactured stand

The design R=120 mm could have changed slightly after:

  • manufacturing of the body;

  • puttying;

  • leveling;

  • final preparation.

Therefore, the control object is a finished or as close to finished surface as possible, not just CAD.

Check several heights

The bar stand may have a slight variation in radius or flatness along its height.

Apply the sample:

  • at the bottom;

  • in the middle;

  • Closer to the top.

If the behavior is the same, confidence is higher.

Check the start of the radius

This is where the straight surface begins to change direction.

Need to see if there is a visual step.

Check the top

This is the tightest zone in terms of curvature.

Check the exit to the straight

The second transition should look as smooth as the first.

Take photos from the side and from above

A frontal shot often hides the reveal of gaps.

From above, it's better visible:

  • the actual arc;

  • fit;

  • the line of battens;

  • Symmetry.

OPAN-001 from MDF or wood: why the radius should be checked in the exact material you will order

The most dangerous saving is to buy the cheapest MDF sample for 540 ₽, see that it fits R=120 mm, and then order an oak batch for almost 190 thousand ₽ without an oak test.

These are different product variants.

MDF OPAN-001 for painting

If the main batch is MDF, the logic is consistent:

OPAN-001 MDF → check R=120 → full-size PAN-001 MDF.

If after the test a decision is made buy MDF slat panelsit can already be considered 7/8 modules.

Oak OPAN-001 for transparent finish

If the rack must retain its natural texture, a physical oak sample simultaneously checks:

  • radius;

  • drawing;

  • tone;

  • reaction to side light;

  • future transparent finish.

After that, it is logical buy wooden slat panels already in oak.

Beech OPAN-001

Beech is a separate natural version.

If the project will be tinted or painted over wood, the sample helps evaluate not only the geometry, but also the real material.

Slat panel PAN-001 1010×8×950 mm: how many modules to order for a 6800 mm layout

Now we move on to the main purchase.

The article assumes that 6800 mm is the already unfolded length of the decorative surface, including both radius sections.

This is an important condition.

If 6800 mm is just the linear length of the stand according to the plan, and the arcs are not yet included, the calculation of 7 modules cannot be used.

Mathematical minimum

6800 / 1010 ≈ 6,73.

Therefore:

a minimum of 7 original PAN-001.

What seven give

7 × 1010 = 7070 mm.

Nominal excess

7070 − 6800 = 270 mm.

Why this is a good start

The excess is approximately:

270 / 6800 × 100 ≈ 3.97% of the net unfolded length.

But this ~4% is not a "margin per standard." It is simply the arithmetic difference between seven modules and the length of the object.

Why this percentage by itself doesn't decide anything

Because you can't glue all 270 mm into one convenient place.

In a real map, part will be lost:

  • at the beginning;

  • at the end;

  • for the pattern phase;

  • for precise seams;

  • for possible trimming of the damaged factory edge.

And only the map shows whether there is a real surplus after all operations.

Why 270 mm of remainder doesn't yet prove that the eighth PAN-001 is not needed

Seven modules is the mathematical minimum. A work order is confirmed only after specific parts for a specific rack can be assembled from 7070 mm.

Rack pattern phase

PAN-001 consists of repeating semi-circular glazing beads on a flexible fabric base.

When trimming longitudinally, the edge should not look accidentally torn.

If the mathematical cutting line passes through a visually inconvenient part of the rhythm, it may need to be shifted.

Each such shift consumes part of the 270 mm.

Location of the first cut

One edge of the rack may be more visible to the visitor than the other.

Then you cannot automatically use the entire allowance on the "technical" side if it breaks the main visible edge.

Location of the last cut

A mistake at the start shows up at the end.

If the first six modules are laid out without a common map, the seventh may end up with a too narrow or visually poor piece.

Two radius transitions

At each R=120 mm, you need not only to cover the length but also to maintain a readable rhythm.

If the joint falls on the tightest part of the arc, it may need to be moved to a straight section.

Damaged or inconvenient edge

In real production, the edge may require technological trimming.

The article does not prescribe universal 3, 5, or 10 mm. This is decided based on the actual part.

But the very fact of possible adjustment means that the "270 mm of margin" cannot be considered completely free.

The need to preserve a whole outer rail

If the designer requires finishing both sides of the post with a single visual element, the cutting layout may become more rigid.

Geometry of the actual body

Two ends with the same design R=120 mm may have slight actual differences after manufacturing.

Therefore, seven PAN-001 units are sufficient only when the actual seven modules are laid out on the actual post, not when the calculator shows 6.73.

How to understand whether an eighth PAN-001 is needed without a safety margin percentage

Instead of "let's add another 10%," you need to create a 6800 mm layout and place seven original strips of 1010 mm on it.

Step 1. Fix the clean layout

Measurement should be taken along the surface of the cladding.

Not along the axis of the post.

Not along the straight chord of the radius.

Not by the length of the countertop, if its overhang differs.

Step 2. Apply two R=120 mm

On the development, the following are marked:

  • the start of the first radius;

  • its apex/central zone;

  • the end;

  • the second radius similarly.

Step 3. Mark visible zones

Where is the visitor located?

Which end is most visible?

Is there a technical side?

Step 4. Apply desired joints

It is not necessary on every 1010 mm boundary.

Panels can be trimmed and redistributed if the actual structure allows it.

Step 5. Check edge endings

Both edges should be visually acceptable.

Step 6. Calculate leftovers for each original module

Only after this can you see if seven are enough.

Slat panel PAN-001 on two radius ends: where to start the layout

There are three strong approaches. Each has its own logic.

From the central axis of the post

Suitable if the front part is the main view.

The layout is built symmetrically to the left and right.

Pros:

  • The main facade gets controlled symmetry;

  • Both ends become a consequence of one central system.

Cons:

  • The extreme remainders may turn out unequal in convenience;

  • Both R=120 mm can "catch" different phases of the pattern.

From the most visible end

If one radius faces directly into the hall or entrance, it can be made the starting control point.

Pros:

  • The best edge and transition get priority.

Cons:

  • The opposite end gets everything left after the long sweep.

This scheme cannot be applied without preliminary verification of the end.

From the central straight section with a symmetrical transition to the radii

Often the calmest option for a bar counter.

The main rhythm is formed on the long straight zone.

Then both radii are checked against it.

If minor adjustments are required for the two ends, they are distributed along less noticeable straight sections.

Where the PAN-001 joint should be located on the bar counter

A joint is not a defect. PAN-001 is modular.

But the joint has good and bad locations.

Bad location: the top of the most visible radius

On the arc, the plane constantly changes direction.

Any vertical joint line receives additional shading and may read more strongly.

Bad location: bright side light

LED or directional light emphasizes the transition.

Bad location: central frontal point

If a visitor looks directly at the joint from several meters away, it becomes part of the composition.

Sometimes this is acceptable, but it must be intentional.

Bad location: high-contact zone

Staff or guests may regularly brush against the area.

The joint does not have to be weak, but for a high-traffic zone, a seamless visual surface is more convenient.

More convenient location: straight section

On a straight line it's easier to control:

  • rhythm alignment;

  • verticality;

  • clamp;

  • Light.

More convenient location: less visible end face

If the stand has a technical side, some joints can be moved there.

Can the PAN-001 joint be placed on the straight section instead of the radius

Yes, and for R=120 mm this is often more logical as a design priority.

But you need to check whether the length of the individual part is sufficient for the radius and adjacent transitions to run as one continuous strip.

Radius as a single part

Pros:

  • no joint in the zone of maximum curvature;

  • the drawing passes the arc continuously.

Cons:

  • the requirement for segment length grows;

  • the map of seven modules becomes less flexible.

Joint on the radius

May be acceptable if:

  • it falls into a calm phase;

  • the sample confirms the fit;

  • the light does not emphasize the line;

  • the installer is confident in repeatability.

But "can" does not equal "better".

Joint on the invisible side

A very strong solution if the rack geometry really has a back side.

But there is no need to move all joints into one small area and create a chaotic grid there.

PAN-001 1010×8×950 mm and rack body: check the vertical dimension before ordering

The short 950 mm format is convenient for a bar counter if the finished cladding height is less than this value.

The plan gives a guideline of 900–930 mm.

If the finished height is 920 mm

Nominal allowance:

950 − 920 = 30 mm.

This is convenient for fitting.

If the height is 930 mm

remains:

20 mm.

If the height is 945 mm

Only remains:

5 mm.

If at one point it is 955 mm

A short PAN-001 as a single piece is no longer sufficient in height.

Why measuring more than once is necessary

For a long post of 6.8 m, the following are possible:

  • floor slope;

  • tabletop deviation;

  • different height of the plinth/body;

  • local adjustment of the bottom.

Several control heights need to be taken across the entire layout.

What to consider the correct height of PAN-001 on the rack

It is not necessary to close the gap from the floor to the lower plane of the tabletop if the project provides for:

  • base;

  • metal bottom strip;

  • top belt;

  • shadow gap.

So, 950 mm is compared with the actual decorative zone, not with the total height of the rack.

Sample OPAN-001 and side light: why the profile looks different on the radius

On the straight section, all slats face the light fixture approximately the same way.

At R=120 mm, their local orientation changes quickly.

As a result, on one arc a sequence may occur:

  • light edge;

  • the average tone;

  • dark zone;

  • light again.

For MDF under enamel, this is created by shape.

For oak/beech, natural texture is added.

Check during the day

Natural light shows the overall relief.

Check under ceiling light

You can see how the slats read in the normal mode of the establishment.

Check with LED backlight

If light passes along the countertop or plinth, it can strongly emphasize the radius.

View from the visitor's side

Main commercial facade.

View from the staff side

Technical joints, access, and wear may be more important there.

MDF PAN-001 or oak wood slat panel: which material to check with sample OPAN-001

The choice of material affects both the price of 7/8 modules and the meaning of the sample.

The current card PAN-001 1010×8×950 mm shows:

Execution Price per unit 7 modules 8 modules
MDF "Prestige" 9 700 ₽ 67 900 ₽ 77 600 ₽
Primed MDF 15 810 ₽ 110 670 ₽ 126 480 ₽
Beech 16 800 ₽ 117 600 ₽ 134 400 ₽
Oak 26 930 ₽ 188 510 ₽ 215 440 ₽

Prices are indicated at the time of verification.

MDF (740–760 kg/m³, emission class E1/E0) provides ideal geometry, uniformity, and better base for enamel: high adhesion, smooth surface, absence of knots and cracks.

A strong option if the rack is painted in a single corporate/interior color.

The manufacturer's card separately describes the preparation of MDF for enamel and recommends priming before painting.

Primed MDF

More expensive, but part of the preparation is already included in the product configuration.

The difference on seven modules:

110 670 − 67 900 = 42 770 ₽.

This amount should be compared with the actual painting process.

Beech

Natural wood with a different texture character.

Tinting, transparent finish, or painting according to the project is possible.

Oak

The most expensive of the short options in the current card.

On seven panels, the surcharge for the eighth is 26,930 ₽.

Therefore, the oak OPAN-001 for 1,490 ₽ is a particularly reasonable preliminary check.

Why the rack material and the sample material must match

The MDF check answers the question:

"how the MDF version behaves."

It does not turn oak into MDF.

Even if the geometry of the glazing beads matches, natural wood:

  • has a different structure;

  • reacts to finishing differently;

  • may visually perceive a tight radius differently.

For an expensive main batch, saving on the correct sample is not justified.

Buy slat panels right away or first spend one order on OPAN-001

On a finished rack, the cost of a mistake is tens of times higher than the price of a sample.

Therefore, it is convenient to split the solution into two scenarios.

The main PAN-001 can be ordered right away if

  • the same material has already been used on a real R=120 mm;

  • the contractor has worked with PAN-001 in similar geometry;

  • the actual rack has been measured;

  • the joint locations are marked;

  • the map of seven modules already exists;

  • the finish has been approved on a physical sample.

In that case, OPAN-001 may not be a separate "test for the sake of testing," but only a control color reference.

First, OPAN-001, if

  • R=120 mm is new for the project;

  • the material PAN-001 has not yet been used on such a tight end face;

  • the stand is already manufactured and reworking it is expensive;

  • oak or beech is being ordered;

  • the main order is expensive;

  • the side light is strong;

  • the contractor doubts the visual phase of the relief.

Then Order a sample of slatted panel OPAN-001 — this is not a project delay, but a way to remove uncertainty before purchasing the main batch.

How much does the “seven or eight” mistake cost on different materials

The price of the eighth module equals the price of one short PAN-001:

  • MDF — 9,700 ₽;

  • primed MDF — 15,810 ₽;

  • beech — 16,800 ₽;

  • oak — 26,930 ₽.

If the eighth panel later remains intact and is useful elsewhere, it is not a complete waste.

If it is needed only as insurance against poorly planned cutting, it is an expensive way to replace a drawing.

Oak: a particularly sensitive choice

Seven — 188,510 ₽.

Eight — 215,440 ₽.

Difference — 26,930 ₽.

Oak OPAN-001 — 1,490 ₽.

That is, a physical preliminary check costs about 18 times less than one extra full-size oak module.

Beech

Seven — 117,600 ₽.

Eight — 134,400 ₽.

Difference — 16,800 ₽.

Beech sample — 940 ₽.

MDF (740–760 kg/m³, emission class E1/E0) provides ideal geometry, uniformity, and better base for enamel: high adhesion, smooth surface, absence of knots and cracks.

Seven — 67,900 ₽.

Eight — 77,600 ₽.

The difference is 9,700 ₽.

MDF sample — 540 ₽.

In all three cases, the sample is significantly cheaper than the eighth module, but its function is different: it checks the radius and material, not solving the cutting layout for the installer.

Cost of slat panels: when the eighth module is a useful reserve, and when it's an unnecessary overpayment

Requests about the cost of slat panels often lead to a simple comparison of "7 is cheaper than 8." For a bar counter, this is not enough.

The eighth PAN-001 is justified if the map of seven doesn't add up

For example:

  • both beautiful endings require additional cuts;

  • the joint needs to be moved away from R=120 mm;

  • one module must pass the radius continuously;

  • the actual unfolded length after the final measurement exceeds 6800 mm;

  • part of the original edge is unsuitable.

The eighth may be a useful service reserve.

For a commercial property, this is separate logic.

The bar counter receives:

  • shoe kicks;

  • staff contact;

  • cleaning;

  • equipment movement.

If PAN-001 is installed so that the local module can be replaced, a full spare from the same finishing batch may be valuable.

But this should be called a repair reserve, not a "cutting allowance."

The eighth is an overpayment if seven are already laid out.

If all finishing parts fit within 7070 mm, the joints are approved, the edges are good, and a service reserve is not needed, an additional PAN-001 adds no value.

How to create a cutting map for seven PAN-001 before order payment

Need a simple list.

Source PAN Section Net length Radius/straight We cut off Remainder
№1 left end ___ R=120 ___ ___
№2 left transition ___ radius/straight ___ ___
№3 Facade ___ Straight ___ ___
№4 facade center ___ Straight ___ ___
№5 Facade ___ Straight ___ ___
№6 right transition ___ straight/radius ___ ___
№7 right end ___ R=120 ___ ___

What should match at the bottom of the table

Sum of clean parts:

6800 mm.

Sum of original width:

7070 mm.

Sum of all trims and leftovers:

270 mm.

If the arithmetic doesn't add up, the map is incomplete.

Why the table should not automatically have seven parts of 971–972 mm

PAN-001 is the source module, not a mandatory finished section.

Finished parts may have different widths if needed for joints and radii.

Why you need to label radius/straight

Because two pieces of the same length are not equivalent.

One may be perfect for a straight line, but inconvenient at R=120 due to the joint line or edge orientation.

Example of a map that looks mathematically correct but is bad in practice

Suppose the installer decides:

  • leave the first six panels at 1010 mm;

  • cut the seventh to 740 mm.

Sum:

6 × 1010 + 740 = 6800 mm.

The arithmetic is perfect.

But the last piece gets the entire remaining 270 mm on one end.

If the right end is the main visible radius, that's where the extreme trim appears and, possibly, an awkward pattern phase.

What can be done better

Distribute the trims across two or several less noticeable zones.

For example, conditionally remove part from the left and part from the right.

But the specific numbers should be determined by the actual rhythm, not by a beautiful symmetry of "135 mm each."

Why the scheme "135 mm from both ends" is also not a ready-made recipe

Pure arithmetic:

270 / 2 = 135 mm.

It seems that what can be done is:

875 + 1010×5 + 875 = 6800 mm.

Let's check:

875×2 = 1750;

1010×5 = 5050;

1750+5050 = 6800.

Geometrically, the scheme is beautiful.

But the 875 mm lines can:

  • fall into different phases of the pattern;

  • give a bad ending;

  • turn out to be inconvenient on two R=120.

Therefore, 875+…+875 is a good layout sketch, not a final cut.

How to use 270 mm not as random waste, but as a phasing resource

It is these 270 mm that allow you to slightly move the joints.

Allowed:

  • trim the first module;

  • change the length of the second;

  • move the joint away from the radius vertex;

  • keep the last edge more intact.

The more accurately the rack is marked, the more useful this small resource is.

Why the percentage of allowance does not replace a map of specific parts

7 panels give about 4% nominal excess.

8 — already:

8080 − 6800 = 1280 mm of excess.

In percentage:

1280 / 6800 × 100 ≈ 18,8%.

That is, the transition from 7 to 8 sharply increases the purchase allowance.

This doesn't mean 8 is bad. It means the eighth module must have a specific function:

  • cover an impossible cut;

  • become a repair reserve;

  • go to another object/facade.

If the actual layout turns out to be 6870 mm

Seven PAN-001 give 7070.

Remainder:

7070 − 6870 = 200 mm.

The margin decreases.

If the layout is 6950 mm

remains:

120 mm.

If 7020 mm

remains:

50 mm.

If 7080 mm

Seven is already physically insufficient.

Key takeaway

The phrase "rack 6.8 m" is not enough.

Before payment, a final unfolded layout with accuracy corresponding to the actual installation is needed.

How to measure the unfolded length of a rack with two R=120 mm

If the rack is already manufactured, the most practical way is to measure along the surface of the future cladding, following both radii.

Depending on the condition of the body, a flexible measuring tape or a prepared template can be used.

What not to do

Do not add up:

  • straight facade;

  • "approximate width of two ends";

  • visually estimated arcs.

Why the radius complicates the ruler

A straight tape measure between two points measures the chord, but the cladding goes along the arc.

If 6800 mm has already been obtained from the development

Re-check after final preparation of the hull.

Can the arc length be calculated using R=120 mm

Only if the central angle of each arc is known.

Formula:

L_arc = R × θ, where θ is the angle in radians.

But in the article's plan, the angle is not specified.

One cannot assume that each end is a quarter circle, semicircle, or any other arc.

Therefore, R=120 alone is insufficient for recalculating the total length.

This is an important example of why actual unfolding is stronger than a beautiful geometric guess.

Radius counter and daily contact: material is chosen not only by bending

A bar counter is not a decorative column that no one touches.

The lower cladding works in the zone:

  • visitors' footwear;

  • cleaning equipment;

  • carts;

  • accidental bag impacts;

  • legs of bar stools;

  • regular wet cleaning.

Therefore, a successful OPAN-001 test at R=120 mm is only the first filter.

After that, the material is evaluated based on its performance.

MDF for opaque painting

Plus, you can get a single corporate or interior color.

If the rack housing, adjacent panels, and furniture are painted the same, PAN-001 looks like part of the architecture.

But the finish must match the area of constant contact.

The manufacturer specifies polyurethane and acrylic enamels as wear-resistant options for furniture applications, and acrylic/latex water-based compositions for interiors. The specific system is chosen by the finisher based on actual use.

Oak under a transparent finish

The strong point is the natural texture.

On the fiber radius, light and shadow change together, so the stand can look particularly expressive.

But in the bar area, the natural surface must have a consistent protective finish.

Beech

A calmer texture, natural wood, the possibility of tinting or painting.

It can be a rational intermediate option between MDF and oak.

What to check OPAN-001 not only at R=120, but also in the impact-contact zone

The sample can be used as a mini-test of the finish.

Check 1. Color

Under daylight and artificial light.

Check 2. Gloss

Matte and semi-matte relief look different.

Check 3. Tactility

The visitor can touch the counter with their foot or hand.

Check 4. Cleaning

It is convenient to check the compatibility of the agreed finish with the cleaning method that will actually be used on a separate sample.

What not to do

Do not invent a "household chemical test" without recommendations from the coating manufacturer.

First, the finish system and acceptable care are approved.

Do not discard OPAN-001 after the check: make it the project's reference standard.

After the sample has passed R=120 mm and the material is approved, it ceases to be just a demonstration piece.

It can be turned into a physical passport of the counter.

On the back side or on the label, record:

  • OPAN-001;

  • material;

  • project;

  • bar counter;

  • R=120 checked;

  • date;

  • color/stain;

  • varnish/oil/enamel;

  • shine;

  • responsible for approval.

Why this is needed

The project goes through several people:

  • designer;

  • customer;

  • carpenter;

  • finisher;

  • installer;

  • operation.

Everyone may have their own idea of the phrase "that very oak."

A physical sample removes ambiguity.

General sample section

If the project compares several materials before the final choice, you can order STAVROS product samples and form a small physical library of the project.

When one OPAN-001 is not enough

If the client is really choosing between MDF, beech, and oak, one sample only covers one material.

Then it makes sense to take several OPAN-001.

Cost of three samples

540 + 940 + 1 490 = 2 970 ₽.

Against the backdrop of seven full-size panels even made of MDF:

67 900 ₽,

that's about:

2970 / 67900 × 100 ≈ 4,4%.

Against the backdrop of oak

How to decide where the first module should stand

A bar counter may not have a physical "beginning" for the visitor.

But there is a main viewpoint.

If the counter faces the hall frontally

The main facade gets priority.

If one end is visible from the entrance

Its edge can be made exemplary.

If both ends are equally noticeable

It is logical to build the layout symmetrically relative to the front.

How to use a paper layout at 1:10 scale

With a length of 6800 mm, the 1:10 scale gives:

680 mm.

One PAN-001 module:

101 mm.

The remainder of seven:

27 mm.

On the sheet, it is easy to move seven strips and see:

  • joints;

  • radii;

  • edges;

  • Light.

This is faster than discussing the layout only with numbers.

Why 1:10 is not enough for the final edge

It is needed for the composition.

The line of the specific cut is checked at a 1:1 scale on real PAN/OPAN.

What to do if the map of seven modules converges only with one ugly joint

There are three options.

Option 1. Shift the adjacent joints

Use the 270 mm part differently.

Option 2. Change the layout start

Sometimes moving the zero point solves the problem.

Option 3. Buy an eighth one

If the first two do not give a good result.

The eighth one here already has a proven function.

What to do if the card seven fits with a 40 mm margin

Mathematically, it is sufficient.

In practice, the margin is very small.

Need to check:

  • accuracy of the actual layout;

  • quality of factory edges;

  • installation trims.

If everything is confirmed, seven are possible.

If 6800 mm were rounded, the risk is high.

What to do if after the final measurement the length is 6815 mm

Seven give:

7070 − 6815 = 255 mm.

The difference is small.

But the map is recalculated.

Why can't we keep the old one

The position of the joints relative to the radii shifts.

If the post height is 900 mm

PAN-001 950 gives 50 mm of nominal allowance.

If 930 mm

20 mm.

If the height varies 915–928 mm

The short version still nominally covers all points, but the bottom/top trim line must account for the difference.

When the short PAN-001 950 mm is more convenient than the long 2400/2670

For a stand height of about 900–930 mm, the short SKU is close to the finished size.

Advantages:

  • less waste in height;

  • easier transportation;

  • lower risk of damage;

  • clearer map.

When a long panel can be more advantageous

If from one length you can get two or more full-fledged elements at different objects/zones.

But that is already a separate general cutting plan.

Why you cannot simply cut a long PAN-001 into two 950 pieces and count the savings

Need to compare:

  • the current price of the long SKU;

  • actual length;

  • relief orientation;

  • quality of both obtained ends;

  • remainder;

  • labor.

For one rack, the short 950 mm remains the most straightforward option.

Current availability: why material affects not only price

At the time of checking, the short PAN-001 1010×8×950 mm shows as follows:

  • MDF — 26 pcs. in St. Petersburg;

  • beech — 11 pcs.;

  • oak — 6 pcs.;

  • primed MDF — made to order.

For seven modules:

MDF (740–760 kg/m³, emission class E1/E0) provides ideal geometry, uniformity, and better base for enamel: high adhesion, smooth surface, absence of knots and cracks.

The displayed balance is sufficient.

26 − 7 = 19 pcs. remains nominally.

Beech

11 − 7 = 4 pcs.

For eight:

11 − 8 = 3 pcs.

Oak

The card shows only 6 pcs.

For seven, at least one is missing according to the current display.

For eight, two are missing.

What does this mean

The oak project needs to be approved before payment as a combination:

  • current free balance;

  • possible production;

  • deadline;

  • finishing of the entire batch.

The card indicates an average production time for custom orders of 5–10 days, but the specific readiness date for the required quantity must be confirmed by a manager.

Why the availability of OPAN-001 needs to be checked separately from PAN-001

Samples are now noticeably more available:

  • MDF OPAN-001 — 252 pcs in St. Petersburg;

  • oak — 49;

  • beech — 13.

This makes the testing stage organizationally simple.

But the availability of a sample does not mean the availability of seven/eight full-size panels.

What to send to the STAVROS manager to order PAN-001 after testing OPAN-001

A good request should not sound like:

"You need about seven panels per stand."

It should convey already made decisions.

Example:

PAN-001 / 1010×8×950 mm / material ___ / bar counter / finished sweep 6800 mm / two actual R=120 mm / OPAN-001 of the same material verified on a finished body / 7 working modules per cutting map / eighth module: yes/no, function ___ / cladding height ___ / joint scheme ___ / finish ___.

After such a check, you can order PAN-001 1010×8×950 mm in the confirmed quantity.

Why write "finished sweep" in the request

So that 6800 mm is not mistaken for an approximate tabletop length.

Why specify OPAN-001

The manager understands that R=120 has already been physically tested.

Why specify the function of the eighth module

If it is needed, it should be clear why:

  • cutting;

  • reserve;

  • another zone.

When the full-size PAN-001 is NOT yet needed to be ordered

R=120 exists only in the drawing

The housing is still being refined.

Physical testing is premature.

The stand is still being puttied

The actual surface of the radius is changing.

OPAN-001 is not attached

For the new material, an unconfirmed risk remains.

Material not selected

Cannot calculate price and finish.

6800 mm is approximate

Seven/eight are not defined.

Joints not marked

Nominal 270 mm proves nothing yet.

Cladding height not measured

950 mm may be insufficient at one point.

Finish not approved

Especially for oak and beech.

Bottom/top edge not resolved

Trim or metal belt can change the finished height.

When you can buy seven PAN-001

Seven is a strong option if the following conditions are met simultaneously:

  1. the finished sweep is indeed about 6800 mm and is fixed;

  2. OPAN-001 of the required material passes both R=120;

  3. the 950 mm height covers all control points;

  4. the map of seven modules is built;

  5. both extreme endings look normal;

  6. the joints are moved away from undesirable zones;

  7. after real trimming, a positive technological remainder remains;

  8. a full repair module is not needed.

When the eighth PAN-001 is justified

  1. the map of seven does not match;

  2. the actual layout has become larger;

  3. for beautiful endings, one has to sacrifice too much width;

  4. one joint needs to be moved away from the critical radius, and there is no other way;

  5. the object wants to keep the full repair module;

  6. the remainder of the eighth panel is planned for another real zone.

When the eighth PAN-001 is not needed

If it appears only because someone is used to adding "10%."

In our case:

7 → 8 is an increase in quantity by approximately:

1 / 7 × 100 ≈ 14.3% relative to the seven-module order.

According to the original layout, the excess increases from 270 to 1280 mm.

This is too noticeable a surcharge to make it without a map.

Errors when linking OPAN-001 → PAN-001 on a rack with R=120

Error 1. Ordering seven just because 6800/1010=6.73

Why it occurs: the calculator gives an obvious answer.

Consequence: joints and edges do not fit into the real rhythm.

How to prevent: map of details before payment.

Mistake 2. Automatically order eight "with a reserve"

Why it occurs: fear of cutting.

Consequence: an extra full-size panel for 9,700–26,930 ₽.

Mistake 3. Check R=120 only with an MDF sample, then buy oak

Why it occurs: MDF is cheaper.

Consequence: behavior of the final material is not verified.

Mistake 4. Consider overall flexibility a guarantee of a specific minimum radius

Why it occurs: the card mentions curved surfaces.

Consequence: unconfirmed engineering confidence.

Error 5. Check OPAN-001 at only one point of the arc

Why it occurs: the sample is small.

Consequence: a bad transition to the straight line is skipped.

Error 6. Check only one of the two R=120

Why it occurs: according to the drawing, they are identical.

Consequence: actual asymmetry is detected during installation.

Error 7. Measure 6800 mm in a straight line, not along the surface

Why it occurs: a tape measure is simpler.

Consequence: the actual facing length is greater.

Error 8. Assume the shape of the arc based on one R=120

Why it occurs: you want to calculate the circumference.

Consequence: an unknown angle turns into a made-up number.

Error 9. Leave a joint at the top of the most visible radius without a reason

Why it occurs: the module ended exactly there.

Consequence: light highlights the seam.

Error 10. Remove all 270 mm from one end

Why it occurs: it is arithmetically simpler.

Consequence: one end gets a random edge.

Error 11. Divide 270/2 and consider 875+…+875 as a ready cut

Why it occurs: symmetry seems ideal.

Consequence: cut lines may not align with the pattern phase.

Error 12. Not measuring the post height by length

Why it occurs: the body “should be 920 mm.”

Consequence: at one point of the short panel, there is not enough.

Error 13. Painting the entire batch before testing the radius

Why it occurs: they want to speed up finishing.

Consequence: unsuitable material already has an expensive finish.

Error 14. Considering OPAN-001 a full check of all joints

Why it occurs: the sample passed the arc.

Consequence: problems with long layout remain.

Error 15. Do not store the approved sample

Why it occurs: after ordering, it seems unnecessary.

Consequence: the finisher and installer lose the physical reference.

Error 16. Order oak based on the current 6 pieces without confirming the seventh

Why it occurs: the card shows "in stock."

Consequence: the batch stops due to one panel.

Error 17. Consider 270 mm as one useful remainder

Why it occurs: total arithmetic.

Consequence: in the real map, it is distributed across several cuts.

Error 18. Use the repair eighth module as compensation for poor installation

Why does it occur: "there is a reserve."

Consequence: the reserve disappears before the object opens.

How to check the seven-module map for common sense

After the table, ask five questions:

  1. Where is the most visible joint?

  2. How does the left end finish?

  3. How does the right one finish?

  4. How many millimeters actually remain after all finishing parts?

  5. Can one cutting error be fixed without the eighth panel?

If the last answer is "no," the eighth module may be justified as an installation risk, but this decision is already made consciously.

Three practical layouts for the same 6800 mm sweep

The same total of 6800 mm can be assembled in different ways.

Scenario A. Main view — long front

Then the central straight part gets priority.

Logic:

  • several most integral modules go to the front;

  • joints are moved closer to transitions;

  • both radii pass as continuous sections where possible.

Plus — a calm facade.

Minus — radius parts may require more complex trimming.

Scenario B. One end — main

For example, it is visible from the entrance.

Then the first R=120 is made as cleanly as possible.

The rest of the cutting layout is built from it.

In this scenario, one must not forget to model the right edge in advance. Otherwise, the "ideal" first end consumes the entire 270 mm resource.

Scenario B. Both ends are equally important

Then a symmetrical idea is useful:

  • identical extreme sections;

  • central straight part;

  • equivalent radius transitions.

This is the most demanding option for the seven modules. If the rhythm of the two edges does not align, the eighth module may become a real necessity.

What remainder of seven PAN-001 should be considered normal after cutting

There is no universal number.

It's important not to "leave a minimum of X mm", but to understand the quality of the remaining material.

Useful remainder

May come in handy:

  • for finish testing;

  • for local repairs;

  • for a small furniture insert;

  • as a rhythm reference.

Technological waste

A short or inconvenient piece that cannot be used.

Installation reserve

A whole or sufficiently large fragment that can replace a real part.

Why 270 mm in total can turn into almost zero useful reserve

If they are distributed:

  • 35 mm;

  • 40 mm;

  • 60 mm;

  • 55 mm;

  • 80 mm,

no single piece may have practical value.

The sum remains 270 mm.

Usefulness — no.

If the object needs a repair reserve

There are two ways.

Save a large remainder of seven modules

Cheaper.

But it only works if the card allows obtaining a truly usable part.

Buy the eighth PAN-001 entirely

More expensive.

However, the full module is preserved:

1010×8×950 mm.

For a commercial facility, such a reserve is easier to label and store.

What to choose

Depends on:

  • service life;

  • the availability of future reordering;

  • material prices;

  • maintainability of the mounting system.

How to store the eighth panel if it was purchased as a spare

Do not leave unsigned.

Marking:

PAN-001 / 1010×8×950 / material ___ / bar counter ___ / finish ___ / batch ___ / spare.

If the panel is already finished, the packaging must protect the front surface.

If stored unfinished, a finishing specification should be nearby.

Why an oak spare is visually more valuable than an MDF spare

MDF for enamel can be painted later in an approved color.

Oak has a natural texture.

A reorder after years may differ more in pattern.

This does not mean that the eighth oak PAN-001 is mandatory. But the argument for a spare for a natural material is stronger.

How to make OPAN-001 part of finished rack acceptance

After installation, the reference sample can be applied to the straight section and compared:

  • color;

  • shine;

  • texture;

  • relief quality.

What this helps detect

  • incorrect shade;

  • different degree of matteness;

  • finish deviation.

What it does not help with

The sample is not a metrological instrument for the geometry of the entire rack.

What to check after installing PAN-001 on R=120

Transitions

Both zones "straight → radius" must be smooth.

Vertices of the two ends

Is there any local opening or fold.

Joints

Does the rhythm match.

Lower edge

Does the line wander in height.

Top edge

Are there any random gaps under the countertop.

Light

Check under the working lighting of the establishment.

Why acceptance should be done before the opening of the facility

After launch:

  • the rack is occupied by equipment;

  • operation is in progress;

  • access is more difficult;

  • local modification interferes with work.

What to do if after installation one R=120 visually differs from the second

First, determine the cause.

Do not automatically attribute it to a "wood feature."

Check:

  • the actual shape of the housing;

  • panel direction;

  • joint;

  • lighting;

  • finish.

How to order seven PAN-001 without an extra module

The final specification may look like this:

PAN-001 / 1010×8×950 mm / material ___ / 7 pcs. / finishing reamer 6800 mm / two R=120 mm / OPAN-001 of the same material verified / cutting map approved / joints ___ / cladding height ___ / finish ___ / eighth module not required per map.

This is much stronger than:

"7 panels, seems enough."

How to order eight PAN-001

If the eighth is needed:

PAN-001 / 1010×8×950 mm / 8 pcs. / 7 working + 1 repair reserve

Or:

8 pcs. / eighth module needed for cutting section ___.

The purpose must be written directly in the order.

Why the late CTA should lead to a specific product card

After all the checks, the user already knows:

  • model;

  • size;

  • material;

  • Quantity.

So, buy wall slatted panels as a category are useful for comparison, but the final action is a specific PAN-001.

Control matrix before payment of the main batch

To prevent the solution from falling apart into separate verbal agreements, it is useful to consolidate everything into one sheet before ordering.

Checkpoint Result
Finishing sweep of the rack ___ mm
Design radius of the left end R=120 mm
Actual left end checked by OPAN-001 Yes/No
Design radius of the right end R=120 mm
Actual right end face checked by OPAN-001 Yes/No
Sample material MDF / beech / oak
Main PAN-001 material same / different
Cladding height min ___ mm
Cladding height max ___ mm
Seven PAN-001 give 7070 мм
Nominal excess at 6800 270 мм
Map of seven modules converges Yes/No
Joint at main radius Yes/No
Extreme endings approved Yes/No
The eighth is needed for cutting Yes/No
The eighth is needed as a reserve Yes/No
Finish approved Yes/No
OPAN-001 saved as reference Yes/No

Why are there two separate rows about the eighth PAN-001 in the table

Because these are two different procurement reasons.

The eighth for cutting is consumed in production.

The eighth as a reserve remains intact after installation.

If these functions are mixed, the project may order eight, use all eight, and then mistakenly assume that a repair reserve exists at the site.

Why the sample material and main panel are recorded on separate lines

This immediately reveals the most unpleasant substitution: the MDF sample passed R=120, but unexpectedly oak was sent in the order.

If the materials differ, a separate justification or a repeated test is required.

Total price of preliminary verification and main procurement

Sometimes OPAN-001 is perceived as an additional small purchase that can be removed from the budget.

Let's compare the full path.

MDF: sample + seven PAN-001

540 + 67 900 = 68 440 ₽.

Beech

940 + 117 600 = 118 540 ₽.

Oak

1,490 + 188,510 = 190,000 ₽ exactly at current prices.

For the oak project, the physical verification of the critical radius increases the merchandise budget from 188,510 to 190,000 ₽, i.e., by less than one percent.

If after the test it turns out that the material is not suitable

The loss is limited to the sample and inspection time, not the entire full-size batch.

This is the economic rationale behind the sequence OPAN-001 → PAN-001.

What to do if OPAN-001 shows a beautiful radius, but the seven-module map still doesn't align

This is a normal result.

The sample only answered its own question: the material is visually capable of passing the actual end face during a test fitting.

What remains is a procurement question.

Option 1. Redistribute the joints

Shift the zero point and reuse the 270 mm.

Option 2. Change the position of one joint on a straight line

Sometimes that is enough.

Option 3. Buy an eighth PAN-001

If the first two paths worsen edges or radii.

It is important that the eighth module appears after proven necessity, not before the calculation.

What to do if seven modules converge, but the remainders are very small

This is not necessarily a problem.

If all finished parts are obtained, edges are good, and assembly risk is accepted, a useful repair remainder does not have to exist.

But for a commercial rack, you need to separately decide whether a service reserve is needed.

If a reserve is not needed

The order remains 7.

If needed

The order becomes 8, but the eighth module is marked as repair and does not participate in cutting without a separate decision.

Why a 6.8 m bar counter is a good example where the “reserve percentage” is misleading

With seven modules, the nominal excess is about 4%.

With eight, it is almost 19%.

No number by itself indicates which option is correct.

Correctness is determined by:

  • radii;

  • joints;

  • edges;

  • height;

  • operational policy.

Therefore, after checking, you can Buy slatted panels specifically by the map, not by the rule “add 10%”.

If two ends have one R=120 mm, but different arc lengths

The same radius does not mean the same unfolded length of the radius sections. The arc depends not only on R, but also on the rotation angle. Therefore, the left and right ends cannot be automatically considered mirror images just by the R=120 marking. On the finished post, each section is measured along the surface, and these actual lengths are transferred to the PAN-001 map. This is especially important if one end transitions into a short side panel, and the other into a longer one.

FAQ

What is the size of OPAN-001?

196×8×310 mm.

What materials is OPAN-001 produced from?

MDF, beech and oak.

How much does OPAN-001 cost?

At the time of checking: MDF 540 ₽, beech 940 ₽, oak 1,490 ₽.

What is OPAN-001 for?

For physical verification of texture, relief, material, finish, and local behavior on a real surface before the main order.

Can OPAN-001 be tested on R=120 mm?

Yes, specifically as a physical fitting of the specific material on the finished end. But this does not turn R=120 mm into a published factory minimum radius.

Does the sample guarantee the suitability of the entire post?

No. It checks the local section. Joints, total length, and height are checked separately.

Is it necessary to take a sample in the same material as PAN-001?

For the final decision, preferably yes. An MDF sample should not be the sole basis for an expensive oak batch.

What size is the short PAN-001?

1010×8×950 mm.

How many PAN-001 are needed for 6800 mm?

The mathematical minimum is 7.

How much do seven modules give?

7070 mm of original width.

What is the nominal remainder?

270 mm.

Why might seven not be enough in practice?

Due to the actual layout, relief phasing, trims, two radii, and requirements for beautiful edges.

When is the eighth PAN-001 needed?

When the map of seven does not align, or a separate full repair reserve is needed.

Where is it best to place the joints?

Usually it's easier on straight or less visible sections, but the final layout depends on the viewpoint and rhythm.

Can a joint be made on a radius?

This is not universally prohibited, but at R=120 it needs to be especially carefully checked for light, geometry, and installation.

How to check the height of 950 mm?

Measure the actual height of the decorative zone at several points along the entire stand.

What is better for the stand — MDF, beech, or oak?

It depends on the design, finish, budget, and usage. The material needs to be checked with physical OPAN-001.

How much do seven short PAN-001 MDF panels cost?

67,900 ₽ at the time of checking.

And eight?

77 600 ₽.

How much do seven oak PAN-001 cost?

188 510 ₽.

Eight oak ones?

215 440 ₽.

What to do if only six oak panels are shown in stock?

Coordinate the free balance with the manager and produce the missing quantity before starting the finishing.

Can 6800 mm be counted along the straight facade?

Only if it is already the actual surface development. Arcs cannot be replaced by chords.

Can the arc length be calculated using only R=120?

No. The central angle or the actual development is needed.

Where to buy OPAN-001?

In the OPAN-001 sample card.

Where to buy PAN-001?

After the test — in the PAN-001 card.

Where to compare different slat panels?

In the general category of flexible slat panels.

Conclusion

For the bar counter with a clean layout of 6800 mm, seven PAN-001 1010×8×950 mm are indeed the mathematical minimum:

7 × 1010 = 7070 mm.

Nominally, 270 mm remains.

But the decision of "seven or eight" cannot be made by a single division. Two ends with R=120 mm require checking the relief phase, joint locations, the start and end of arcs, both extreme endings, and the actual geometry of the body.

Therefore, the first step is not a full-size batch, but an OPAN-001 196×8×310 mm in the same material. The manufacturer confirms the flexible base of PAN-001 and its work on curved surfaces, but there is no separate guaranteed minimum R=120 mm in the specification. Physical fitting closes exactly this gap.

If OPAN-001 from the selected material easily passes both actual radii, then a map of seven full-size modules is built. Seven can be ordered when all real parts fit within 7070 mm, joints are in acceptable places, edges are neat, and a positive technological margin remains after trimming.

The eighth PAN-001 is not needed "just to take 10%". It is justified only if:

  • the map of seven does not match;

  • the finishing reamer has grown;

  • the joint needs to be moved away from the radius;

  • a beautiful ending requires additional material;

  • the object deliberately wants a full repair reserve.

At current prices, the cost of such a solution varies greatly: the eighth MDF module adds 9,700 ₽, beech — 16,800 ₽, oak — 26,930 ₽. Therefore, for expensive wood, a physical sample and a proper cutting map are especially beneficial.

The height needs to be checked separately. If the decorative zone is 900–930 mm, a PAN-001 with a length of 950 mm has a working nominal allowance. If at any point the cabinet exceeds 950 mm in height, the short format no longer solves the problem automatically.

Final sequence:

OPAN-001 of the required material → both R=120 → light and finish → finishing reamer 6800 → map of seven PAN-001 → joints → edges → leftovers → decision on the eighth → order.

After such a check, you can buy slatted panel PAN-001 in a quantity confirmed by the actual cabinet, not by a percentage of allowance.
