More than 20 years on the market
The company's success began in 2002, when two artists — Andrey Ragozin and Evgeny Tsapko — created a small creative workshop for producing wooden carved items. The masters' work was quickly noticed, and within a year they were invited to participate in the reconstruction of the Konstantinovskiy Palace in Strelna.
After the success of this project, the company focused on recreating palace interiors, furniture, church furnishings, and carved decorations in various artistic styles. They worked with cultural heritage sites: The Hermitage, the Alexandrovsky Palace, the Troitsko-Izmaylovsky Cathedral, the Sheremetyevsky Mansion, and many others.
The masters' task — and still is — to create wooden items with the highest level of detail and understanding of every element, based on impeccable knowledge of artistic laws and interior styles.

TR20 from the South Korean manufacturer Hi Wood is a universal decorative solution with ideal square proportions 20mm x 20mm and standard profile length of 2.0 meters. The product features a strict geometric shape, creating clear lines and perfect symmetry in interiors. Stavros Company, being an official Hi Wood partner in Russia, guarantees the authenticity of the product and compliance with all international standards for decorative elements quality.
Polystyrene moldingTR20 has unique technical parameters that make it a universal tool for various design tasks. The profile width and height are both 20 millimeters, creating an ideal square cross-section. This geometry ensures excellent visual prominence of the molding and allows its use both horizontally and vertically without altering its appearance.
Technical Specifications
wall molding polystyreneA square cross-section of 20x20 millimeters is the optimal size for most interior applications. The profile is sufficiently expressive to create noticeable decorative accents, yet does not overload the space. Ideal proportions make TR20 suitable for rooms of any size – from compact apartments to spacious cottages.
The standard 2.0-meter profile length is universal for transportation, storage, and installation in rooms of standard dimensions. This length allows working with the molding in residential and commercial spaces, minimizing the number of joints on straight sections. The weight of one profile is approximately 180 grams due to the use of lightweight high-density duro-polymer.
TR20 is produced from a special composite material – duro-polymer or phytopolymer. This is a modified polystyrene with a density of about 680 kg/m³, which significantly exceeds the density of ordinary expanded polystyrene and approaches the characteristics of polyurethane. The material is specifically developed for producing decorative elements with enhanced requirements for strength and durability.
Polystyrene impact-resistant wall moldingProduction is carried out in South Korea on modern high-precision equipment using advanced extrusion technologies. Multi-stage quality control includes checking geometric dimensions, strength tests, and surface inspection. The manufacturing accuracy ensures perfect element alignment during installation.
TR20 is manufactured from high-tech duro-polymer with unique operational characteristics.
Material Advantages
Impact-resistant polystyrene wall moldingHigh material density ensures exceptional mechanical strength and resistance to impact loads. The molding does not deform under its own weight even over large spans, maintaining perfectly flat geometry for decades. The square cross-section further increases the profile's rigidity, making it resistant to mechanical impacts.
Absolute moisture resistance with zero water absorption makes duro-polymer an ideal choice for rooms of any humidity level. The molding can be safely used in bathrooms, showers, saunas, pools, and kitchens. The material does not swell, deform, or lose strength when humidity fluctuates from zero to 100 percent.
TR20 operates over a wide temperature range from minus 50 to plus 80 degrees Celsius. The material does not become brittle at low temperatures and does not soften when heated, making it suitable for any climate conditions.
TR12 over a wide temperature range from -40 to +70 degrees Celsius. The material does not become brittle in cold and does not soften upon heating within normal room temperatures. This makes the molding suitable for use in unheated rooms, balconies, and loggias.polystyrene molding on the wallEcological safety is confirmed by international certificates. Duro-polymer contains no harmful substances and does not emit toxic vapors under any operating conditions.
Biological resistance provides complete protection against mold, fungi, bacteria, and insect pests. The material is not susceptible to rot and retains its properties even under conditions of increased humidity and heat.

TR20 and where to use it – the versatility of the square profile opens up wide possibilities.
Areas of application
how to cut polystyrene moldingCasing gaps between ceiling and wall – a classic application of TR20 molding. The square cross-section creates a clear, neat line that masks technological gaps and surface irregularities at junctions. The molding gives the interior a finished and neat appearance.
Creating wall frames and panels – a popular decorative application. With TR20, you can form rectangular or square compositions on walls. The 20x20 millimeter square cross-section creates a balanced frame suitable for medium-sized panels.
Casing mirrors and pictures – an elegant solution. The TR20 square profile creates a modern minimalist frame that highlights the content without distracting with excessive decoration.
Wall zoning – an effective design technique.

The clear line of the square profile creates a striking boundary.How to cut polystyrene moldingFurnishing decoration – a modern application of molding. TR20 is glued to furniture facades, creating geometric compositions in minimalist or modern styles.
Masking finish defects – a practical application. The molding covers unevenness, cracks, and joints between different materials, giving the surface a neat appearance.
Creating decorative lines – an architectural technique. Horizontal or vertical TR20 lines on walls create rhythm and structure in interiors.
TR20 can be installed independently, following professional technology.
Installation technology

Professional-grade miter saw is necessary for precise cutting of angles. The square cross-section requires special precision when cutting at 45 degrees.
Miter saw ensures maximum precision for the square profile, where any deviation will be noticeable.
Miter saw ensures maximum precision for the square profile, where any deviation will be noticeable.
Surface preparation includes cleaning, leveling, and mandatory priming for maximum adhesive bond strength.
Adhesive selection – the manufacturer recommends specialized Hi Wood adhesives (HD700, HD1000) or high-quality liquid nails for polystyrene.
Adhesive is applied in a continuous line or with frequent dots spaced 7-10 centimeters apart. After application, a pause of 2-3 minutes is required.
Attachment requires even pressing along the entire length with additional fixation using painter's tape until the adhesive dries.
Joining square-profile corners requires precise 45-degree cuts for tight edge alignment.
Final finishing includes sealing joints with acrylic sealant or HD500 adhesive putty.
TR20 finishing does not require prior priming. Apply 2-3 coats of paint with full drying time between layers.
Care and Maintenance
TR20 molding does not require complex maintenance due to duro-polymer properties. Regular dry cleaning with a soft cloth removes dust. Wet cleaning is permitted with non-abrasive cleaning agents. The material is resistant to mechanical impacts and retains its original appearance for decades.
