Plywood is a multi-layered wood-based material produced by bonding cross-oriented veneer layers under pressure and heat. This composite structure provides high strength, dimensional stability, and reliable performance under moisture conditions.
Primarily from poplar veneer (main focus of our production) due to its excellent weight-to-strength ratio, stability, and ease of processing. Other wood types (e.g., birch) are used for specialized applications. Individual veneer layers are typically up to ~7 mm thick, with the total number of layers adjusted to achieve the desired panel thickness.
We use E1/A1 adhesives in compliance with European standards. After forming the “sandwich,” pressing (pressure + heat) is applied to polymerize the adhesive and permanently bond the layers, followed by cooling/conditioning to prevent deformation.
Panels are flattened (sanded) for a smooth surface and precise dimensions, then cut to size. If necessary, face/back defects are repaired and a quality grade assigned.
In addition to standard plywood, we offer LVL panels (all veneers aligned parallel) for applications where high load-bearing capacity in one direction is critical.

Poplar grows rapidly and enables renewable plantations, contributing to the protection of natural resources and reduction of CO2 emissions. Our plywood carries the FSC certificate, ensuring it comes from responsibly managed forests.

Ideal when priorities are: light weight, cost-effectiveness, ease of processing, good moisture resistance, and a locally sourced, sustainable material. For heavy structural elements or specialized decorative purposes, other wood types may be selected as needed.
Plywood production is a multi-stage, precisely controlled process — from selecting logs and veneer peeling to pressing, sanding, and certified delivery.
High-quality poplar logs are sourced from renewable plantations. Water transport is eco-friendly — reducing emissions and road traffic impact.
Logs are processed and peeled on rotary lathes, producing thin veneer sheets. Poplar is ideal due to its uniform structure, light weight, and ease of machining.
In continuous and batch dryers, the veneer is dried to 6–12% moisture — ensuring stability, preventing warping, and enabling optimal gluing.
Veneers are alternately stacked with and without adhesive (E1/A1), cross-oriented, forming a composite “sandwich.”
The veneer “sandwich” is pressed under pressure and temperature (typically 100–115 °C) — enabling adhesive polymerization and permanent bonding of layers.
Boards are gradually cooled and conditioned; temperature and moisture are equalized to prevent internal stresses and warping.
Surfaces are sanded for flatness; then cut to size and edges finished for a clean, precise final product.
Visual and mechanical inspections, grading, and labeling. Production complies with FSC and E1/A1 standards.
Finished boards are carefully packed and stored under controlled conditions, ready for fast and safe delivery.
Plywood is classified by the number of layers, wood species, adhesive type (interior/exterior), and surface finish. Discover the main types, LVL specials, standard dimensions, and key industrial applications.
Odd, symmetrical number of veneers (3, 5, 7…) for optimal stability. Board thickness depends on total layers (veneer ~7 mm each).
Poplar — standard: light weight, excellent machinability, stable. On request, birch for special requirements.
Adhesive type determines resistance: E1/A1 (European standard). Interior/exterior use according to waterproof class.
Sanded and dimensioned surface. Face/back repairs and grading according to quality are possible.
LVL (Laminated Veneer Lumber): all layers aligned in the same grain direction — maximum load-bearing capacity and stiffness along the length.
Applications: Structural beams, lintels, formwork, and all elements where linear load transfer is critical.
