Peeled veneer - veneer, produced from wood of birch, beech, oak, fur-trees, alder, aspen, pine as well as from other types of wood.

Peeled veneer it is used:
  • For manufacture of plywood, plywood panels, laminated-wood plastics and other kinds laminated glued wood;
  • For veneering of parts and units in woodwork products;
  • In manufacture of matches.

  • Composite plywood - plywood (plywood panel) with layers of veneer, made of various types of wood, which are located symmetrically in respect of the central layer.
    Veneer used for production of composite plywood is 1.5 mm thick. External veneer is fabricated from birch, the internal one represents alternation of birch veneer and veneer from wood of coniferous types. The combined plywood is versatile and possesses sufficient durability.
