HDF (hardboard)

Hardboards are manufactured from softwood and hardwood fibres. It is a high quality product resistant to physical impact, designed for indoor applications.
Hardboards are widely used in production of internal planes of furniture, decoration of residential and public premises as well as a whole range of consumer goods and other products used in low-humidity conditions.
These boards are perfectly suited for :
Furniture production (cabinet internal walls, drawer bottoms, upholstery furniture components, bed/couch bottoms);
Interior and exhibition stands (walls, exhibition components, decorations, base for paintings);
Production of rigid packaging.

Oriented strand board (OSB)

OSB - oriented strand board. These are made from several layers of wood strands covered with advanced technology resins and compressed in a hot press. These boards are used in the construction of frame houses, roofing (under bituminous tiles), laying a floor (under parquet, carpeting and PVC coatings), installing temporary premises, in the manufacture of furniture, interior decoration.
Physical - mechanical properties
Thickness tolerances ±0.8 mm
Width and length tolerances ±3 mm
Angle tolerance ±1.5 mm/1m
Edge straightness ±2 mm/1m

PLYWOOD

Birch plywood have warmth and a nice wood texture. Birch plywood is used in the production of furniture and packing, interior decoration and construction. Plywood is made by bonding together three or more 1.4 mm thick birch veneers. Plywood is classified into grades depending on veneers face and their processing quality. The grades of plywood determine their quality and the field of application.
Technical data:
Sizes (mm) : 1525x1525, 1525x1475, 1475x1475
Thickness (mm) : 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 21, 24
Emission class : E1
Density : 640-700 kg/m3
Moisture : 8-10%
The surface of plywood of all grades, except IV, can be sanded or unsanded.
Wood type : birch, alder
Country of origin : Russia, Belarus, Latvia

Grade

Description

B(I)

Surface smooth, free of knots and patches.

BB(II)

Surface free of knots; knots are cut out and filled with patches.

C(IV)
