Beech plywood I
Features of wood: On surface of veneers can occur a slight variation of colour, sound and light knots, completely fused or partially fused small knots. A very small number of open cracks can occur if their filling is proper.
Production defects: Narrow cracks can occur, they are seasoned with putty and by wood inserts of similar colour, according to the PN-EN 635-2 norm.
Beech plywood II
Features of wood: There can occur needle knots in a limited number, sound knots, joined knots, spoiled knots and unfused knots. Closed cracks and sporadically open cracks can occur. Larval passages and bark beetle (Hylastes) can occur in small quantity.
Production defects: On a part of surface can occur sporadically open joints, glue breakthrough, roughness and unpolished places. One allows the limited amount of repair – patches, wedges, synthetic filling, if they are made tight. According to the PN-EN 635-2 norm.
Beech plywood III
Features of wood: On surface of veneers can occur in unlimited range such defects as: smudges and stains, blemishes, core spots, small and large sound knots, knot holes. On the other hand, range of defects occurrence is limited: rotten and unfused knots, open cracks.
Production defects: On surface of plywood can occur roughness and overgrinding. These are permissible: cracks and knot holes seasoned with putty or inserts, visible external and internal overlays. There can occur glue breakthrough and inclusions of foreign bodies with the exception of iron. Damage to the board edges of up to 5 mm
from its edge, while repairs can occur without restriction. Unlimited number of inserts.
Beech plywood is the board glued from uneven number of veneers, whose fibres in layers adjacent to each other run under a right angle. Upon the client’s request we can apply a different construction, e. g. all the layers running parallel to each other, owing to that we obtain greater bending strength.
We produce plywood in versions:
standard – combi plywood (beech veneers, internal layers – any type of wood) of
special design – of special design and quality of internal layers (e. g. beech plywood in full cross section, or full internal layers (for milling) etc.)
Upon a special order, we can process or refine the plywood. More information in the section: Machining.
Beech plywood is produced in accordance with the obligatory norms and has got the required certificates.
Due to its properties the pine plywood is applied in many branches.
Among others in the:
– upholstered furniture (elements of construction are invisible, half visible, visible)
– prefab/skeleton furniture, box-packed furniture (rear walls, side walls, front panels, shelves, drawers, school furniture – benches, chairs, stools, etc.)
-wood gallantry (flower shelves, shelves, racks, carpentry tables, workbenches, tables for sewing machines, drawing boards, feeders, cages, etc.)
– building woodwork (external and internal doors, shutters, doorframes, windowsills
– musical instruments
– stairs, stair risers
