General purpose plywood

Plywood is a light material, uniform, durable, resistant to crushing, bending, stretching, tearing, and at the same time very flexible and easy to precision machining. Can be bent, allows for precise cutting out shapes and holes, both using hand tools and CNC machine type.

WYMIAR

2 130 x 1 250 mm

THICKNESS

4-50 mm

VENEER THICKNESS

1,4 - 1,7 mm

WOOD SPECIES

birch, alder, beech, pine (mixed))

GLUE TYPE

phenol-formaldehyde (exterior plywood for general purposes), urea-formaldehyde (interior plywood for general purposes)

HYGIENIC CLASS

E1

Depending on requirements and further use of plywood, select a quality of outer layer. We distinguish three classes of quality (I, II and III), where class I has minimum acceptable defects. Right can thus be finished in quality class of I to III, while the Left always corresponds to quality class of III.
