Grade E
Premium grade with a flawless appearance
Grade E plywood is the highest-quality class, produced from carefully selected birch veneer. Sheet surfaces are virtually flawless, with no visible defects or manufacturing imperfections.
Strict grading criteria:
Permitted: Only barely perceptible natural variations in the wood grain; dark pin knots are excluded.
Not permitted: Knots of any kind, including knot holes, wormholes, splits and brown streaks.
Technical parameters and tolerances:
Surface roughness (GOST 7016): Maximum 100 μm for sanded sheets and 200 μm for unsanded sheets.
Flatness (warping): Not specified for sheets thinner than 6.5 mm. For thicknesses of 6.5 mm and above, maximum diagonal deflection is 15 mm per metre of length.
Applications:
The refined surface grain is ideal for clear lacquer finishes. This grade is used in aircraft and mechanical engineering, precision construction and as a substrate for film facing. In furniture production, it is intended for premium doors, tables, chairs and cabinets.
