Russian Birch (Baltic Birch)

Russian Birch plywood is desired for its multiple plies of birch veneer that provide superior stability and strength. This panel is an exceptional performer when strength is desired, when either the face veneer or panel edges are exposed, or when a pleasing edge appearance is needed. Russian Birch plywood is typically produced with all birch veneers.

Grading Standards

Plywood panels can have faces and backs of different grades. In other words, the grade of panel with a BB face and a CP back would be BB/CP. Below is a generally description of the Russian Birch 10.55-71 grade specifications.

B – Select one-piece face has a uniform appearance and is free from defect. This face grade is uniformly sanded.

BB – One-piece face generally light and uniform in color. Pin knots and small sound tight knots are allowed. Occasional “football” patches are color matched to the veneer. Sanding is smooth.

CP – One-piece face similar to grade BB in quality. Sound knots and patches may be more common than BB grade. Small open splits, knot holes and double patches are allowed. May have some streaks and discoloration. Sanding is smooth.

C – Open defects, all sound defects, streaks and discoloration allowed. Does not have to be sanded.
