BIRCH - RUSSIAN/BALTIC 12mm (1/2") 2,440mm x 1,220mm (96" x 48")           BB/CP - 9 PLY VENEER CORE Russian Birch plywood is desired for its multiple plies of birch veneer that provide superior stability and strength. Russian Birch plywood is typically produced with all birch veneers. Russian Birch is a white wood, with a more open grain than domestic Birch, and slightly less dense than domestic Birch. Russian Birch is commonly used in the construction of drawer boxes. This multi layer core produces an attractive top edge without having to edgeband the top edge of the drawer box. Please note that Russian manufacturers and distributors handle markings as Length x Width (Length is along the long grain side of the panel). Due to the nature of plywood manufacturing, mills allow for a certain percentage of "falling sizes," which is a byproduct of a full format panel such as 1,525mm x 1,525mm. A falling size panel can have one or more sides shorter than a full-length or a full-width panel. 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. 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. Product Downloads: Material Safety Data Sheet
