Baltic (Russia ) Birch Plywood inspection
Baltic Birch (or Russian Birch) plywood is uniquely manufactured plywood consisting of multiple ply layers of Birch veneer per sheet. Each layer of birch veneer is peeled at 1.3mm or 1.5mm thickness giving the panel a multi-ply edge that is aesthetically attractive and offers unparalleled strength and stability. This plywood type offers a virtually void-free construction offering you great machinability and tremendous screw holding strength when compared to other ply substrates. Baltic Birch plywood from Russia was historically available only in 5ft x5ft panel formats .
Baltic Birch is available in a wide range of standard thicknesses: 3mm, 6mm, 9mm, 12mm, 15mm, 18mm, 25mm
Face grades of Baltic Birch plywood:
B/BB: Single piece face and back veneer. Face veneer is considered clear and free of defects with a light-uniform color. Back face allows color matched patches, which are oval or irregular in shape.
BB/BB: Single piece face and back. Both face and back veneers allow small color-matched patches on average and some light mineral streaks. Tight pin knots may be present.
BB/CP: Single piece face and back. The “CP” back veneers are downgraded from “BB” grade veneers, which allow for unlimited patches and sound knots, but does not allow for open defects.
CP/CP: Single piece face and back. Face and back grade veneers allow unlimited sound knots and repaired splits and unlimited patches. The panel is sound both sides and designed for laminating.
C/C: Patches, open knots, and small veneer splits allowed. Veneer lap and small core voids permitted. This panel is not sanded and would only be used for structural purposes.
