Birch throughout Plywood ideal for machining, routing and cutting for internal applications. Laser grade plywood has an interior glue line that minimises burning and scorching when cut or engraved with a laser.

BB grade plywood is mainly solid veneers with only small repaired veneer splits and pin knots allowed. Larger open knots are repaired with wooden plugs/patches. Generally considered as ‘paint grade’ and used where a solid surface is needed but the visual aspects are not so critical.
