Plywood grades

We use four grades of birch veneer to produce UPG plywood: B, S (I), BB (II), CP (III), C (IV).

The plywood grades are formed from the veneer grades used in the outer layers - in the front and back side. For example, plywood with grade B veneer on the front and grade BB veneer on the back side are designated B/BB - the highest grade is specified first.

We offer a range of 8 products of four plywood grades.
