Here at Native Woodcraft, all of our panel products are made from CD grade plywood. This means it has a C grade face and a D grade low appearance “back” with permitted defects as per industry standards.
For further explanation about plywood grades, see below.
Plywood veneers for general purposes are graded from A grade being the top clear grade to D grade being the bottom or lowest. B grade is slightly lower than A. C grade has any knots, splits, etc filled and is then sanded. D grade can have open knots and splits and can be unsanded.
The face grade of plywood is always the first designated:
AA has two A grade faces.
AD has an A grade face and a D grade back.
S Selected grade, equals or betters B grade.
BB has two B grade faces.
CD has a C grade face and a D grade back.
DD has two D grade faces.
A High quality face, suitable for clear finishing.
B High quality surface suitable for painting.
S High quality surface suitable for painting.
C Non appearance grade with a solid face, not meant to look attractive.
D Low appearance grade with permitted defects.
PG Non-structural, for packing use, unsanded rough appearance.
