Plywood Grade (1-2) – US Plywood Standard (APA PS1-95 Construction and Industrial Plywood)
According to US Plywood Standard (APA PS1-95 Construction and Industrial Plywood), plywood can be classified into several grades, such as A-A, A-B, A-C, B-B, B-C, C-C , C-D . The grade refers to the grade of surface covering. The first letter refers to the grade of face veneers and the second letter refers to the grade of back veneers . The better the grade, the nicer the surface.
The following is a guide to these plywood grades .
1. A-A grade: is high grade . The face/back of plywood are both A grade . This grade is very expensive and is used for nice furniture or decoration requiring both sides of plywood to be nice and visible .
2. A-B grade: is high grade , too . Because the face is A grade and back is B grade, so the plywood is suitable for applications where face should be nice but back is less important, such as furniture, cabinets ……
3. A-C grade: is “economical” high grade . This grade is suitable for applications where (like roof overhangs) face is important but back is not important . Using C grade back is a good method to reasonably save costs .
4. B-B grade: is common grade for general usages . This grade is suitable for applications where face/back is not very important but should still be good .
5. B-C grade: is economical, common and utility grade . Usually, as for general usages, B grade face is OK while the back is not important . Thus using C grade back can save costs .
6. C-C grade: is economical, common and utility grade . Used where face/back are not important but the panel should be strong enough.
7. C-D grade: is cheap and utility grade .
I’m in Atlanta, GA.
Where does it state that 23/32″ cdx plywood has 5 plys?
I am an architect. I need to specify fire rated plywood (MR) for a commercial building exterior with Florida product approval and installation details. If you can provide this I would appreciate it very much. Thank you. Phil Clark Philip J Clark Architect Pl
I will confirm with you about your required specification
I have not heard the 23/32″ cdx plywood should has 5 plys. 23/32″ cdx plywood can have 13plys, 11 plies, 9 plies or 5 plies.
Dear pan
How the price differs between the different grades ? For exemple between A-A grade and B-B grade ? I mean as a percentage
There is no a fixed percentage between The prices of different grades. The price difference between grades varies in Big Range in different Species of plywood.
