Structural plywood is load-bearing plywood with a low requirement for appearances.
The structural plywood is manufactured with WBP Phenolic glue. This type of panel will not weaken if exposed to wet conditions as well as temperature changes.
The most structural plywood are made with conifer softwood veneers like radiata pine or larch. Knots are allowed on both surfaces of the plywood.
Structural plywood with conifer wood faces is often excluded from the anti-dumping on Chinese plywood.
