Structural plywood is load-bearing plywood with a low requirement for appearances. It is widely used in the construction where a strong board is needed.
The structural plywood is manufactured with WBP melamine glue or WBP phenolic glue. It is less attractive WBP plywood which will not weaken if exposed to wet conditions as well as temperature changes.
A typical structural plywood sheet is manufactured with conifer softwood veneers such as radiata pine or larch. Knots are allowed on both surfaces of the plywood. It is usually a pine throughout plywood. Structural plywood with conifer wood faces is often excluded from the anti-dumping on Chinese plywood.

Structural plywood are required to be very strong because of its load-bearing working conditions. Its compression ratio is higher than those of the decorative hardwood faced plywood.
Structural plywood need to be waterproof and humid resistant because it is often used in exposed conditions. WBP melamine or phenolic glue are used in the production.
Because they are covered, cheap price C or D grade veneers are chosen as the face veneer for structural board. That’s why some structural plywood are called CDX plywood.
Structural plywood is designed for building and construction purposes like beams and hoardings. But they can also be used in crates, internal structures, bins, boxes, and outdoor furniture. Some structural plywoods are also used for wall and roof bracing.
Structual plywood is very dense. It is compressed harder than the non-structural plywood with much better glue.
Yes because WBP glue are used in the production of structural plywood. Its only disadvantage to marine plywood is that its apprearance is not as good as theirs.
Structural plywood are often made with WBP glue and conifer veneers like radiata pine, larch, etc.
