Structural Plywood

Loading bearing plywood made with WBP glue and pine veneers.

Structural Plywood

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.

Features

High Strength

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.

Water Proof

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.

Less Attractive

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.

Uses

FAQ

What is structural plywood designed for?

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.

What is the difference between structural plywood and non-structural plywood?

Structual plywood is very dense. It is compressed harder than the non-structural plywood with much better glue.

Is structural plywood a marine grade plywood?

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.

What is structural plywood made of?

Structural plywood are often made with WBP glue and conifer veneers like radiata pine, larch, etc.
