Structural Ply

Structural plywood is a series of timber veneers glued and pressed at right angles to each other to form a rigid board. The veneers are coated with glue then hot pressed under extreme pressure to set the glue and Structural plywood is the result of this process.

Structural plywood is normally pressed in uneven layers of veneers. Different thickness veneers are utilised to achieve varying plywood thicknesses. Structural plywood is regularly tested to a minimum of F8 to ensure it’s structural integrity.

Thicknesses in our structural range vary from 7mm to 32mm. 4mm is also made to a structural standard, but is not thick enough to qualify for a structural rating.


CCA H3.2 (Copper Chrome Arsenic) – Structural plywood is generally impregnated to H3.2 hazard class with CCA treatment to AS/NZS1604.3:2002. H3.2 hazard class is described as: “outside, above ground, subject to periodic, moderate wetting and leaching”. Green in appearance. (C and D Grades). CCA waterborne preservative is used for structural plywood. It has a green colour, and is dried following treatment so that the sheets may return to the correct dimensions and are at a moisture content suited to use in building.
