PLYWOOD STRUCTURAL CD TREATED to H3, 2400 x 1200

Plywood H3 Treated

H3 Treated Structural Plywood is strong and stable, with a pre-sanded C-grade face panel available in a range of thicknesses.

The strongest, lightest, most versatile utility and decorative product made from a renewable resource, plywood is kilo for kilo stronger than steel.

Plywood was the first type of engineered wood to be invented. It is made from thin sheets of wood veneer, called plies or veneers. These are stacked together with the direction of each ply’s grain differing from its neighbours’ by 90° (cross banding). The plies are bonded under heat and pressure with strong adhesives, usually phenol formaldehyde resin, making plywood a type of composite material. Laminating an odd number of plies (3, 5, 7…) reduces warping while increasing the number of plies increases the resistance to shearing forces.

A common reason for using plywood instead of plain wood is its resistance to cracking, shrinkage, twisting/warping, and its general high degree of strength.

What Is C Grade Plywood?

When the veneer quality is C grade, it’s best used for non-decorative surfaces. C grade plywood generally contains knots, defects and filler and splits and although these have been filled, the appearance is still affected. Plywood with a C grade veneer face is used when a solid surface is needed on non-visual elements.

What Is D Grade Plywood?

D grade veneer face is a non-appearance grade plywood which can include open knots and defects that have not been filled. Because the finish can vary significantly, it’s best to limit its use to structural applications where aesthetics are not a concern.

What about the back?

The back veneer is graded using the same criteria as the face, and the grades can be different from front to back. For example, an AB graded sheet would have an A grade face and a B grade back, a CD refers to plywood with a C grade front and D grade back, and so on.

BENEFITS OF PLYWOOD

Renewable Resource – A natural product from a renewable resource.
Beautiful – Preferred because of its warmth and natural markings.
Strength – Unique cross-layered structure makes it kilo for kilo, stronger than steel.
Efficiency – Uses more of the log than timber.
Versatility – Can be bent and formed to meet various sizes and shapes.
Durability – Long-lasting and good resistance to damage.
