Plywood

Our plywood is a wood based panel product consisting of an assembly of plies bonded together. The direction of the grain in adjacent plies is at right angles with the outer and inner plies placed symmetrically on each side of a central ply or core.

PLYWOOD
Our plywood is a wood based panel product consisting of an assembly of plies bonded together. The direction of the grain in adjacent plies is at right angles with the outer and inner plies placed symmetrically on each side of a central ply or core. We offer 3 product standards: JPIC standard, IHPA standard, and BS standards. These plywood standards can survive full exposure to weather for a few years. They withstand cold water for a long period of time and hot water for a limited time, but fail when exposed to boiling water. They are resistant to attack by micro organisms. Our British Standard plywood also offers additional properties which are highly resistant to weather, micro-organisms, cold, boiling water, wet and dry heat.
