Plywood

Plywood is an assembly of wood veneers (Thin layers of wood peeled from trunk logs) bonded together using resin (glue) to produce a flat sheet which is dimensionally and structurally stronger than solid wood. An extremely versatile product, plywood has its usage in a wide range of structural, interior and exterior applications – from form-work through to internal panelling. While plywood can be tailored/manufactured to suit an extensive range of applications, a normal ply panel consists of at least 3 plies and can extend up to 15 plies or more, with the wood grain in alternate plies running at right angles to each other.
Plywood can be sub-divided into four groups, depending upon specific applications
