Plywood is an assemblage of wood veneers bonded together to produce a flat sheet. While it can be tailored to suit an extensive range of applications, the normal product consists of at least 3 plies, with the grain in the alternate plies running at right angles. There are four groupings of plywood products, with each group designed for specific applications: Structural�  Exterior Interior Marine. Plywood offers the following benefits: Increased stability Plywood offers all the inherent advantages of the parent wood plus enhanced properties in its laminated structure. High impact resistance Being a wood based material, plywood has the ability to accommodate the occasional short-term overload; up to twice the design load. This is useful where seismic activity or cyclonic winds can occur. This property is also effective when used as construction flooring or as concrete formwork. Plywood's laminated structure distributes loads from impact over a larger area on the opposite face, which effectively reduces the tensile stress.
