Plywood is a panel product consisting of thin wood veneers (plies) glued together so that the grain direction of each layer of veneer is perpendicular to that of the adjacent layers.
This cross-lamination provides excellent two-way strength and stiffness properties, resistance to impact damage, and dimensional stability when wet.
