What Is Structural Plywood?
Structural plywood is manufactured from cross-laminated veneer layers bonded using a Type A phenol formaldehyde resin adhesive. The cross-grain construction increases load-bearing capacity, dimensional stability, resistance to moisture movement, and shear strength.
Unlike non-structural plywood, structural plywood is specifically engineered and graded for strength performance. The orientation of veneers alternates at 90 degrees between layers. This cross-lamination distributes loads evenly, reduces splitting, improves stiffness-to-weight ratio, enhancing durability under stress.
Structural plywood is commonly used where the panel forms part of the structural system of a building, not just decorative or lining applications.
