Structural Composite Lumber (SCL) is a family of engineered wood products that combine wood fiber with exterior-type adhesives to form lumber products of virtually any cross-sectional size. The wood fiber may be in the form of veneers, strands, or a combination thereof, bonded together with wet-use structural adhesives. Materials which do not conform to the definitions below are beyond the scope of this standard. See more
