Structural Plastic Lumber | Fiberglass Reinforced Plywood

Structural Grade

    • Structural Grade

      The Structural Plastic Lumber has the same attributes as described for the molded grades with one major difference. The fiberglass reinforced plywood makes the lumber approximately 3 times stiffer than the molded or premium grades. These boards are the choice when free spans beyond the capability of the other grades are required. Common uses are for under-structure in deck dock and boardwalk construction, sign and fence posts though there are many other potential applications such as pergolas and arbors. This grade, because of the dense fiberglass additive is also the heaviest board on a size by size comparison with the other grades.
