2.0 Plastic Lumber Specifications

2.1 Description

2.1.1 Structural plastic lumber shall be manufactured with HDPE and fiberglass elements to act as reinforcement with HDPE. Lumber shall be molded in one piece per specified size. All materials will have UV additives to prevent deterioration of the plastic lumber from exposure to UV light. HDPE will be made up of recycled material; both post-industrial & post-consumer, excluding additives and colorants. Finished plastic lumber will not rot, split, crack or splinter for a minimum of 50 years. It shall be resistant to termites, marine borers, salt spray, oil and fungus.

2.2 Terminology

2.2.1 Recycled Plastic Lumber (RPL) – Recycled plastic lumber is defined as molded plastic supplied in traditional dimensional lumber sizes and manufactured using at least 50% recycled materials.

2.2.2 High Density Polyethylene – (HDPE) – Defined as a stiff plastic resin used extensively by the food industry to mold bottles and trays. This resin is resistant to most chemicals and absorbs almost no moisture making it an excellent building material.

2.2.3 Structural Grade Plastic Lumber (SGPL) – Structural Grade Plastic Lumber is primarily standard recycled plastic lumber, with fiberglass strands and rebar rods added to increase structural strength. It should be noted along with increased strength, added benefits of (SGPL) are reduced creep deformation and reduced expansion and contraction due to temperatures changes.
