Plastic Lumber Construction
How ACT Timbers are Constructed
Not all plastics are considered composites. When additional strength is required, many types of polymers (plastics) can be reinforced with structural materials to meet the higher performance demands. Only when a polymer is reinforced is it considered a fiber-reinforced polymer (FRP) composite.
Composition by Weight
Maximum, RECYCLED POLYETHYLENE: HDPE = 80% Maximum, FIBERGLASS REINFORCING AGENT CONTENT = 20% Additives to ensure UV stabilization and flame retardancy may total no more than 2%
ACT Timbers are manufactured using a process known as extrusion. The finished product is a continuous, homogenous section that has fiberglass throughout to enhance the strength and stiffness of the timber. ACT is manufactured in a range of industry standard dimensions and lengths and can be manufactured in tongue & groove and ship-lap profiles.
