High-Density Polyethylene

An outstanding wood replacement, High-Density Polyethylene (HDPE) is a strong, durable, and long-lasting building material that can be customized for a wide range of commercial and residential uses. HDPE poly lumber can replace traditional wood in a variety of applications including agricultural, industrial, freight and transit, outdoor furnishings and more.

Just Like Wood, but Better

It’s not real wood, but it offers many of the advantages of traditional lumber. Like regular lumber, our material can be shaped with everything from standard tools to CNC machines. However, our material lasts longer and is easier to maintain. Where natural wood faces degradation from the elements, our poly lumber is weatherproof and extremely durable.

Engineered to Last

The best way to do maintenance is not at all. Our material won’t splinter, warp or fade and never needs paint or stain. Our colors stay true and the product dimensions are forever stable. When you use our materials rest assured that they will stand the test of time and the punishment of harsh environments.
