Molded Grade Plastic Lumber Info

Molded Grade plastic lumber boards are a high-density polyethylene lumber that uses a different extrusion method, the result being a recycled plastic wood with a slightly rougher skin grain. This method also limits maximum length availability, and you are more likely to find internal “voids”, though usually small. Click Color Scans for larger view.

A small order fee adds an additional $35.00 to orders under $400.00 (before shipping)

Chemical Resistance

Since high density polyethylene has a high resistance to most acids and chemicals, Plastic Lumber is not affected by exposure to most substances.

Ultraviolet Weathering

An ultraviolet stabilizer is incorporated at the time of manufacture. It protects the plastic from ultraviolet light degradation and ensures that the outside of the product will not degrade in exterior applications.
