Trex Company is one of the nation's largest manufacturers of composite decking and railing, with more than 13 years of product experience. Products are marketed under the brand name Trex. Made from a unique formulation of reclaimed wood and plastic combined through a proprietary process, Trex s decking and railing products offer significant design flexibility with fewer ongoing maintenance requirements than wood. Trex Company turns millions of pounds of recycled and reclaimed plastic and waste wood each year into Trex decking. Most of these raw materials come from recycled plastic grocery bags, reclaimed pallet wrap and waste wood. The company purchases approximately 300 million pounds of used polyethylene and hardwood sawdust each year, materials that would normally end up in a landfill.
