Trex decking is a composite decking material used as an alternative to wood decking. The decking looks similar to wood boards, but Trex uses 95 percent recycled materials to create the decking.
The recycled materials used in the Trex decking system are primarily plastics and wood byproducts such as sawdust, wood chips and wood fiber. The manufacturing processes involves mixing, heating and tinting the material. The manufacturer shapes the materials into boards. Trex offers three different lines of decking as of 2015. Other produces include deck railings, deck framing and fascia.
Trex decking costs more initially than a wood deck. The savings comes over time. A deck made with Trex material does not need sanding or staining like wood decks. Maintenance for the composite decking is an occasional scrub or power wash.
Composite decking features an outer layer or shell to protect the composite board. The outer layer protects the decking from weather elements. It also prevents scratches, fading, mold growth and stains. Trex decking boards won't rot or warp like wood deck boards.
Trex decking boards look similar to wood. They come in a variety of colors and grain patterns to create a natural look. The system allows for custom designs include curves in the boards.
