Composite decking—like Trex—is a blend of plastic film and wood fibers. The plastic film that goes into composite decking can include polypropylene or polyethylene. These plastics work well with wood fibers to create a strong, resilient material that is more stable than 100% plastic decking.

Is Trex better than wood?
