Trex Company
At Trex, we don't just make composite decking -- we invented it. From there, we continue to innovate, engineering what's next in outdoor living to perfect and define the composite deck category. It's what's made us the world's largest manufacturer of wood-alternative decking products. And it's a product both our customers and our team members can be proud of: every board we make is more than 95% recycled materials, including reclaimed wood and recycled plastic film. Build a career you can be proud of. The work you put in, the ideas you bring, the rewards you earn—when you’ve got pride in what you create, it’s all worth the effort. As the industry leader, we feel it. And you will, too.
