Since 1996 Trex has invented, defined and perfected the composite deck category, becoming the world's largest manufacturer of wood-alternative decking products. Never content to settle, we continue to make strides in outdoor engineering, melding innovation with environmental responsibility and beautiful form with powerful function.
Formed in 1996 through the buyout of a division of Mobil Corporation, our company went public in 1999. Today we offer the industry's widest array of high-performance composite products, which are available in more than 42 countries around the world. With the largest market share of composite decking in North America, a growing international footprint and more than $740,000,000 in annual sales, we lead the industry on a global scale.

          ** NOTE TO SPECIFIER ** In our survey of deck builders, we learned that 98% of 8-10 year-old decks have splitting, rotting and decay. For the $8,000 to $10,000 price of the average deck*, wouldn't it be wise to spend a few extra dollars to protect the life of your deck? Trex Protect acts as a moisture barrier between wood and galvanized metal, helping screws hold longer and stronger so you get the full life out of your deck. Delete if not required.
