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. Leveraging our success with decking led to the inclusion of other compatible products. Primary among them was composite fencing, a unique and innovative application of material that had already proven its value.
There's a reason we're the world's #1 composite fencing brand: we offer the most innovative, technologically advanced outdoor living products available today. As the first company to combine the durability of recycled plastic with the natural beauty of reclaimed wood in high-performance products, we lead the way in applying this proprietary technology to a wide variety of outdoor applications for low-maintenance, luxurious outdoor living.
Since its introduction in 2005, Trex Seclusions fencing has lead the way in establishing composite materials as high end alternatives to wood and vinyl. As the third generation in fencing, Trex composite combines a natural look with low maintenance. From the immediate exterior of your home to the perimeter of your property, Trex products truly define outdoor living.
