Trex Beach Dune Composite Decking 16ft Grooved

Trex Beach Dune Composite Decking 16ft Grooved Board brings together the low-maintenance durability of composite decking and a warm, natural aesthetic ideal for residential decks. Its grooved edge is engineered for hidden-fastener installation, delivering a clean, screw-free deck surface that looks sleek and modern. At 16 ft length, this board offers a balance between manageable handling and long deck runs with fewer seams.

“Beach Dune” is characterized by a soft sandy-brown tone with a subtle wood-grain texture, evoking a relaxed, beach-inspired look that complements many architectural styles  from classic suburban homes to contemporary cottages.

Trex’s Enhance collection (which includes Beach Dune) is produced from a mix of recycled plastic film and reclaimed wood fibers making this decking board a durable, sustainable, low-maintenance alternative to traditional wood.
