Trex Clam Shell Composite Decking 20ft Solid

Trex Clam Shell Composite Decking 20ft Solid Board is designed for deck areas where visible edges, borders, and detailed finishing are required. Its solid (square-edge) profile makes it ideal for picture-frame layouts, stair treads, perimeter boards, and any application where a clean, finished edge is essential.

Part of the Trex Enhance Basics collection, this board offers dependable composite performance with minimal upkeep. It is engineered to resist moisture, surface wear, and colour fading while maintaining a uniform appearance over time. The result is a durable, low-maintenance decking solution suited for both modern and traditional residential designs.

Color & Appearance

Clam Shell features a medium-grey tone with a subtle, wood-like grain pattern — a contemporary, easy-to-match shade that works well with a variety of exterior materials (stone, siding, railings, furniture). This neutral grey makes it suitable for modern, rustic, coastal, or transitional-style homes.
