Trex Pebble Grey Composite Decking 12ft Grooved

Trex Pebble Grey Composite Decking 12ft Grooved Board delivers a clean, contemporary look combined with the long-term durability and low-maintenance performance Trex is known for. Designed with a grooved-edge profile, this board is compatible with hidden fasteners, allowing for a smooth, screw-free deck surface that enhances both aesthetics and comfort.

Part of the Trex Select collection, Pebble Grey offers a practical balance of style and value. It resists fading, staining, moisture, warping, and splintering—making it an excellent choice for Canadian climates where decks are exposed to sun, rain, snow, and seasonal temperature changes.

Color & Appearance

Pebble Grey features a soft, neutral grey tone with subtle wood-grain texture, inspired by natural stone and weathered wood. This versatile colour provides a modern yet timeless appearance and pairs easily with black, white, charcoal, or stainless-steel railings, as well as stone, brick, and contemporary exterior finishes.
