Trex Whidbey Composite Decking 12ft Grooved

The Trex Whidbey Composite Decking 12ft Grooved Board delivers refined coastal character paired with the highest level of durability in the Trex lineup. Designed with a grooved-edge profile, this board installs using hidden fasteners, creating a smooth, screw-free deck surface with a clean, architectural finish.

As part of the Trex Signature collection, Whidbey is engineered for superior performance and long-term beauty. Its advanced composite construction provides excellent resistance to moisture, fading, staining, and surface wear—making it a strong choice for Canadian climates exposed to sun, rain, snow, and freeze–thaw cycles.

Color & Appearance

Whidbey is a retreat to an island of misty cliffs, where salt-washed fog rolls in like a grey morning blanket. This soft, atmospheric grey tone delivers a calm, understated elegance that feels both modern and timeless. The subtle wood-grain texture adds depth without overpowering the colour, making Whidbey ideal for coastal, contemporary, and minimalist outdoor designs. It pairs effortlessly with black, white, bronze, or stainless-steel railings, as well as stone, concrete, and neutral exterior finishes.
