Trex Coastal Bluff Composite Decking 12ft Riser

Trex Coastal Bluff Composite Decking 12ft Riser is designed to complete deck stair systems and vertical details with a clean, finished appearance. Used on stair faces and other vertical applications, this riser board helps conceal framing and creates a cohesive look that matches the rest of the deck surface.

Coastal Bluff features a soft, sun-washed taupe colour with subtle wood-grain detailing, inspired by weathered coastal hardwood. Its light, neutral tone brightens outdoor spaces and pairs effortlessly with black, white, bronze, or stainless-steel railings, as well as stone, brick, and modern exterior finishes.

Manufactured from a blend of recycled plastic film and reclaimed wood fibers, Trex Coastal Bluff Composite Decking 12ft Riser resists fading, staining, moisture absorption, warping, and splintering. Unlike traditional wood risers, it does not require sanding, staining, sealing, or painting, making it an ideal low-maintenance solution for high-visibility areas like stairs.

Built for year-round outdoor use, this riser performs reliably through sun exposure, rain, snow, and freeze–thaw cycles. It maintains its shape and appearance over time while remaining easy to clean and comfortable to the touch.

Backed by a 25-Year Limited Residential Fade & Stain Warranty, Trex Coastal Bluff Composite Decking 12ft Riser risers provide long-lasting durability and a polished finish for any deck project.
