Bring a sleek, ultra-modern edge to your outdoor space with our Black Composite Decking Boards from Paving and Slabs Ltd. Engineered from premium WPC (wood plastic composite), these anthracite deck boards combine the natural warmth of timber with the heavy-duty longevity of advanced polymers — with no ongoing maintenance whatsoever. Ideal for residential patios, roof terraces, commercial beer gardens, and clean pool surroundings.

Reversible Double-Sided Design

Flip the board at installation to choose your finish. The deep embossed woodgrain side delivers classic timber warmth; the clean linear grooved side creates a contemporary industrial aesthetic. One board — two completely different looks.

Built for the British Climate

Traditional softwood decks rot, warp, and require annual sanding and staining. Our non-porous composite core blocks moisture absorption completely — no rot, no algae, no seasonal twisting. The advanced UV-stabilised surface resists solar fading, retaining that rich charcoal-black finish year after year, entirely maintenance-free. Compare the long-term costs in our composite decking vs patio slabs cost guide.

Clean, Hidden Installation

Hidden clip fasteners slide into the integrated side channels for a completely screw-free, splinter-free surface. Safe for bare feet, children, and pets. For design calculation tips, see our guide on how to calculate how much composite decking you need.
