Premium Composite Decking Board Grey (3600x150x25MM) From £21.50/Board

Q: What size are the black composite decking boards?

Each board measures 3600 mm × 150 mm × 25 mm (3.6m length), covering 0.54 m² per plank. They are ideal for residential garden decks, elevated balconies, steps, and commercial venues.

Q: Are black composite boards slippery when wet or frosted?

No. Both faces carry an anti-slip high-traction textured coating, providing safe grip during rain, frost, and around wet areas like swimming pools or hot tubs.

Q: Will the black colour fade over time in sunlight?

No. The advanced UV-stabilised surface coating heavily resists solar fading, retaining its rich charcoal-black finish season after season without any oiling or staining.

Q: Do black composite boards require painting or oiling?

Never. Unlike timber, WPC composite boards require no staining, painting, oiling, or sanding. Simply clean with soapy water or a light pressure wash as needed.

Bring a sleek, ultra-modern edge to your outdoor living space with Black Composite Decking Boards (SKU: PS-DECKING-BLACK) from Paving and Slabs Ltd. Engineered from premium WPC (wood plastic composite), these anthracite and charcoal deck boards combine the organic character of timber with the high-impact durability of dense polymers—with zero ongoing maintenance required. Designed for homes and commercial venues across Great Britain—including London, Birmingham, Manchester, Glasgow, and Bristol—these planks are ideal for residential garden patios, elevated verandas, roof terraces, pub beer gardens, steps, and poolside decks.

Black Composite Decking Technical & Specification Summary

Product SKU: PS-DECKING-BLACK
Primary Materials: Recycled natural wood fibres & non-toxic dense polymers (WPC).
Layout Flexibility: Reversible dual-profile design (embossed woodgrain / linear grooved).
Safety Rating: High-grip anti-slip coating optimized for wet pool surrounds and steps.
Weather Resistance: Impervious to rain, frost, UV fading, rot, warping, and seasonal cracking.

Black WPC Decking Key Performance Benefits

Reversible Double-Sided Finish: Choose between rich embossed woodgrain or sleek linear grooved textures during installation.
Anti-Slip Traction Surface: High-friction safety profile engineered to prevent slipping in wet and frosty UK weather.
UV-Stabilised Shield: Capped polymer formula resists solar fading, maintaining deep charcoal tones in full sun.
Rot & Splinter-Free Construction: Non-porous core eliminates water absorption, fungal growth, and structural decay.
Low Maintenance Upkeep: No sanding, painting, oiling, or sealing needed—cleans easily with soapy water or light washing.

Reversible Double-Sided Architectural Styling

Customize your deck layout using our reversible board profile. Display the deep embossed woodgrain side upward to replicate traditional timber texture, or flip the board to show the clean linear grooved side for a contemporary industrial look. Manufactured from recycled timber fibres and dense polymers, this eco-friendly WPC structure remains rigid, scratch-resistant, and splinter-free under high foot traffic.

Weatherproof Capped WPC Material Built for the British Climate

Softwood timber decks degrade quickly in wet climates, requiring seasonal washing, oiling, and staining. Our black WPC composite decking planks eliminate these maintenance tasks completely. The moisture-resistant core blocks water penetration, preventing rot, mold, and seasonal warping. Comparing long-term decking investment against hardscaping?

Seamless Hidden Clip System & Subframe Assembly

Achieve a sleek, screw-free surface using hidden T-clip fasteners that slide directly into integrated side channels, creating correct 4mm expansion spacing while keeping fixings out of sight. These black composite boards can be mounted on timber joists, aluminium framing, or plastic subframes, and laid over concrete pads or existing paving using adjustable support pedestals. Complete your installation with matching corner trims, edge fascia boards, and outdoor living ranges:

Frequently Asked Questions

What size are the black composite decking boards?

Each board measures 3600 mm × 150 mm × 25 mm (3.6m length), covering 0.54 m² per plank. They are ideal for residential garden decks, elevated balconies, steps, and commercial venues.

Are black composite boards slippery when wet or frosted?

No. Both faces carry an anti-slip high-traction textured coating, providing safe grip during rain, frost, and around wet areas like swimming pools or hot tubs.

How do you stop rats and mice under composite decking?

To prevent rodents under decking, install fine galvanized pest mesh or wire netting across the subframe base before securing boards. Ensure perimeter composite edge trims or fascia boards leave no openings, and keep the sub-deck clearance clear of food waste.

Can you lay black composite decking on existing concrete or patio slabs?

Yes. Black composite decking can be installed directly over existing concrete bases or patio slabs by constructing a low-profile subframe using timber, aluminium, or plastic joists with support pedestals to allow water drainage and airflow.

Will the black colour fade over time in sunlight?

No. The advanced UV-stabilised surface coating heavily resists solar fading, retaining its rich charcoal-black finish season after season without any oiling or staining.

How many decking boards do I need per square metre?

Each 3.6m board covers 0.54 m² (approx. 1.85 boards per m² or 6.67 boards per linear metre of deck width). Add 5% for cut off-cuts. Use the coverage calculator above for an exact count based on your deck dimensions.

Do black composite boards require painting or oiling?

Never. Unlike timber, WPC composite boards require no staining, painting, oiling, or sanding. Simply clean with soapy water or a light pressure wash as needed.
