Why Choose 4m Composite Decking Boards?

✔ Extra-Length for a Seamless Finish

Using 4m decking boards means fewer joins, a cleaner look, and faster installation. Longer boards help to reduce the number of connection points, creating a sleek, uninterrupted deck surface with greater structural integrity.

✔ Unrivalled Durability – Built to Last

Unlike traditional timber, these composite decking boards are engineered to resist:

✅ Warping, Splitting & Cracking – No risk of structural failure.
✅ Water Damage & Rot – Fully capped to prevent moisture ingress.
✅ UV & Fade Resistance – Maintains its colour even under intense sunlight.
✅ Mould, Algae & Stains – Designed for year-round outdoor use.

Each board is backed by a 10+ year warranty, ensuring long-term performance in the UK’s unpredictable climate.

✔ Timber-Look Decking...Without the Maintenance

Enjoy the beauty of wood without the time-consuming upkeep. Unlike timber decking, composite boards require:

❌ No sanding, sealing, or staining
❌ No risk of woodworm or insect damage
❌ No splinters – Safe for barefoot walking

Just an occasional wash with soapy water is enough to keep your decking looking brand new.

✔ Quick & Easy Installation

These lightweight yet strong 4m decking boards can be installed in just a few hours using a hidden clip system for a seamless, screw-free finish.

Step 3: Lay the Decking Boards

• Place each board, securing with hidden fastener clips for a sleek, screw-free surface.
