Cladco Aluminium Decking Joist

Cladco Aluminium Decking Joist
High‑Strength, Long‑Life Sub‑Frame Support

Cladco Aluminium Decking Joists provide a premium, long‑lasting and dimensionally stable sub‑frame solution for aluminium and composite decking installations. Manufactured from high‑grade, corrosion‑resistant aluminium, these joists offer exceptional structural strength and durability, making them ideal for outdoor environments where traditional timber joists may warp, rot or deteriorate over time.

Engineered for maximum stability, Cladco Aluminium Joists maintain their shape and performance in all weather conditions, resisting moisture, UV exposure and temperature‑related movement. Their lightweight yet robust construction makes them easy to handle and install, while providing a reliable, rigid base that enhances the lifespan and overall quality of your decking system.

Suitable for both residential and commercial projects, these joists deliver a professional, long‑term solution that supports heavy foot traffic, raised platforms and high‑exposure installations. When paired with Cladco Aluminium Decking and hidden‑fixing systems, they help create a strong, modern and low‑maintenance outdoor structure.
