Our aluminium decking joists (3.6m) are designed for superior strength and long-lasting performance, making them the ideal solution for your raised composite decking project. Made from high-quality T6 aluminium, these aluminium joists offer exceptional corrosion resistance while remaining lightweight for easy handling and installation. The black powder-coated finish provides extra protection and ensures a discreet appearance beneath your deck.

Before installation, ensure you lay a weed membrane over any soil, grass, or previous vegetation areas to prevent unwanted growth beneath your deck.

Measuring 75mm (H) x 40mm (W) x 3600mm (L), these aluminium joists require adjustable pedestal supports every 1.2 metres, reducing the number of supports needed, which saves both time and money. This efficient design makes our aluminium decking frame perfect for creating a stable and durable foundation for your decking boards, whether you’re a professional contractor or a DIY enthusiast.

Securing the aluminium joists into position is straightforward, especially when using our decking clips supplied with self-drilling screws, ensuring a secure and stable decking structure. Perfect for creating raised deck areas, our aluminium joists offer the strength and durability you need for a deck that’s built to last.

Aluminium Joist FAQs

Are aluminium decking joists easy to install?

Yes, aluminium joists are lightweight and easy to handle. They can be quickly secured into place using self-drilling screws, and the spacing of pedestal supports at 1.2m further simplifies the process.
Aluminium joists are more durable and weather-resistant than timber. They won’t warp, rot, or crack over time, making them a more reliable choice for decking substructures in outdoor environments. Alternatively for non raised decks, our composite joist may be a more affordable option.
Yes, aluminium decking joists are suitable for both residential and commercial projects. Their strength, corrosion resistance, and ease of installation make them a versatile option for any decking application.

    Had Dino decking boards with a wooden subframe but they started to rot so they had to go so ordered 5 aluminium joists to replace it, they all had to be shortened by 1 mtr they cut easily with a hacksaw and fitted where the wooden subframe was with the new screw pack which was larger than the old brackets it all went down very nicely looks very good and no worries about subframe rotting now very happy
