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.
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
Light and strong, easy to cut and drill. Perfect for decking support
These joists are excellent and very light weight
I would highly recommend
The aluminium joists and adjustable plastic pedestals were perfect for my decking project 👌
Ordered Aluminium joists -very good price, and quickly delivered.
They worked well for spanning an old pond with a mid way support, easy to fix to with the self drilling screws supplied.
