Aluminium Joist 3.6m

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 with our aluminium joist hangers and flat joining plates, 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.
