Build complex structures using the AliDeck Supa Joist
The AliDeck Supa Joist was designed to provide the versatility to act not only as a support beam but also as a post. This heavy-duty joist allows for structures of any size and shape to be constructed from scratch, to create raised deck areas, steps, walkways, and much more.
By coupling the Supa Joist with our Adjustable Feet, and our L and T brackets strong and stable build-up can be easily achieved. AliDeck Nosing Profile can be applied to the risers of constructed steps to provide a neat and aesthetic finish.
Once your raised platform structure is in place, it is then a simple task to install your AliDeck aluminium decking boards.
The Supa Joist is a large spanning, heavy duty aluminium support beam. Capable of spanning 3 metres, the Supa Joist has been cleverly designed to allow multiple joists to be connected together to achieve even greater strength for applications where larger spans are required.
The Supa Joist is compatible with the entire AliDeck range of boards, pedestals, and accessories.
Aluminium joists are far superior than timber or steel joists as they will not rot or rust; aluminium is naturally resistant to corrosion. Aluminium is also non-combustible, making it the only viable option when used in areas that require fire-resistant materials only.
