Aluminium Deck Joists

The perfect solution for your decking


Aluminium deck joists are the perfect solution for your decking: no rot, no maintenance, never ending. It means very cheap in the long term. Deck support joists are an essential component for your decking project.

Usually, when thinking about buying decking, we only consider the boards and the fixings.  Using aluminium provides a warp free solution for fitting composite decking. Extreme weather will not distort the aluminium joists nor will it rot unlike timber joists. Aluminium can be fixed to the composite decking boards via hidden clips. If you are considering composite decking we recommend investing in aluminium joists making your beautiful decking last for years to come due to its sturdy aluminium foundations.

At BuildDeck, we want you to get the best on every project! A universal joisting system designed specifically to suit our boards and fixings.
