ALUMINIUM DOUBLE JOIST
COMPOSITE DECKING

Although these can’t be seen when your deck is complete, they are perhaps more important than your deck boards. Deck joists give you the framework to attach your decking boards to and play a very important part in ascertaining the strength and durability of your decking. If this part of the decking is skipped, you stand to compromise the service life, regardless of the quality of the deck boards. It is very important to check the installation guidelines for the deck boards before designing your substructure layout, its very important to check the joist spacing. Consideration should also be given to drainage and having a fall on the deck boards.

Our Aluminium joist support system is the ultimate design for decking support. The beams are manufactured from a lightweight structural aluminium with an anodized finish to preserve it life. It is designed to support any conventional decking systems, it is the perfect option for all decking applications. Our pedestal system will compliment any decking laid on our aluminium joists.
