Ensuring that your project begins correctly is essential, and our structural composite joists can help you achieve that by providing a strong foundation for your deck boards or cladding to be placed correctly. Ideally placed onto a concrete base, these structural composite decking joists are made from recycled plastics and measure 4000mm x 100mm x 50mm.
The structural composite joists come in charcoal colour only. However, their colour does not need to match the rest of your installation as they will be installed within the foundations and can be hidden with Decking Boards and Fascia Boards.
Joist Specification
When building elevated decked areas, you need reliable support for your decking joists. Our structural composite joists are designed to provide just that, ensuring hard-wearing and long-lasting use for years to come.
If a solid concrete base isn’t an option, you can also place the structural composite joists directly onto the grass. To ensure maximum strength and reliability, we recommend purchasing one structural composite joist for every square meter of decking, with a maximum spacing of 400mm between each joist. For detailed installation instructions, please consult our installation guides.
Please note that Cladco Structural Joists require support every 1m for the structure of the joist itself. When installing composite decking onto structural joists, we advise 400mm centres. For PVC decking installations, we advise 300mm centres.
