Begin Your Aluminium Decking Project With Our Aluminium Joists

Creating the supportive foundation for your aluminium decking boards is vital to ensure a high-quality finished product. Cladco aluminium joists will enable you to correctly install your decking boards upon a secure and supportive substructure.

These Joists can also be installed as a supportive substructure for timber and composite decking installations as well as aluminium boards.

Joists specifications

Length: 4m
Width: 50mm
Thickness: 50mm
Weight: 4.04kg approx.
Colour: Black
Material: Non-corrosive powder-coated aluminium

Manufactured from high-quality powder-coated aluminium, these joists are 4m in length and are available in black only. Due to the joists being concealed beneath the decking boards, they have no need to be colour-matched to the boards themselves.

These joists have an A2 fire rating alongside an S1 non-combustible rating and so can be installed in living spaces that are more than 18m high. Before carrying out any installation, ensure you have checked all information with your building regulator and contractor prior to purchase.

I replaced a small grass area as I wanted something that didn’t need any maintenance. These joists were easy to work with and install once the concrete was down. Definitely recommend.

I was surprised how light these joists are compared to the composite ones. My decking feels really stable and I am so pleased with how it looks. Cladco made everything very effortless, from ordering to delivery.
