Cladco 4m Composite Joists


So, you’ve got your project planned using our range of Composite Decking options. Now you need Composite Decking Joists to help this vision come to life. As the first section to be considered before putting together your Decking or cladding support, composite joists are a vital component. Each of our composite joists come in one colour option of charcoal.

Each joist measures: 4000mm x 50mm x 30mm.

Each Joist weighs approximately 5.16kg.

Each Joist should be spaced no more than a maximum of 400mm apart for Decking.

Each Joist should be spaced no more than a maximum of 500mm apart for Cladding.

We recommend, as a rule of thumb, purchasing 1x Joist per square metre of Decking.

While Composite Joists are designed for Cladco Decking®, However, Joists can also be utilised for most domestic Decking and Wall Cladding projects. We highly recommend the Joist to be used in conjunction with a hard concrete base. This ensures the Joist support substructure is sturdy and reliable to use for the rest of your project. Purchasing 1x Joist per square metre of Decking and spacing them no more than 400mm apart is highly recommended.
