Description
Our WPC composite joists can be used in conjunction with a hard concrete base to build a supporting substructure suitable for most domestic decks.
Each joist measures 4000mm x??50mm x 30mm and is only available in a single charcoal colour.
Each joist should be spaced no more than a maximum of 400m apart. As a rule of thumb we recommend purchasing 1 joist??per square metre of decking.
