Our composite decking joists are made from 100% recycled plastic and once installed, it will compliment your decking for years to come. Once installed the plastic joist requires no aftercare and the product will never rot.
Just like our composite decking boards, composite joists will not split, rot or stains thanks to the robust construction and hard-wearing material composition. This makes these joists the ultimate product to ensure your decking project has a solid sturdy foundation.
Due to the recycled plastic construction, these joists are also ideal for submerged applications such as pontoons or decked areas above water. Use our board screws to ensure there is no splitting.
Our composite joists can be used with any type of decking construction, from diagonal and custom designs to standard square and rectangular layouts. Take a look at our installation guide for more details.
