Composite Decking Joists
Specifically engineered to support composite decking boards, the joists provide a durable, low-maintenance subframe that is designed to perform in all weather conditions.
Tough Decking Joists can be easily installed by either screwing directly into place using decking screws or by haunching into position
Once installed, the composite decking boards can be fitted directly on top for a clean, future proof finish and install
For best results, they should always be laid on a solid, level sub-base with a slight gradient to allow effective water drainage.
Key Benefits Include:
- Strong and durable composite construction

- Similar expansion and contraction properties to composite decking boards
