Description
Produced from recycled plastics and measuring 4000mm x 100mm x 50mm, the structural composite joists are available in charcoal colour only.
Ideally placed onto a concrete base underneath, these structural composite decking joists will ensure that everything is correctly positioned and crucially give a strong foundation for your project.
Installation Notes
These joists have been specifically designed with durability in mind. For optimal strength and reliability, we recommend purchasing one structural composite joist for every square metre of decking, with a maximum spacing of 400mm between each joist. To ensure correct installation, please refer to the installation guides.
It's important to note that these structural joists require support every 1m. When installing composite decking onto our structural joists, we advise a maximum of 400mm centres. For PVC decking installations, we advise 300mm centres. With our Decking Joist Support, you can trust that your deck will be both sturdy and safe.
The colour of your joists does not need to match the rest of your installation as they will be installed within the foundations and can be hidden with decking and fascia boards.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

Garden Storage
My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.

Right product, right price, right delivery.
Right product, right price, right delivery. Sure, it was only one length of cast iron guttering but they took the order seriously, packed it well and kept me updated on delivery. And when I opened the very good packaging I found it was exactly what I had wanted. How can you do better!!
