What are Joists?

When laying decking it's important to have a solid foundation - that's where joists come in! Decking joists are beams used to create a framework to lay decking on. Here at DeckPlus we provide a range of composite decking joists in various dimensions, so that you have all the tools you need to create the perfect deck!

Composite decking joists are more reliable than alternative timber joists because composite joists are resistant to damp, rot, and warping. Composite decking joists are guaranteed to stand the test of time, even when exposed to inclement weather!
