Decking Joist C24 - Treated to UC4 47x150 4.8m

We stock pressure treated, sturdy 47x100mm (2" x 4") joists. We carefully select our decking joists, rails and supports to ensure they offer the stability you need when enhancing an outdoor space.

Keep the spacings between your joists to no more than 450mm (18 inches) - or your decking boards may "bounce" when you walk on them.

Do not forget to include the "noggins" - the cross members designed to keep your deck stable and secure. If your joists are 450mm apart - try to put a noggin every 1500mm (5 feet)
