The SJ255 set-down joist creates a 45mm step in the floor; whether it’s just for the shower enclosure, or for an entire wet area. The SJ255’s high strength web and long spans allow greater design flexibility for builders than ever before. Like all other SmartJoists, we can provide pre-cut penetrations in the SJ255 for plumbing and other services.

The SJ255 set-down joist allows builders to easily provide a set-down and screed detail where they want to continue tiles across a floor into the wet area. Previous approaches to set-down wet areas using timber I-Joists were complicated and relatively expensive (lots of brackets, blocking etc). The SJ255 simplifies assembly and is more economical, so a superior bathroom finish can be achieved with easy assembly of the floor structure, and lower cost.
