RFPI Joist Design

Interactive I-Joist Span Tables

As architects/designers are creatively designing their structures, it can be hard to understand how our products will perform for the span and condition they end up in. We have created a quick and interactive span reference tool to give the answers to these questions fast and without having to open any span chart books.

We also understand the value of optimised design solutions so we offer a range of permanent deflection criteria’s to evaluate in conjunction with Max joist spacings, standard house and or domestic unit floor loads and let’s not forget standard lightweight loads (carpet and vinyl) vs direct stick floor tiles.
