Steel Joist System
Steel Joist System
Rollforming Services manufactures the SPEEDFLOOR® Steel Joist System, an engineered solution which offers extended spanning capability (up to 6.5m in residential flooring) and unmatched constructional flexibility in almost any type of construction.
The galvanised C sections feature unique fold-out ‘tab’ connectors in the perimeter channel for fast and accurate joining. There is also the option of pre-punched holes for fast, efficient installation of services.
Assembled onsite or delivered as a pre-assembled cassette, SPEEDFLOOR® joists are easily configured for mezzanine floors, portal framed sheds, industrial platforms, residential mid floors and piled sub floors or integrated into timber framed buildings.
