We employ the Speedfloor Steel Joist system which offers extended spanning capability 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.
Speedfloor cold formed joists are manufactured from high strength, pre-galvanised steel coil conforming to AS 1397. The minimum mass coating of galvanising is 275g/m2. The standard steel used is grade 250 and has a minimum yield stress of 250MPa and a minimum tensile stress of 280MPa.
Span tables are available on request and are published in the Speedfloor Steel Joist System Product Manual which can be downloaded from the Speedfloor website.
