Suspended Concrete Flooring

Speedfloor is a suspended concrete floor system using a cold formed steel joist as an integral part of the final concrete and steel composite floor. The joist is manufactured from pre-galvanised high strength steel in a one pass rollformer giving a high degree of accuracy at a fast production rate. The ends are simply bolted to the joists which are then ready for transport to site. No Propping, No Painting, No Hassles
Steel Joist Systems Transportable Concrete Floor


The Speedfloor concrete floor system is a proven performer in all types of construction, from steel structures, masonry buildings, poured in-situ or pre- cast concrete panels, to ICF, timber and cold formed steel frame construction.


  • The Speedfloor system requires no propping.
  • Speedfloor slabs are generally only 100mm thick, reducing weight and providing savings through- out the structure.
  • The lightweight joists are able to be manually positioned requiring less cranage.
  • During construction Speedfloor provides a safe working platform.
  • Services can pass through the pre-punched holes in the joist.


As part of the complete design solution, a load versus span calculator is available to designers and specifiers.

  • Speedfloor cold formed joists are manufactured from high strength, pre-galvanised steel.
  • The concrete slab is designed to have a minimum compressive strength of 25MPa after 28 days.
  • The design of the floor system conforms to Australian and New Zealand composite structural standards.
  • The design of the floor system conforms to Australian and New Zealand composite structural standards.


Speedfloor’s acoustic performance meets Building Code design criteria and is supported by an independent report available on request.


Full scale fire tests have established that the Speedfloor system can be fire rated and meets fire rating requirements set out in the Building Codes.

A design procedure involving the addition of in-slab reinforcement can be used for slabs exposed to moderate and severe fire conditions. The procedure is based on quantifying the tensile membrane enhancement provided by in- slab reinforcement.
