Speedfloor Systems

A high precision, concrete composite floor with integrated, cold-formed, pre-galvanised steel joists for superior strength and accuracy. Visit the Speedfloor website for more information.

Get in Touch


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. Manufactured from galvanised, high strength steel in a one pass roll-former, the frame is light enough to be manhandled into place for pouring. The ends are simply bolted to the joists which are then ready for transport to site with no propping or painting required. 

Slabs can be 90mm to 220mm in thickness. Minimum compressive strength of 25 mPa to achieve composite action is normally achieved within the first 72 hours of curing, depending on environmental conditions.

  • Requires no propping.
  • Reduces use of secondary steel, subject to structural requirements.
  • Joists can be manually positioned, reducing the need for cranage.
  • Provides a safe working platform during construction.
  • Services can pass through the pre-punched holes in the joist.

Span vs Load Calculator

  • As part of the complete design solution, a Suspended Concrete Floor load vs span calculator is available to designers and specifiers. Visit the Speedfloor website to access this calculator for free.
  • The Speedfloor Suspended Concrete Flooring conforms to Australian and New Zealand building standards.

Structural Standards

The Suspended Concrete Flooring meets Australian and NZ composite structural standards and the NZ Building Code standards for fire and acoustic performance.

The suspended slab can be fire rated by applying the SPM method developed by Heavy Engineering Research Association (HERA) without additional treatment of the steel joists or fire-rated plasterboard ceilings.
