A Perfect Pour, Floor After Floor

SPEEDFLOOR® Suspended Concrete Flooring is one of the lightest suspended concrete floor systems available in the market, incorporating a unique composite floor of steel and concrete, which makes light work of pouring anything from single-level, to multi-level structures. The galvanised steel joists are easy to assemble and light enough to be positioned by hand. There is no propping required - simply assemble the joists, add structural supports and you are ready to pour. Floors can typically achieve composite action in 72 hours. 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 transporting to site with no propping or painting required. Slabs can be 90mm to 220mm in thickness. Minimum compressive strength of 25mPa to achieve composite action is normally achieved within the first 72 hours of curing, depending on environmental conditions.

Advantages of Suspended Concrete Flooring

Advantages of Suspended Concrete Flooring

Before you pour any concrete, let us pour over what you want in a suspended concrete floor, and why choosing SPEEDFLOOR® Suspended Concrete Flooring is a good call.

1. Fast and easy to install
Time is money, so a fast and easy installation matters. SPEEDFLOOR’s® steel joists are simple to assemble and the poured floor does not require propping.

2. Lightweight, less materials
Over an equivalent span, the SPEEDFLOOR® system uses less materials – the use of secondary steel is reduced (subject to structural requirements), compared with other approaches. The joists can be manually positioned, reducing the need for cranage.

3. Cost-effective
When a flooring system is fast to install and uses less materials, it is more cost-effective – especially when labour and material costs are rising.

4. Environmentally Responsible
Reducing the steel and concrete in your flooring is not just cost-effective, it is environmentally responsible as well.

5. Smart integration of services
Positioning services can be a headache. SPEEDFLOOR® Suspended Concrete Flooring steel joists provide pre-punched holes for services to pass through to make your life easy.

6. Building standards
SPEEDFLOOR® Suspended Concrete Flooring meets all the applicable standards and codes, plus it can be fire rated.

Structural 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.

PROJECT EXAMPLES

EMA carpark ready for future growth

When the EMA (Employers and Manufacturers Association) decided to expand their Auckland EMA Employment Hub, they recognised they may need to expand again in the future.

That is why their new five-story carpark had consent for another two stories, and why the engineers and architects chose to specify SPEEDFLOOR® Suspended Concrete Flooring.

Not only did this ensure a fast, cost-effective build today, but those additional floors can be added tomorrow with minimal disruption.

Downtown Carpark adds levels without hassles

To see how easy it is to add levels to a carpark with Speedfloor® Suspended Concrete Flooring you do not have to look far.

When Auckland’s Downtown Carpark underwent an expansion, the team there added two new levels while the carpark continued to operate.

The joists were easy to transport into location and assemble, the floor could be poured without propping, and other work could continue without further interruption.

FAQs

There are a number of methods to fire rate the SPEEDFLOOR® joist some of which are:

  • Fire rated ceiling
  • Cementatious coating
  • SPM method

Your local SPEEDFLOOR® Franchise can help you with the selection as the different situations can require a different approach.

The SPM program is available from HERA. The program is easy to use and if you use the inputs set in the SPEEDFLOOR® design manual then a confirmation that the selected fire rating period will be achieved. Alternatively if you send structural plans to your local SPEEDFLOOR® Franchise, we will run the program and send the confirmation back to you.
