Ribbed Slab Systems

We have an extensive range of precast, pre-stressed, slab systems which provide a fast, cost effective and simple solution for any suspended slab requirement. 

Project specific slab designs are created using an optimised combination of pre-stressed slab beams in conjunction with our infill options. 

The system achieves full composite action with slab depths of 190mm to 400mm possible and beam centres ranging from 480mm up to 1470mm. 

Our pre-stressed beam range has been developed and continuously refined over the last two decades.

All beams are produced using a specially designed 65 MPa concrete mix and are pre-stressed with 9.5mm low-relaxation steel strands under the strictest ISO 9001 quality controlled conditions.

Slab Beam Range

We have three beam ranges which are denoted by their widths ~ R-Beams (130mm), M-Beams (190mm) and C-Beams (250mm).

Fibre Cement Reinforced infill

Fibre cement reinforced infill has been purpose made for the Ultrafloor system. The standard widths are 400, 500 and 600mm. View a Fibre  Cement infill  section

Metal Deck infill

Metal deck is used with our C & M-Beam ranges and allows for beam spacings of up to 1470mm. Standard widths are 660, 965 and 1270mm. View a Metal Deck infill section  


Setdown clips & Duragal angles   : Support the infill sheets for full depth slab sections.

Setdown & Multi formers: Create thickenings for structural, fire & acoustic detailing.   

Steel beams and saddles  : Custom beams designed to span across any void.
