SteelX Rebar
Twisted Steel Reinforcement — TSR

Stronger concrete. Fewer weeks. Safer sites.

SteelX 5:25 gives you stronger concrete, a shorter program and a safer work site — twisted steel reinforcement that replaces mesh and conventional rebar across slabs, footings, walls and shotcrete.

What is SteelX

Twisted steel rebar. Not steel fibre.

Every strand bonds to the concrete matrix over its full length and must untwist to pull out. That single difference is what lets engineers design with it like rebar — and what takes the mesh, the cages and the weeks off your site.

Bond
Torsional anchorage
The twist engages before the concrete fails, creating a true composite with the matrix. Pullout is untwisting, not friction.
Behaviour
Proactive, then stable
It improves the concrete before a crack forms, then holds a stable capacity after — so it can be designed like rebar, not guessed at.
Outcome
Steel off your site
Remove mesh and rebar, cut pavement thickness, delete steel fixing, deliveries and set-down areas. Shorter program, safer site.

SteelX Liberty™ Slab

Freedom from joints

The SteelX Liberty™ jointless slab system removes the need for saw-cut joints while reducing slab thickness by 20%. Construction joints are governed by what can safely be poured and finished — not by restraint or typical joint spacing.

◆No saw-cut joints, no joint sealing
◆20% thinner slab on ground
◆Controlled, tightly spaced crack widths
◆Easy to pump, easy to finish
◆Less maintenance, next-level durability
◆Standard mesh sizes — SL62 to SL92

On-site dosing & QA

Dosed at the truck. Every truck on record.

We dose SteelX into each truck on site with a fibre blower — at the specified kg/m³, in front of your crew. Every load is logged in QA McClay, so you can prove what went in to your engineer, certifier or client years after handover. Available across South East Queensland.

How on-site dosing works →
01
Matched to each load
The dose is set by each truck's volume, not by counting bags.
02
Any supplier
The batch plant doesn't need to stock or handle SteelX.
03
On record
A per-truck record for your engineer, certifier and project file.
