Five ways SteelX takes steel off site
Every project below is real, with the dosage and the slab spec that was actually poured. Filter by what you’re building.
The Liberty™ Slab. All saw cut joints removed and 20% off the thickness, using 18 kg/m³ SteelX 5:25 with conventional mesh.
Mesh replaced outright on jointed designs, using the tensile resistance method from CCAA T48. No cutting, tying, chairs or cover risk.
Mesh stays, bar goes — or the layers come down. Where a slab still needs mesh for its design, SteelX removes the bar and the doubled-up layers around it.
Cages gone from strip footings, pad footings, pile caps and bored piers. Dig and pour, with steel kept only at peak stress.
Crack widths held below 0.10 mm — the AS 3735 watertightness threshold — so membranes and tanking come off the job entirely.
Project reference index
28 SteelX projects, as poured. Dosages, mesh and thicknesses are the real numbers.
Liberty Slab — 150 mm thick. Originally specified as a post-tension slab, changed to a SteelX Liberty Slab with SL92 mesh and 18 kg/m³ SteelX 5:25. No joints and no visible cracks.
Jointless topping slab — 29 m × 21 m, 70–120 mm thick. Fully restrained by edge beam with SL72 mesh, 18 kg/m³ SteelX 5:25 and E5 Internal Cure. Not a single visible crack — reported by engineer.
31 m × 17 m unrestrained freezer slab with SL82 mesh and 18 kg/m³ SteelX 5:25. No joints and no visible cracks — critical for hygiene in cold storage environments.
235 mm thick — 33 m × 21 m slab with large pits and full edge restraint. 23 kg/m³ SteelX 5:25 with one layer SL81 mesh bottom. Built by Hutchinson Builders. Replaced a conventional 290 mm design with N16-200 bottom + N12-200 top. No joints and no visible cracks.
Liberty Slab — 400 mm thick, 33 m × 12 m. SL102 mesh top and bottom with N12-500 in the long direction and 18 kg/m³ SteelX 5:25. Designed for heavy mine equipment.
Liberty Slab — 150 mm thick, 26 m × 9.5 m. SL72 mesh with N12-500 in the long direction, 18 kg/m³ SteelX 5:25 and E5 Internal Cure. No joints and no cracks.
Liberty Slab — 160 mm thick. Two restrained slabs: 33 m × 32 m and 33 m × 12 m. SL102 mesh with 18 kg/m³ SteelX 5:25 and E5 Internal Cure. Crack free slabs.
200 mm Liberty Slab — 20 m × 22 m. 18 kg/m³ SteelX 5:25 + SL81 mesh. Replaced 35 kg/m³ double hook end fibre. Multiple projects completed 2023 and 2025.
Five house slabs with all internal beams removed. 230 mm reduced to 180 mm. 18 kg/m³ SteelX 5:25 + SL92 mesh with E5 Internal Cure. Zero cracking.
Flat plate slab design with no internal beams. 140 mm / 32 MPa. 14 kg/m³ SteelX 5:25 + SL82 central. Crack free house slabs — fully restrained.
12 causeway slabs, 170 mm thick, reduced from 200 mm. 12 kg/m³ SteelX 5:25 replaced two layers of SL82 mesh. E5 Internal Cure replaced curing compound. Eliminated the concrete pump.
150 mm / 32 MPa jointed design. 8 kg/m³ SteelX 5:25 replaced SL82 mesh.
External pavement, 170 mm / 32 MPa. 8 kg/m³ SteelX 5:25 replaced SL92 mesh. Jointed design with a perfect broom finish.
150 / 200 / 250 mm industrial pavement. 8 kg/m³ SteelX 5:25 replaced SL102 mesh. Poured over summer at +37°C, cured with E5 Internal Cure.
200 mm slab thickened for racking loads. 15 kg/m³ SteelX 5:25 replaced two layers of SL92 mesh. Cured with E5 Internal Cure.
5,000 m² / 160 mm industrial slab. 14 kg/m³ SteelX 8:45, cured with E5 Internal Cure. Poured in summer without a roof — no cracking.
175 mm thick culvert apron. 18 kg/m³ SteelX 5:25 + SL82 mesh replaced N12-150 each way.
Heavy load workshop. 220 mm slab / 50 MPa. 12 kg/m³ SteelX 5:25 + two layers of SL92 with E5 Internal Cure.
Early entry heavy traffic slabs, 200 mm thick. 18 kg/m³ SteelX 5:25 + SL92 mesh with E5 Internal Cure. Opened in two days, 16 m joint centres.
Strip footings with 20 kg/m³ SteelX 5:25. All conventional steel eliminated. Easy pumping.
Bored piers with 20 kg/m³ SteelX 5:25 + 1N20. Strip footings with 20 kg/m³ SteelX 5:25. Pile caps with 20 kg/m³ SteelX 5:25 + SL102 top and bottom.
580 m³ poured in one night at 20 kg/m³ SteelX 5:25, all pumped. Steel used only at areas of peak stress.
25 MPa bored piers. 15 kg/m³ SteelX 5:25 + 1N24 bar. Steel cage eliminated.
10 kg/m³ SteelX 5:25. Cage eliminated.
20 kg/m³ SteelX 5:25. Cage eliminated — dig and pour.
20 kg/m³ SteelX 8:45. Removed all other steel.
Trafficable membrane removed. 30 kg/m³ SteelX 5:25 to control crack widths below 0.10 mm, with E5 Waterproofing dosed at Mansell Premix.
