Tapered built up frames
Welded plate columns and rafters, tapered to follow the bending moment. Depths and plate thicknesses are set per building.
Product range
What we manufacture, across all three systems.
Manufactured, not merchanted
We make what we sell
Every product below is formed, welded or assembled in our own works. That matters more than it sounds: it means the section sizes can be matched to your building rather than your building being fitted around whatever sections are in stock.
It also means one accountable supplier for the frame, the envelope and the accessories, on one order and one delivery schedule.
Structural
Primary and secondary steel
Z and C purlins
Cold formed secondary members carrying roof and wall sheeting between frames. Depth and gauge follow the span and load.
Eave struts and girts
Secondary framing that stiffens the envelope and carries wall cladding.
Bracing and tie rods
Rod, angle or portal bracing sized for the wind and seismic case at your site.
Light gauge sections
Roll formed studs, tracks, joists and trusses for LGS structures, cut and punched to the drawing.
Mezzanine and racking steel
Beams, columns and decking for intermediate floors and storage systems.
Before it ships
Primed, marked and ready to bolt
Members leave the shop cut to length, drilled, welded and primed. Nothing is cut or fitted on site, which is what keeps erection to a sequence rather than a problem.

What we need to confirm for you
Product specifications are issued per project. These are the questions our estimators answer once we know the application.
| Item | Confirmed against |
|---|---|
| Section sizes and depths | Span, spacing and the governing load case |
| Steel grade | The design code applying at your site |
| Gauge or plate thickness | Load, span and durability requirement |
| Coating and finish | Exposure conditions and required service life |
| Connection type | Bolted as standard; welded where the detail requires it |
| Tolerances and testing | The inspection regime agreed for the project |

SCIP panels
Structural concrete insulated panels
An SCIP panel is a super insulated core of rigid expanded polystyrene held between two layers of welded steel wire mesh. Galvanised steel truss wires are pierced right through the core at offset angles for strength and welded to both layers of mesh.
Once the panels are erected, openings are cut, reinforcement is added and the walls and roof are concreted and plastered, giving solid, insulated buildings with a finish similar to conventional construction.
- Hurricane and earthquake protection, up to 7.5 on the Richter scale
- Energy savings of 50 to 80 percent
- Heat and sound insulation, and termite proof
- Lower maintenance cost, environmentally friendly
- Additional floors can be added

How it goes up
SCIP installation
Delivery and erection
Panels are delivered to site and stood in position.
Openings and reinforcement
Windows and doors are cut, and structural reinforcement is added.
Roof panels and services
Roof panels and their reinforcement are laid, with conduit and piping run inside.
Slab and concrete
The roof is shuttered for the slab and the walls are concreted.
Plaster and finish
The structure is plastered and handed over finished.
