Wall Framing
Light, perfectly aligned and precision-engineered wall frames.
Every stud is roll-formed to exact length, so there is no packing, planing or straightening on site. Frames are pre-braced in the factory for flush walls and pre-punched with service holes for faster electrical and plumbing rough-in.

Floor Joists
Lightweight, incredibly strong and cost-effective floor systems.
Our LGS joists are made to order from 200 mm to 600 mm deep and span up to 8 metres. Their high strength-to-weight ratio reduces internal load-bearing walls and columns, giving you more open, flexible floor plans.

Structural Steel
Heavy steel that integrates seamlessly with our light gauge frames.
Custom fabrication, in-house welding and engineering support mean heavy and light steel are designed together, with tight tolerances, coordinated deliveries and faster assembly on site.

Residential Frames
Complete steel house frames, built from the ground up.
Floor joists, wall frames, roof trusses, facades and balustrades for everything from compact homes and townhouses to boutique villas and multi-storey apartments. Fire-resistant, termite-proof and stable for decades.
From drawing to standing frame
One team handles engineering, manufacturing and delivery, so every stud, joist and truss arrives ready to fit.
Consult & quote
Share your architectural drawings or concept. We review scope, loads, budget and timeline, then send a clear quotation.
Design & engineering
Our engineers model the entire frame in 3D, check it structurally and produce shop details for every member.
Precision manufacturing
Automated roll-formers turn G550 coil into labelled, pre-punched members, assembled into panels and trusses under ISO 9001:2015.
Delivery & installation
Frames are packed by assembly sequence and delivered to site. Screw-fixed connections mean fast, clean installation with no welding.
