Thanks Rigo and Luke at Steel Frames W.A. Nothing was ever too much trouble. Communication was excellent, and they consistently went above and beyond to keep my project running smoothly and on track.The only improvement I can think of is if Steel Frames W.A. somehow cloned them.

We have used SFWA, and the product itself was excellent. We were happy with the quality and overall performance and the team were very helpful during the modelling stage.The installation team that completed the trusses and frames did a fantastic job and were great to work with. The project coordination could have been better, as there were a few delays during the installation process.

Super ! So glad I went with them, easy experience. Even after delivery these guys have been super helpful. As an owner builder I would highly recommend to others ! We installed it all ourselves. The install was simple and well put together, very clear. Comes with bracing on the frames already. Just super happy with the whole experience. Thankyou team!

Very professional and responsive, great communication. From the yard to office staff, everyone were very helpful. Highly recommended!
It was a pleasure working with a professional team at Steel Frames WA. All our expectations were met. The quality and durability of the steel frames and trusses are beyond compare. We have since found the structures on a smaller scale for other projects very useful and we were gladly accommodated.

As customer of Steel Frames WA, I can comment firsthand, that they provide excellent service, design, and manufacturing. Their finished product is second to none, with very strong and rigid frames which are precision built enabling one to have millimetre accuracy onsite. Also, their factory-built frames enable a quick and efficient build, saving a lot of time and expense. I can highly recommend Steel Frames WA and believe they are setting the benchmark for this industry in WA.

FAQs

Steel offers exceptional strength without heavy weight, so it supports an additional storey while placing minimal load on your existing structure. It does not warp, shrink or bow—and it is non-combustible and termite-proof, giving you long-term peace of mind.

Absolutely. Steel is highly recyclable, and prefabrication cuts down waste on site. That makes steel framing a more sustainable choice—and one that leaves a lighter footprint without compromising strength.

Yes—it’s one of steel’s standout benefits. Whether you want open-plan living, large windows, or unusual layouts, steel’s precision and flexibility allow us to tailor your addition exactly to your vision.

Steel handles extreme weather very well. Its strength and rigidity make it ideal in high winds or storms—and unlike timber, it remains dimensionally stable in temperature extremes.

Western Australian weather can be harsh—but steel thrives here. It resists termites, fire and moisture. And when built to current Australian standards, it stands up to our sun, heat and occasional storms with ease.

We support you end to end. That means design using advanced software, supply, prefabrication with pre-braced and pre-punched components, and full installation. We also handle the crucial connections between your new upper level and existing home—so everything meshes together securely.

It is easy to begin. Get in touch with our friendly team, share your ideas and site details, and we’ll guide you through design options, structural engineering, pricing estimates, and scheduling. From there, you can move confidently into planning and construction.
