About Trueline Steel
Western Australia’s trusted supplier of prefabricated steel framing
Who We Are
Trueline Steel is a Perth-based supplier of high-quality prefabricated steel framing products for residential, commercial, rural, and industrial construction.
We supply directly to builders, contractors, and developers across Western Australia — providing dimensionally accurate, galvanized steel frames that arrive on site ready to install. Every product we supply is manufactured to Australian Standards (AS1397) and engineered to perform in WA’s tough climate conditions.
Trueline Steel imports and supplies steel framing direct — cutting out local-manufacture markups to give WA builders a faster, more cost-competitive alternative to timber framing, without compromising on certification or quality.

Every frame we supply is manufactured to AS/NZS 4600 and AS 3623, ensuring structural integrity and precision.
On-Time Delivery
We understand construction timelines. Our supply chain is designed to get frames to your site when you need them.
Builder-First Service
We work directly with builders and contractors — clear communication, accurate quotes, and reliable support throughout your project.
Built for Western Australia
Our steel framing solutions are engineered for WA’s climate — termite zones, cyclone ratings, bushfire areas, and coastal environments.
