Why Steel
The Smarter, Stronger Choice
100% Termite Proof
WA has some of Australia's most aggressive termites. Steel is completely immune — no chemical treatments, ever.
Fire Resistant
Non-combustible steel does not ignite or feed a fire — ideal for bushfire-prone WA sites and BAL compliance.
Cost Effective
Faster installation, less waste and zero maintenance. No swelling, no warping, no call-backs.
Sustainable
Steel is the world's most recycled material — high recycled content and 100% recyclable at end of life.
Peace of Mind

the people inside
Steel doesn’t burn, warp, rot or feed termites. A Trueline frame stands straight and true for the life of the home – so the families who live inside stay safe, comfortable and worry-free for generations.
