Why Steel

The Smarter, Stronger
Choice for WA.

More WA builders are making the switch to steel framing. Here’s why steel consistently outperforms timber across every major building category.

Steel vs. Timber

The Facts

100% Termite Proof
Western Australia has some of Australia's most aggressive termite populations. Steel frames are completely immune — no chemical treatments, no re-inspections, no call-backs.
Fire Resistant
Steel does not ignite or contribute fuel to a fire. Our frames meet BAL ratings for bushfire attack levels, making them the preferred choice in fire-prone areas.
Cost Effective
While the upfront material cost is comparable to hardwood, steel frames reduce total project cost through faster installation, less waste, and zero maintenance.
Environmentally Friendly
Steel is the world's most recycled material. Our frames contain up to 40% recycled content and are 100% recyclable at end of life.
Precision Manufacturing

Straight, True &
Dimensionally Accurate

One of the biggest complaints builders have with timber is inconsistency — bowed studs, twisted plates, and oversized crown. With Trueline Steel, every frame member is CNC-precision cut to exact dimensions.

The result: plumb walls, level floors, and faster lining. Your trades will thank you.
