Pre-fabed wall frames and roof trusses for the easiest of construction

Why Use Steel

Strong, durable and precision engineered

Our steel frames are safer, stronger and more secure than other framing solutions. Every pre-fabed piece possesses a unique strength – each piece attaches using components then bolts to the slab or screws to an elevated floor. 

100% termite-proof

Truecore steel frames are 100% termite-proof… no ifs, buts or maybes. When it comes to termite resistance in your home there is no safer option than steel framing


Truecore steel frames incorporated into our homes have the potential to save you thousands of dollars in maintenance and chemical termite treatments. 

Truecore goes in straight and stays straight

Our steel frames are precision engineered to be dimensionally accurate – they will not shrink, twist or warp and provide a solid and true surface for plasterboard. 

Non combustable

Unlike other building materials, a house frame made from TRUECORE® steel is non-combustible and will not ignite.

50 year warranty

TRUECORE® steel is durable and strong, protected by a 50 year warranty from BlueScope
