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

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