What about the cost to transport assembled wall frames & roof trusses over large distances to northern West Australia due to the volume of space they occupy?

This can be eliminated with our system of steel wall frames & trusses, as the smartsteel roll former produces each individual piece of steel by labeling it, cutting it exactly to size, punching all holes and counter sinking screw fixing locations, to give a flush finish. Which means the entire house frames walls & roof can be shipped unassembled in strapped smaller bundles occupying a lot smaller truck space and assembled on site by your local builder using supplied manuals.
