Structural fabrication

We are specialists in structural fabrication and welding. Our skilled team can fabricate steel and aluminium to comply with Australian structural standards (AS/NZS 1554 and 1664).

For peace of mind, our structural welding can be independently verified by National Association of Testing Authorities (NATA) certified inspectors. This rigorous laboratory testing process can all but eliminate the possibility of structural weld defects.
