Standard & Compliance

Steel Building Systems Australia endeavours to produce steel frames of the utmost quality and safety. In doing so, the steel frame design assessment is based on the requirements within the Australian Standards (AS), the Building Code of Australia (BCA) and the National Association of Steel-Framed Housing (NASH) Standards.

Australian Standards

The Australian Standards adhered to are:

  • AS/NZS 4600, Cold formed steel structures
  • AS 3623, Domestic metal framing
  • AS 4100, Steel structures


The BCA standards adhered to are:

  • BCA Volume 2, Part 3.4.2 Steel Framing
  • BCA Volume 2, Part 3.1.3 Termite Risk Management


Supaloc steel frames follow the NASH Standards for Residential and Low-Rise Steel Framing. These standards set structural adequacy and serviceability requirements of the design criteria for steel-framed structures including houses and other low-rise residential and commercial buildings. They enable structural engineers to create efficient and economical steel framing systems while complying to stringent safety regulations.

Engineering Standards

The Supaloc steel building system includes the provision of certification by a third party qualified engineer. Most local government authorities will require the submission of framing drawings as part of the building approval process. In some circumstances, council and/or private building certifiers will allow provisional building approval to be granted on the submission of a certification letter prepared on behalf of Supaloc Steel Building Systems by its third party certifying engineer.

All Supaloc products are certified by a Chartered Professional and Independent Technical Expert within the meaning of Regulation 85 of the Development Act, 1993. The assessment is based on the requirements of the Australian Standards and other documents listed as reference documents to the Building Code of Australia. Based on Supaloc Steel Building System test results, standard section data, and the engineer’s check calculations, each project is built in accordance with the provisions for strength, stiffness and serviceability as required by Part B of the building Code of Australia.


Supaloc steel frames are built to the highest safety standards as outlined by the Building Code of Australia, the National Association of Steel-Framed Housing and the Australian Standards. Our steel frames also undergo vigorous testing to ensure maximum safety and reliability. The materials themselves are first tested in the BlueScope facilities in Pt Kembla to ensure a quality initial product that can withstand the harsh Australian climate. The steel frame structure then undergoes further scrutiny in our in-house testing facilities including a hydraulic push/pull test rig and an air-bag test bed for wind load testing of walls.
