THE AUSTRALIAN STEEL COMPANY (OPERATIONS) PTY LTD

InfraBuild Steel (formerly OneSteel Limited) is Australia's largest vertically integrated steel manufacturer, recycler, and distributor, with operations spanning scrap metal recycling, primary steel manufacturing, and nationwide downstream distribution. The company operates multiple NATA-accredited testing laboratories across Australia, including facilities at Sunshine (Victoria), Newcastle (New South Wales), and Geelong (Victoria), which provide materials characterization and mechanical testing services to external clients on a conditional basis.

The company's testing capabilities are centered on mechanical testing and materials characterization of steel products in accordance with Australian and New Zealand standards. InfraBuild's NATA-accredited laboratories perform tensile testing, hardness testing, Charpy impact testing, and other mechanical property evaluations following AS1391 (Mechanical testing of metals) and AS/NZS 3679 series standards for structural steel products. These laboratories issue NATA-endorsed test certificates and Certificates of Compliance for welded products, supporting both internal quality assurance and external client requirements.

InfraBuild serves the construction, infrastructure, mining, and primary production industries throughout Australia. The company operates over 150 steel centres and distribution points nationwide, making it the primary supplier of reinforcing steel, structural steel, and steel long products to commercial and residential construction projects, as well as infrastructure and mining operations. The company is particularly focused on sustainable steel manufacturing, with initiatives including the SENSE 600® lower-embodied-carbon reinforcing steel and Environmental Product Declarations (EPDs) independently verified for lifecycle and environmental impact transparency.

The company maintains comprehensive quality management systems, including ISO 9001 Quality Management System accreditation and ISO 14001 Environmental Management System accreditation across all manufacturing sites. InfraBuild operates NATA-accredited steelmaking and mechanical testing laboratories (NATA accreditation numbers include 1726 for steelmaking and 1843 for mechanical testing), with individual site accreditations dating back to 1970 at the Newcastle and Sunshine facilities. These quality systems and accreditations ensure consistent testing methodology and reliable characterization of steel materials for compliance verification and product qualification.

Key testing locations include the Sunshine Laboratory (NATA No. 862, established 1970) in Victoria, the Newcastle Laboratory (NATA No. 821, established 1970) in New South Wales, and the Geelong Wire Mill Laboratory (NATA No. 1237, established 1976) in Victoria.
