Bisalloy Steels

What Bisalloy Steels does

Bisalloy Steels (ASX:BIS) is an Australian manufacturer of quenched and tempered steel plate, headquartered in Unanderra (Illawarra region), New South Wales, and operating since 1980 as Australia's first producer of this specialised steel category. The company manufactures a portfolio of plate products under the BISALLOY brand, including Wear Steel for abrasion resistance in mining and earthmoving, Structural Steel for weight-saving construction and transport applications, Armour Steel for ballistic protection, Protection Steel for security applications, and the recently launched Q700D grade for transport structures. Its core technology is a proprietary quenching and tempering heat treatment process that produces plate certified to international standards including ISO 9001, ISO 14001, ISO 45001, and military specifications MIL-S-21952 and T9074-BD-GIB-010/0300.

The company generates revenue through a hybrid go-to-market model combining a distributor network (Southern Steel, Infrabuild, United Steel) for reach into industrial and fabrication customers across Australia and Asia, with direct enterprise field sales for defence and government customers. Bisalloy serves seven primary customer segments — mining and earthmoving, mineral processing, defence, agriculture, construction, engineering and fabrication, and protection — with manufacturing concentrated at its Wollongong facility and regional distribution operations in China, Indonesia, and Thailand. Its defence franchise is anchored by longstanding relationships with the Australian Defence Forces and German Defence, and has been materially strengthened by qualification as the only Australian producer of HY80 submarine-grade steel, evidenced by a first purchase order from General Dynamics Electric Boat for US Navy Virginia-class submarines. The company is expanding into adjacent digital services through its Bisalloy Digital wear monitoring platform and into the European market via CE Marking certification and a strategic partnership with MIRAS. FY2025 revenue was approximately A$152.8M with EBITDA of A$30.9M and net income of A$19.6M, indicating margin expansion despite flat top-line performance over the prior three fiscal years.
