Dual-listed steel group Vulcan said it signed a conditional deal to buy Australasia's Ullrich Aluminium for $165 million.
Vulcan said the deal would be fully debt-funded.
Ullrich is a large integrated distributor of industrial aluminium products in Australasia with a big sales network, together with extrusion facilities and fabrication operations.
In the financial years ended March 2021 and 2022, Ullrich recorded $215m and $270m in revenue, respectively, and $32m and $49m in EBITDA.
Vulcan managing director and chief executive Rhys Jones said Vulcan had had its eyes on the aluminium sector for some time.
