History
Votorantim Siderurgia was created in 2008 as the steel platform of Votorantim Group, a Brazilian conglomerate with activities in several industrial sectors. At launch, the steel business had around 5,300 employees, operations in Brazil, Argentina, and Colombia, and installed capacity of approximately 2.45 million tonnes per year. The platform brought together established and newly acquired assets. Its oldest mill was Barra Mansa in Rio de Janeiro State, Brazil, whose industrial history extended back to 1937. Votorantim had acquired Acerías Paz del Río in Colombia and AcerBrag in Argentina in 2007. These acquisitions expanded the company's presence beyond Brazil and gave it a regional base in long-steel production. Votorantim also invested in new Brazilian capacity. A steel plant built at Resende, Rio de Janeiro State, began operating in September 2009. The facility was designed with annual capacity of approximately 1.03 million tonnes of long steel. Together with the existing plants, the project strengthened Votorantim's position in construction-related and other long-steel markets. The company's scope extended beyond steel mills. It operated or participated in iron-ore and coal mining and developed and managed forest plantations used to produce charcoal. Charcoal was used in the production of pig iron, an important intermediate raw material for steelmaking. These activities gave the business a degree of vertical integration from natural resources through primary steel production. Votorantim Siderurgia also held 13% of the voting shares of Usiminas, providing exposure to another important Brazilian steel producer. The holding complemented its directly controlled operations and reflected the group's broader participation in the country's steel industry. A major strategic change was announced in February 2017, when ArcelorMittal and Votorantim disclosed plans to combine their Brazilian long-steel operations. The planned arrangement made Votorantim Siderurgia a subsidiary of ArcelorMittal Brasil. The available source describes this transaction but does not provide enough information to determine the subsequent legal identity, brand usage, asset transfers, or whether Votorantim Siderurgia continued as a separately presented business. Its present status therefore remains unclear in this dossier.
