Initially named Auerbach \& Werner, combining the names of its German-origin owners: engineer Paul Werner and blacksmith Ernst Auerbach. The company expanded and incorporated steel into its production line, changing its name to Electro Aço Altona in 1933\. Thus emerged Santa Catarina's first steel foundry and one of Brazil's earliest. Over the past decade, the company has acquired other businesses to accommodate and expand its production lines, as well as established overseas subsidiaries to better serve customers in key commercial markets such as Europe and North America. Altona continues progressing steadily, consistently identifying high-growth economic sectors to expand its reach, develop new markets, and deliver steel solutions across diverse industries.
