Integrated Business Model


CSN is one of the largest mining companies in the country. The Minas Gerais plants produce ore with high iron content, supplying the steelmaking activities of the company and exporting to various countries.


The Presidente Vargas Steelworks (RJ) focuses CSN‘s steel production, with a capacity of 5.6 million tons per year. The Porto Real (RJ) and Araucaria (PR) plants make products for the automotive industry and major appliances, respectively. As the largest steel supplier for packaging throughout the Americas, CSN produces and sells steel for the manufacture of packaging for various market segments, being the only national producer of tinplates.


The shares CSN has in two hydroelectric plants (Ita and Igarapava) and the thermoelectric plant in Volta Redonda ensures the energy self-sufficiency of the company, driving all other businesses.


Iron ore is transported by rail to the Presidente Vargas Steelworks – for steel production – and to Tecar in the Port of Itaguaí, from where it is exported to several countries. Trains also carry inputs for steel production.


Slag from steel production is used in the manufacture of cement, bringing huge gains in synergy between activities. In Arcos, CSN has a clinker plant, another raw material for cement.


In 2001, CSN began its internationalization process with the acquisition of the assets of Heartland Steel (which constitute CSN LLC, in the United States. Five years later, CSN acquired 100% of Lusosider in Portugal – a steel mill in which it had a participation of 50% since 2003. In 2012, the company took another important step when it bought the German steelwork StahlwerkThüringen GmbH (SWT).

Quality and environment management systems are certified, respectively, by standards ISO 9001 and ISO 14001.
