We operate a state-of-the-art integrated steel mill in Sepetiba Bay in the Brazilian state of Rio de Janeiro. Our products are high-quality steel slabs, which are processed in the ThyssenKrupp Group’s European and US plants. Our mill – opened in June 2010 – will produce five million metric tons of steel per year when fully ramped up.
