USIMINAS - Usinas Siderurgicas de Minas Gerais S.A., is the leading company of the Usiminas System, the largest flat steel complex in Latin America. The System posted a consolidated net revenue of R$ 13.8 billion in 2007 and had production capacity of 9.5 million tons of crude steel per year on the two plants - Ipatinga (in the Minas Gerais state) and Cubatao (in the Sao Paulo state), which accounts for over 25% of the Brazilian production and a 52% share in the domestic flat rolled market. The permanent focus on sustainability, which drives its strategy and actions, led Usiminas to acquire, in February 2008, one of the largest iron ore assets in the southeastern region of Brazil and control all of the steel production chain -- from ore mining through the processing of products.
