Companhia Siderúrgica Nacional

Companhia Siderúrgica Nacional (CSN) operates as a leading integrated steel enterprise with significant presence in Brazil and throughout Latin America. Its diversified business model encompasses five primary divisions: Steel production, Mining, Logistics, Energy generation, and Cement manufacturing. Within its steel segment, CSN delivers a comprehensive range of flat steel products. These include slabs with varying carbon compositions (high, medium, low, micro-alloyed, ultra-low-carbon, and interstitial-free), alongside heavy and light-gauge hot-rolled coils and sheets, and cold-rolled coils and sheets. The company also supplies galvanized steel, tin mill products (comprising flat-rolled, low-carbon steel coils or sheets), and structural elements like profiles, channels, UPE sections, and steel sleepers. These materials cater to diverse industries such as packaging, automotive, home appliance, construction, and general distribution. CSN's mining operations involve the extraction of iron ore from its Casa de Pedra and Engenho mines situated near Congonhas, and limestone and dolomite from the Bocaina mine in Arcos, Minas Gerais. The company is also engaged in tin production. Supporting these activities, CSN maintains and operates its own railway and port infrastructure for efficient logistics, and generates its electrical power via thermoelectric co-generation and hydroelectric plants. Furthermore, its cement division manufactures and distributes cement to a wide array of clients, including building material retailers, home improvement centers, concrete manufacturers, construction firms, and producers of mortar and cement artifacts. CSN also extends its market reach through international product exports. Founded in 1941 and based in São Paulo, Brazil, Companhia Siderúrgica Nacional is a subsidiary of Vicunha Aços S.A.
