Companhia Siderúrgica Nacional engages in the production of steel in Brazil and Latin America. The company’s annual crude steel capacity and rolled product capacity at the Presidente Vargas Steelworks is 5.6 million and 5.1 million tons, respectively. It also operates in the mining, cement, logistics and energy businesses. Segments Steel This segment’s fully integrated manufacturing facilities at the Presidente Vargas Steelworks produce a line of steel products, including slabs, hot- and cold-rolled, galvanized and tin mill products for the distribution, packaging, automotive, home appliance and construction industries. The company’s production process is based on the integrated steelworks concept. Slabs: The company produces high, medium and low carbon slabs, as well as micro-alloyed, ultra-low-carbon and interstitial free slabs. Hot-Rolled Products: The company provides coils of heavy gauge hot-rolled sheet having a maximum thickness of 12.70 millimeters used to manufacture automobile parts, pipes, mechanical construction and other products. It produces light gauge hot-rolled coils and sheets with a minimum thickness of 1.20 millimeters, which are used for welded pipe and tubing, automobile parts, gas containers, compressor bodies and light cold-formed shapes, channels and profiles for the construction industry. Cold-Rolled Products: The company supplies cold-rolled coils in thicknesses of between 0.30 millimeters and 2.99 millimeters. Galvanized Products: Galvanized products can be used to manufacture a range of products, such as bodies for automobiles, trucks and buses; manufactured products for the construction industry, such as panels for roofing and siding, dry wall and roofing support frames, doors, windows, fences and light structural components; air ducts and parts for hot air, ventilation and cooling systems; culverts, garbage containers and other receptacles; storage tanks, grain bins and agricultural equipment; panels and sign panels; and pre-painted parts. The company produces galvanized sheets and coils in continuous hot-dip processing lines, with thickness ranging from 0.30 millimeters to 3.00 millimeters. In addition to standard galvanized products, it produces Galvanew, galvanized steel that is subject to a special annealing process following the hot-dip coating process. At CSN Paraná, one of the company’s branches, it produces galvalume, a cold-rolled material coated with a zinc-aluminum alloy. Through its branch CSN Paraná, it also produces pre-painted flat steel, which is manufactured in a continuous coating line. Tin Mill Products: There are four types of tin mill products, all produced by the company in coil and sheet forms: tin plate - coated on one or both sides with a thin metallic tin layer plus a chromium oxide layer, covered with a protective oil film; tin free steel - coated on both sides with a very thin metallic chromium layer plus a chromium oxide layer, covered with a protective oil film; low tin coated steel - coated on both sides with a thin metallic tin layer plus a thicker chromium oxide layer, covered with a protective oil film; and black plate - uncoated product used as the starting material for the coated tin mill products. Tin mill products are primarily used to make cans and other containers.
