About the company
California Steel Industries, Inc. (CSI) is a major flat-rolled steel manufacturer in Fontana, California, serving customers throughout the Western United States. The company operates a large integrated steel plant on approximately 430 acres, with about 115 acres under roof. CSI produces hot-rolled, pickled and oiled, cold-rolled, galvanized and galvannealed sheet products, along with electric-resistance-welded pipe. The company began operations in 1984 and has invested heavily in expanding and modernizing its facilities. CSI’s products serve commercial construction, agriculture, HVAC, automotive-related applications, gas and oil pipelines, and other industrial markets. Its production processes include steel rolling, finishing, coating, quality control, engineering, and metallurgical support. The Fontana operation is a direct steel mill rather than a distributor, making it a strong fit for Steel Manufacturing. CSI describes itself as the leading producer of flat-rolled steel in the Western United States and maintains a substantial domestic workforce and industrial production footprint.
