California Steel Industries (CSI) is committed to reaching high levels of productivity and quality. CSI began operations in 1984, and since then $1 billion has been invested in our facilities to maintain, modernize and add operations. We are the only West Coast steel supplier manufacturing five different product lines: hot rolled, pickled and oiled, galvanized and cold rolled sheet, and electric resistance welded pipe. In most of our product groups, we have the broadest production capabilities on the West Coast. We compete with other western U.S. steel manufacturers, domestic suppliers from east of the Rocky Mountains, and with imported steel from around the world. Our success in this competitive arena is proven by our ability to continue to increase sales and production year after year.
