Hot Rolled China Steel

- 1 -

1. Brief Introduction China Steel CorporationCSCwas established in December 1971 and started its production in December 1977. After four stages of consecutive expansion, the annual production capacity of crude steel has reached

11.5 million metric tons. The major products include steel plates, steel bars, wire rods, hot-rolled coils,

cold-rolled coils, coated coils, electrical steel coils, and electro-galvanized coils. All of these products are

widely used in various downstream manufacturing industry for enhancing competitiveness and forming a

mutual beneficial interdependence between the CSC and customers. CSC proved it to be a reliable and

innovated supplier of steel products. The accreditation certificate of ISO 9001, ISO/TS 16949, IECQ, ELV, the Taiwan Accreditation FoundationTAFand JIS MARK approvals were obtained to demonstrate CSC's commitment to keep progressing in quality management system.

Providing cost-effective and superior quality of products and services to diversities satisfied customer is the

original mission of CSC. The company has therefore put a great deal of effort in expanding and modernizing

its facilities, and continually improving the products quality and developing new products as well to help

customers to create more value-added products. The newly developed hot rolled steel products such as CSC

HC1085, CSC HM-690T, CSC HC 15B22, ASTM A572 GR.50 TYPE 1, JFS A1001 JSH590Y, JFS A1001

JSH780R and API 5L X52M PSL2 were introduced to meet the stringent market demands.
