Overview
China Steel Corporation (CSC) was founded in 1971, the largest steel manufacturer in Taiwan, headquartered in Kaohsiung. It mainly produces steel plates, bars, wire rods, etc., supplying domestic and international markets, and is an important pillar of Taiwan's heavy industry.
History
China Steel Corporation emerged from Taiwan's industrial planning during the 1960s. The proposed company was intended to create a domestic integrated steelmaking capability capable of supplying the island's expanding industrial economy. CSC was formally established on December 3, 1971. Its first head office was in Taipei, but the company relocated its headquarters to Kaohsiung on September 15, 1975, as the main steelworks was built in the southern port city. Construction of the steel mill began with the first stage on November 1, 1974. The first blast furnace was brought into operation on June 27, 1977, and the initial construction program was completed later that year. The second and third development stages were completed in 1982 and 1988. These expansions established the basic scale and integration of the Kaohsiung works, which later operated four blast furnaces. The facility combined ironmaking, steelmaking, continuous casting, rolling, and finishing operations in a single industrial system. CSC adopted continuous casting at an early stage and later computerized important production processes. Continuous casting reduced the need for certain intermediate steps and supported more efficient conversion of molten steel into semi-finished products. Process automation and computerization helped improve operating control and product consistency, allowing CSC to compete in international steel markets as well as serve Taiwanese manufacturers. The company's ownership structure changed substantially. CSC began as a non-governmental company, became state-owned on July 1, 1977, and was re-privatized on April 12, 1995. Its legal status is now non-governmental, but the Taiwanese government remains a major shareholder and continues to influence corporate governance. The company is the principal entity in the CSC Group, which includes affiliated businesses connected with steel, materials, engineering, logistics, and related industrial activities. Through its integrated works and group structure, CSC became a core supplier for Taiwan's downstream manufacturing economy. Its products support construction, transport equipment, machinery, appliances, energy projects, and other heavy industrial uses. The company also sells outside Taiwan and has developed international commercial and investment relationships. A 2016 industry comparison cited by the reference material ranked CSC as the world's 23rd-largest steel producer. Environmental performance has become an increasingly important part of the company's operating context. Integrated blast-furnace steelmaking is energy intensive and produces substantial direct and indirect greenhouse-gas emissions. CSC reported total direct and indirect emissions of 19.579 million tonnes of carbon-dioxide equivalent for the year ending December 31, 2020, representing a reported reduction from the previous year. The company therefore operates within the broader steel industry's ongoing transition toward greater efficiency, emissions control, and lower-carbon production.

Products and positioning
An integrated, export-capable steelmaker positioned as a foundational supplier to Taiwan's manufacturing, construction, transportation, energy, and infrastructure sectors.
Semi-finished steel
Steel slabs
Slabs are semi-finished cast steel products used as feedstock for rolling operations. They form an important intermediate stage between steelmaking and the production of flat steel for industrial customers.
Flat steel
Hot-rolled steel
Hot-rolled products are made by reducing heated slabs through rolling mills. They are used directly in applications where surface finish and tight cold-rolling tolerances are less critical, and they also serve as input material for further processing.
Flat steel
Cold-rolled steel
Cold-rolled steel is further processed from hot-rolled feedstock to achieve more controlled thickness, surface quality, and mechanical performance. It is used in manufacturing sectors such as appliances, transportation equipment, machinery, and fabricated products.
Finished flat steel
Coated steel
Coated steels receive a protective or functional surface treatment designed to improve corrosion resistance, appearance, or suitability for downstream forming and fabrication. These products extend CSC's offering beyond basic rolled steel.
Specialty steel
Electrical steel
Electrical steel is engineered for magnetic applications and is used in electrical equipment such as motors, generators, and transformers. It represents a higher-specification product area within the company's broader steel portfolio.
Long steel
Bars and wire rods
Bars and wire rods are long steel products supplied for fabrication, construction, fasteners, machinery, and other downstream industrial uses. Their production complements CSC's flat-steel operations.
