Nippon Steel Corporation
NS-Siam United Steel Co., Ltd. (NS-SUS; President: Hideki Ogawa), a consolidated subsidiary of Nippon Steel Corporation (Nippon Steel) and a manufacturer of cold-rolled steel, hot-dip galvanized and galvannealed steel sheets, and tinplate steel in Thailand, has decided to invest approximately 2 billion baht (about 8.9 billion yen) to expand the capacity of its electric plating line (EPL), aiming to meet the growing demand from customers, particularly can manufacturers, for tinplate steel used in containers.
Since 1963, when Nippon Steel began establishing product processing bases in Thailand, the country has been one of the most important strategic markets in the company’s overseas business strategy. Nippon Steel Group currently operates 30 local companies in Thailand, both directly and indirectly, including G/GJ Steel, which it acquired in 2022 with a total investment of approximately 17.9 billion baht (78.8 billion yen). The company has created around 8,000 jobs and contributed to the development of Thai industry by building a comprehensive supply chain from steel production to end users in the country.
Thailand is a major export base for food cans, with the industry concentrated there. Both the demand and market for container tinplate steel are expected to continue growing and expanding steadily. NS-SUS has recently decided to make a capital investment to increase its container tinplate steel supply capacity, aiming to further promote domestic production in Thailand and contribute to strengthening and developing the supply chain there. As a result, NS-SUS will increase its tinplate steel production capacity from the current 280,000 tons per year to 350,000 tons per year, with the capital investment for this expansion scheduled for completion in March 2027.
