POSCO-Thainox Public Company Limited (POSCO-Thainox), Thailand’s only manufacturer and distributor of premium cold-rolled stainless steel sheets and coils, was founded on 30 July 1990 as a joint venture of the world’s leading steel industry groups from France (Arcelor), Japan (Nippon Steel), and Thailand (Mr. Prayudh Mahagitsiri). On 20 September 2011, POSCO, Global Steel and Stainless Steel Maker acquired Thainox.

Since its establishment, POSCO-Thainox has increased its domestic and global market share considerably at an annual compounded growth rate of 20%. The company supplies 60% of its premium-quality stainless steel products for applications in various industries within the country, and exports 40% of its output to more than 30 countries across the globe through the strong networks.

Currently, POSCO-Thainox possesses an annual production capacity of 200,000 tons which is expanding to 300,000 tons in an attempt to better serve the company’s existing customer base as well as support its growth and rising demands for stainless steel consumption.
