SeAH Steel Corporation (306200) manufactures energy, structural, and piping steel pipe products, and is a listed affiliate majority-owned by SeAH Steel Holdings, which holds roughly 63.59% of shares.
Its core products include oil country tubular goods (OCTG), line pipe, structural pipe and piping materials, and stainless welded pipe, produced at domestic plants including Suncheon and Pohang.
Its largest end market is the US oil and gas sector, supplied through its US sales subsidiary SeAH Steel America (SSA), and the company's exposure to US exports is reportedly high relative to other Korean steelmakers.
More recently, the company has been expanding into higher value-added, energy-transition products such as pipe for offshore wind foundations and stainless pipe for LNG and CCUS (carbon capture, utilization and storage) applications.
Its Suncheon plant houses what is described as the largest domestic roll-forming 24-inch stainless pipe line, giving it capacity to produce large-diameter pipe for LNG applications.
In the Middle East, the company has built a track record through its API pipe plant in Ras Al Khaimah, UAE, completed in 2011, supplying projects ordered by affiliates of Abu Dhabi National Oil Company (ADNOC), and it recently signed a contract to supply roughly 1,750 tons of stainless pipe to a UK government-led CCUS project in Teesside.
Domestically, NexTeel, Husteel, and Daehan Steel are cited as comparable listed peers in the pipe business, and the company also competes with large overseas OCTG suppliers, with pricing power heavily dependent on product specifications, certifications, and local production and supply networks.
