SeAH Steel Holdings Corporation SeAH Steel Holdings Corporation (003030.KS) serves as the holding company for the steel pipe manufacturing operations of the SeAH Group, overseeing the production and global distribution of specialized steel products including carbon welded steel pipes, stainless welded steel pipes, titanium tubes, steel pipes for offshore wind substructures, galvanized color steel sheets, and heavy-wall pipes for oil and gas applications; these products support industries such as construction, shipbuilding, LNG infrastructure, plant projects, oil and gas extraction, and offshore foundations. The company operates production facilities in South Korea at Pohang, Suncheon, Changwon, and Gunsan, with additional international plants in the United States, Indonesia, UAE, and through affiliates in Europe and Asia, targeting domestic Korean markets alongside exports to Japan, China, Vietnam, the United States, and the Middle East. Founded in 1960 and headquartered in Seoul, South Korea, SeAH Steel Holdings emerged from a 2018 corporate spin-off of the former SeAH Steel Corporation, separating holding functions for foreign affiliates from core domestic manufacturing now managed by SeAH Steel. Recent strategic developments include a January 2025 offtake agreement with Almonty Industries for 100% of molybdenum output from the Sangdong project to bolster alloy production; multi-billion won investments in 2024-2025 by affiliates such as SeAH Changwon Special Steel into a U.S. special alloy plant targeting aerospace, defense, and SpaceX supply chains; acquisition of redeemable preferred shares in a Saudi Arabian joint venture with Aramco; and expansion of UK-based SeAH Wind facilities for offshore wind infrastructure, alongside certifications like the 2024 hydrogen embrittlement test for advanced steel pipes.
