POSCO (NYSE:PKX) (NYSE: PKX) is a South Korea–based integrated steel producer founded in 1968 as Pohang Iron and Steel Company. Headquartered in Pohang, the company grew rapidly as part of South Korea’s industrialization program and developed large, integrated steelworks—most notably in Pohang and Gwangyang—that helped establish POSCO among the world’s largest steelmakers. It is structured as a diversified industrial group with steelmaking at its core and a range of downstream and trading businesses.
The company’s primary activities include ironmaking and steelmaking, producing a wide array of steel products such as hot-rolled and cold-rolled sheets, coated steels, plates, stainless and special steels, long products (bars and wire rods), and seamless pipes. POSCO supplies these materials to major end markets including automotive, shipbuilding, construction, home appliances and industrial machinery. Through subsidiaries and affiliates, it also offers engineering and construction services, trading and supply chain solutions, and downstream processing to support customers’ manufacturing needs.
POSCO serves customers globally, exporting steel products and operating sales and service networks across Asia, Europe, the Americas and other regions. In recent years the company has expanded beyond traditional steelmaking into higher-value and growth areas such as battery materials for electric vehicles, advanced alloys and components, and initiatives aimed at reducing carbon emissions—including low‑carbon steelmaking technologies and hydrogen-related projects—to align with changing market demand and regulatory trends.
As a publicly listed company, POSCO combines large-scale manufacturing capability with investments in research, technological development and supply-chain integration. Its strategic focus emphasizes product quality, vertical integration, and transitioning toward more sustainable and diversified revenue streams while maintaining its role as a major global supplier of steel and steel-related products.
