Union Corporation

Established in 1964 and headquartered in Seoul, South Korea, Union Corporation plays a significant role in the nation's cement sector. The enterprise, which adopted its current name in July 1977 after previously operating as Union White Cement Co., Ltd., offers a diverse range of construction materials. These encompass building supplies like white Portland cement, products for tile work, plastering and masonry items, flooring solutions, waterproofing and repellent agents, and various additives. The company also furnishes refractory materials such as calcium aluminate cement and aggregates, alongside civil engineering products including repair and reinforcing components, and specialized tunnel and underground construction materials. Furthermore, Union Corporation extends its operations into environmental technologies, providing filtering devices—including filter and screw presses, unifilters, fiber filters, and nonpoint pollution reduction equipment—as well as ozone systems. A final facet of its business involves the reclamation of metals, notably vanadium and molybdenum.
