About EEW Group
EEW Group is a German family-owned company headquartered in Erndtebrück, specializing in the manufacture of large-diameter longitudinally welded steel pipes and prefabricated pipe components. The product range includes monopiles, piles and tubes for jacket components for the offshore wind industry, as well as line pipes, process pipes, clad pipes, tubes for cryogenic applications and buckle arrestors for the oil and gas industry. The company evolved from the forge Erndtebrücker Eisen- und Blechwaren GmbH, founded in 1936, into pipe manufacturing in the mid-1970s. Today EEW produces at sites in Germany (Erndtebrück, Rostock), South Korea (Sacheon, Gwangyang) and Malaysia (Pasir Gudang). Its products contribute to the expansion of the global energy supply, in particular the construction of offshore wind installations.
