ThyssenKrupp Rothe Erde

Founded in Dortmund in 1855 as Paulinenhütte, Rothe Erde initially manufactured railway axles, wheels and other equipment. In 1861, Aachen industrialist Carl Ruetz acquired the works and established the name Rothe Erde Dortmund.

After becoming part of Vereinigte Stahlwerke in 1926, the company was re-established as Eisenwerk Rothe Erde GmbH in 1934, expanding into the production of large slewing bearings. Following severe wartime destruction, reconstruction began in 1949.

Integration into the Hoesch Group in 1966 marked a new technological era. In 1967, a modern ring-rolling mill was established in Dortmund, enabling the production of seamless, large-diameter steel rings. Following the Krupp takeover of Hoesch in 1993, Rothe Erde joined ThyssenKrupp in 1999.

Today, advanced rolling, machining and heat-treatment technologies enable Dortmund to manufacture seamless rings up to eight metres in diameter.
