Mannesmann Grossrohr GmbH
Mannesmann Grossrohr GmbH is a wholly owned subsidiary of Salzgitter AG and has been manufacturing spiral-welded large-diameter pipes for the most demanding applications in the gas, oil and water transport industries in Salzgitter / Lower Saxony for over 60 years. Within our group of companies, we develop and optimise new steels and technologies together with our sister companies Salzgitter Flachstahl GmbH and Salzgitter Mannesmann Forschung GmbH in order to be able to meet the high demands and individual requirements of our customers at all times. In recent years, we have already been able to supply international and national projects, including the connection pipelines for the German LNG terminals, with pipes that already meet the requirements for the transport of hydrogen.
