Mannesmann is a leading global network for steel tube technologies. Together with Salzgitter AG, we develop and produce highly specialised precision, line and large-diameter tubes for the most demanding industrial applications. Our particular strength lies in our technological depth: from material development and customised production processes to our own testing and research expertise. Our extremely resilient steel tubes are key technologies for climate protection and the energy transition - they are used in wind turbines or hydrogen infrastructures, for example, and are already perfectly adapted to the challenges of tomorrow's grids.
