In the year 2000 Salzgitter AG acquired Mannesmannröhren-Werke and established the Tubes Division of the Salzgitter Group. Since 2014, the pipe and tube producing companies comprise the Group’s Mannesmann Business Unit.
The name of Mannesmann has been a byword for the highest quality steel tubes for over a century.
In 1885 the brothers Reinhard and Max Mannesmann filed a patent application for the world’s first rolling process for manufacturing seamless tubes. Their invention revolutionized the piping, engineering and vehicle construction industries. At the end of the 1890s Mannesmann also began production of welded steel tubes.
