Overview
About Otto Klostermann GmbH
Who we are
Otto Klostermann GmbH is a family-run company that was founded in 1848 as a forge by Otto Klostermann. In 1945, the company was taken over by Raymund Klostermann and expanded by Raymund Klostermann in 1969 and moved to the new location at Merklinderstraße 5 in Castrop-Rauxel. This created more space for the forge and the development of sheet metal processing and cold forming technology. In 1986, Thomas Klostermann became co-managing director. Today, Philipp Klostermann and his sister Marie Klostermann-Vogel run the company in the 6th generation. Our services in the areas of metal processing and processing are accordingly extensive. We offer laser cutting, plasma cutting and autogenous cutting and are also an absolute specialist in the field of forming technology.
