VTN Witten Annen

We have been using steel on site since 1873. Since 2001, the historical walls have contained a VTN facility with maximum performance for protective gas processes. At the heart of the site is a fully automated multi-purpose chamber furnace line in 24-hour operation. The range of services is supplemented by pit furnace technology and a continuous belt furnace.

The experienced team primarily looks after customers from the automotive industry and sophisticated mechanical engineering, with a focus on safety-relevant products for brakes, chassis parts or steering gears.
