When INTERSTAHL Service GmbH was founded on January 2nd 1990 it was impossible to foresee what it would develop into. The idea of INTERSTAHL was and still is to support our customers with a wide portfolio of services. We recognized the fast changing markets especially in the steel sector and are always searching for adequate solutions for our business partners that support their business strategy and allow for as much flexibility as possible. Supporting our service is a strong ethical foundation of fairness and trust.

We take the expansion and continued renewal of our knowledge about steel very seriously, always looking for opportunities to increase our expertise.
