In order to guarantee a high standard of quality for all manufactured parts, we produce under an approved and controlled system.

Cooperating manufactures, suppliers and ib-s too, have been working consequently this way since 1997. In 2001 we introduced the new DIN-Standard EN ISO 9001:2000.

Our selected manufactures have first-class certificates such as VDA 6.1 or QS 9000.

through our customer Deutsche Bahn AG, we receive an anual supplier evaluation.
