We say: "Every employee works for quality management".

Service quality has top-ranking for us both externally and internally. We work on it every day: with clear organisation and clear competencies, in quality groups, at training courses, in further education, certifications and audits, and with modern software and statistical methods for the systematic analysis of weak spots.

We deploy independent quality controllers. In addition, we have a central international quality controller and controllers in every country and at every branch location.

Depending on the requirement profile, our companies and plants are certificated according to DIN EN ISO 9001:2000, ISO 14001, TS 16949, SQAS and also in accordance with other internationally valid standards.

We control our partners constantly - for we only cooperate long-term with companies that fulfil our quality requirements.
