Certifications and licenses

With over 90 years of industry experience, we understand the enormous importance of professional quality management.

We outwardly underline our commitment to this by comprehensive certification of our management systems at regular intervals. We are convinced that good quality assurance not only guarantees satisfied customers, but also generates high employee satisfaction. Together, these create a solid foundation for sustainable business success.

The effectiveness of the systems we have installed is checked and secured by regular verification and validation supported by concrete, measurable targets. Constant dialogue with all parties involved in the provision of services enables continuous revision and upgrading of existing systems and more strongly sensibilises them to proficiency in their assigned tasks and all associated responsibilities.
