We have been certified according to DIN ISO 9001 since 1993.

The quality management system is continuously being improved and is an essential component of our company structure. It is integrated into the work of the entire staff as part of their daily work. The service of the quality management systems is evaluated annually by the management.

The transition of quality management to the NEW ISO 9001/2000 standard has been carried out at 2003.

The quality management system, the environmental management system, the safety management system and the risk management system are all mapped in an integrated system.
