Only quality will stand the test of time

Quality requires the perfect blend of ability, passion and total focus on customers. A quality management system provides the framework for this. Naturally, that means one that is certified and regularly updated. You can read more about GRENKE’s certifications and awards here.

ISO 9001:2015-certified Quality Management System

GRENKE’s quality management processes have been certified to the ISO 9001 standard since 1998. We keep our improvement processes going with training and internal information sessions. Regular audits and re-certification by our certification partner, TÜV Süd, ensure that our quality management system is always up to date.
