Quality management

Quality is our promise. The art of combining modern design, easy handling and intrinsically lasting quality has been GREINER’s claim since 1922. GREINER's modern quality management accompanies every step of the process. Whether in planning, development, toolmaking or assembly - we guarantee you precision.


In accordance with our quality management, the zero-defect principle guarantees that our customers receive well thought-out products that convince through durability, high-quality components and hard-wearing covers. These high standards are ensured by modern measuring instruments and automated processes. The quality management system of GREINER is certified according to EN ISO 9001 and EN ISO 13485 and with regard to the approval-relevant requirements (GRA) of international and German road traffic law (KBA).

However, despite all automation, technical processes at GREINER can never replace the trained eye of our experienced employees. We remain particularly proud of this. This quality promise makes the fine difference for demanding customers.
