Quality management 

Thanks to the high quality of our products, we have gained national and international acceptance from our customers for over 45 years, achieved competitive advantages and secured our company's success.

In order to guarantee the continuity of our quality, we work with a consistently practiced QM system based on DIN ISO 9001 and 9120.


We have also been supplying products to the aerospace and defense industries for over 30 years. Initially only with semi-finished products, today as a service provider for semi-finished products and blanks. Due to the high-quality requirements of the aerospace industry, a functioning quality management system is indispensable. In this area, we are certified by TÜV Nord in accordance with EN 9120.


The employees of our company are of particular importance. Through active suggestions for improvement, the use of state-of-the-art machinery and targeted training programs, we produce and supply high-quality products for almost all industrial sectors and the aviation industry at home and abroad on a daily basis.

We also consider it extremely important to maintain close contact with our customers and suppliers. Direct contact serves to promote, future-orientate and improve cooperation under the umbrella of quality.
