Quality

As GSB and QC certified companies from the very beginning, our surfaces and processes are constantly subjected to all common and required (and beyond) test procedures. This is one of the reasons why we are now always able to back your orders with long-term guarantees. All processes in the corporate group are consistently integrated via a management system in accordance with ISO 9001:2015.
 
We are very proud that we have not had a significant complaint in our long history.
