QUALITY HAS TO BE SAFE.

QUALITY ASSURANCE
Our quality assurance is based on our ISO 9001:2015 certification. All processes and tests are managed and documented in accordance with this standard. Continuous, consistently documented quality controls throughout the entire production cycle of a stainless steel tank are an absolute must in order to meet the sometimes extremely high requirements of our long-standing international customers.
Another important quality component of our high-quality stainless steel containers is the ongoing training of our engineers, technicians, and skilled workers. In addition to our own high quality goals and customer requirements, constant monitoring by independent bodies such as TÜV Süd, TÜV Chemie Service, or TÜV Nord is part of everyday life at BOLZ-EDEL. This independent monitoring applies in particular to our welding processes and all pressure vessels.
