Uncompromising QualityUncompromising Quality
What defines us is the uncompromising quality paired with our employees’ in-depth knowledge. Some of our employees have been working with us over generations in their families, giving this company its unique competitive edge: Industry experience right back to the very invention of the seamless stainless steel tube.
Non-destructive Testing All of our products run through several testing stages during production. Eddy current and ultrasonic tests are our methods to provide for optimal quality.
Certificates
We are certified according to all relevant standards and qualifications and keep those certificates updated permanently.
QHSE Protection of the environment and of natural resources are important corporate goals for us. The compliance with all valid legislation and regulations is a matter of course. We always go one step further, however, as our understanding of responsible environmental protection does not end with compliance with statutory regulations.
