Quality Assurance – von Schaewen

Comprehensive in-house destructive and non-destructive testing

Quality is our primary concern which is why we test our products in our own in-house laboratory by ourselves. Here we scrutinize them according to international standards and customer-specific requirements.

Highly qualified staff

Our highly qualified staff measures work pieces as well as constructions and determines their mechanical and technical properties by means of our certified testing facilities.

Meeting all customer requirements and standards is top priority for our specially trained employees and they support the manufacturing process on each and every step from production to dispatching, taking aspects of quality into consideration.

Certifications according to DNV-GL, LR, ABS, BV, RMRS, DGRL and AD 2000

We have these strict quality requirements we dedicate ourselves to every day regularly checked and approved by external and independent audits. Our numerous certifications of all leading institutes prove that we surely meet high standards which we also safeguard sustainably by means of a certified quality management. Therefore, our customers can rely on economic processes, best products and clear, verifiable and electronically archived documentations
