Certificates

StS-Coupling is certified according to DIN ISO 9001-2015.

The international standard for quality management ISO 9001, which has been revised since 2012, was published in September 2015 as ISO 9001: 2015 and replaces version 9001: 2008. StS Coupling GmbH adapts to the new guidelines and was successfully re-certified with the new standard in December 2016. We were successfully recertified in May 2023.

Every delivery leaves our company only after a thorough quality control. In this way we guarantee consistent quality at the highest level. This is confirmed to us through annual certifications from an independent certification body.
