Laboratory Testing Facilities

Accredited test laboratories for a consistent quality

We carry out chemical, mechanical and metallographic tests in our accredited test laboratories. Swiss Steel AG ensures a continual improvement in the individual departments due to the continuous feedback of process and test data to the process. Quality Assurance provides proof of the process quality through the accompanying inspections, which are mostly performed in the central test laboratories.

The key areas of our labs are accredited (STS0026) according to ISO/IEC 17025. The current scope of accreditation includes mechanical tests, metallography and spectrometry. The sample preparation departement mechanical produces various types of samples in conformity with standards or customer specifications.  The test and measuring equipment monitoring department manages all the test and measuring equipment (gauges, micrometers, etc.) at the production site in Emmenbrücke as well as for various external customers.

Our laboratories with their modern facilities are available for analyses and tests commissioned by external customers.
