Qualitymanagement at WSW

Quality is the foundation of all activities at WSW.  That means that each employee has to contribute to fulfil the customers’ expectations, based on the WSW Quality policy: Zero-defect quality for products, processes and services is a prerequisite for securing the future. Therefore, our first priority is to completely satisfy our customers by means of faultless products and services, deliveries exactly on schedule as well as competent and friendly cooperation between our employees and customers.



In addition to our own certification according to DIN EN ISO 9001:2008 our suppliers also have to be certified. Furthermore, quality reports are obligatory for each delivery of material as well as regular tests of our products from leading German Universities and Institutes.
