To ensure optimum product quality for our customers, we constantly review our raw materials, compounds and processes. Every step in the production process is monitored and each batch is tested for standard and order-specific parameters

In addition to the certifications of our operating and quality management system according to DIN EN ISO 9001, our lining materials for corrosion and wear protection, for example, are also equipped with various test marks, including the DIBt building approval and the food safety confirmed by the Ruhr District Institute of Hygiene.

Modern Efficiency Characterizes the WAGU Processes

Through a strict, process-oriented approach and a continuous improvement process, we permanently increase the efficiency of internal processes.

In addition, we continue to develop our certified energy management system in line with our processes. WAGU's integrated management system also complies with current environmental protection and risk management standards. Together with a certified process auditor, we also ensure that the requirements of the International Automotive Task Force (IATF) are implemented in our processes and constantly monitored and optimized.

On request, we will gladly assist you with the certification of your products.
