In June 2009, the certification of our quality management system for the production according to ISO 9001:2008 by TÜV Rheinland successfully completed. An extensive examination of the quality management process, the processes and the management went ahead. "The certification makes our system more transparent for customers and complies with the external audit by the expectations of our customers for an objective yardstick." so Rocco Weyers, CEO of G.W.P. AG. "Ensuring the quality of internationally comparable criteria, the acceptance of our services continue to increase production."
