Quality needs action and concepts. At proroll, we are not satisfied with pithy slogans about our product quality. We give our best every day, constantly reassessing our processes and our products. Modern testing machines and a well thought-out test design are important components of proroll's QA management. In our laboratory, test series for various product groups run continuously - always with the aim of verifying the test results of our suppliers, updating older data or determining the properties of our own developments. With our own long-term tests, we map the life cycle of various products in order to generate reliable results. Once tested is good... endurance tested is even better
