The decades of consistently high quality products have always represented one of the key factors in LEONI’s success, and this remains the case. We pay special attention to quality in our precise planning, testing and documentation systems.

Our quality management adheres strictly to the requirements of ISO 9001 and ISO 14001. We are proud that our railway cables are acknowledged by the world's major railway vehicle manufacturers (Siemens, Bombardier, Hyundai Rotem, CSR, Alstom, Stadler etc.) and are already used in a number of projects.

In order to fulfil the high quality requirements of our customers for years to come, our extensive production facilities are equipped with state-of-the-art machinery. This applies in every area, from plastics production, materials processing and extrusion processing to electron beam irradiation. Not only do our products meet all the current national and international standards and regulations, they also set the standard for top-quality cable manufacturing.
