We know the international market and purchase raw materials from around the world according to clearly defined quality criteria. In addition to the storage and end finishing in Germany, we are increasingly carrying out production, processing and finishing abroad, particularly in China. Our high-quality expectations apply to their full extent when it comes to products and production conditions there as well.

An extensive quality assurance system keeps the quality at the very highest level starting at the beginning; from the receipt of goods right up to the final shipment of the finished products.
