The purchasing strategy of the ZKW Group is a key building block in our corporate planning. We see the best possible supplier management as a central challenge, and a reliable supply chain as essential to the current and future success of our company.

We maintain long-term business relationships built on trust with our existing suppliers, relationships that include close cooperation with an eye toward product development. We are actively engaged in supplier development in certain segments – particularly in areas where ZKW is opening up new markets.
