Sustainable corporate management includes not only stable customer relationships, but also sustainable relationships with suppliers. We have maintained long-term partnerships with our suppliers as equals for decades and offer them a high degree of reliability that has proven itself in our business relationships. Thanks to these good relationships, for example, we were always able to supply our customers even during the Covid crisis, which led to major problems in global supply chains. The supply of raw materials was ensured thanks to long-standing and solid supplier relationships.
