Reaching the goal together

From the purchase of zinc ingots to the acquisition of company cars, from chemicals to office supplies – every year we purchase a wide range of products and services for GRILLO. Our purchasing department is an important interface within the company and an important point of contact for our suppliers. It ensures that procurement at all locations is based on uniform and comprehensible criteria.

At GRILLO, we attach great importance to working in partnership and cooperative relationships with our suppliers. In addition to quality and cost aspects, we also attach great importance to sustainability criteria.

  • Collegial and professional cooperation
