Needs Overview

Welcome to Purchasing!

Together with our suppliers, we are responsible for ensuring that our products and services meet the new demands of our customers.


Cooperation with our group of companies is therefore based on the systematic development of strategic suppliers who are involved in our demanding projects at an early stage.

The associated supplier development offers suppliers reliable growth prospects and a long-term, trusting and cooperative business relationship.


Our purchasing portfolio is diverse. We need supplies and services in many areas.
