By means of our strong supply network, we procure the materials we use from global and reliable distributors and approved subcontractors. We carry out incoming quality controls according to quality requirements and store the materials in appropriate conditions and carry out location-based tracking, sorting management of materials belonging to the customer or project, and in-house life cycle tracking of finished and semi-finished products. For the products we design ourselves, we manage alternative material management on a variant basis starting from the design. We recommend alternative materials when necessary during the production phase of customer orders.
