Purchased and delivered materials to Nijmegen are always inspected, checked, and weighed on our calibrated weighing bridges on-site. A standard procedure upon the arrival of the materials includes measuring for any potential radioactivity. Any anomalies are photographed and weighed if necessary to avoid misunderstandings. Once everything is confirmed to be in order, the agreed purchase amount is reimbursed. The materials we provide are always carefully sorted and checked. De Leeuw Metalen offers its clients complete assurance.
