Corrosion protection

The efficient AUMA corrosion protection is decisive for a high life endurance level of the devices. The AUMA corrosion protection system is based on a chemical preliminary treatment, followed by a two-layer powder coating of the individual components. In compliance with the corrosivity categories according to ISO 12944-2, various AUMA corrosion protection levels are provided to suit the different applications.
