Surface Coating

We offer surface treatments to improve the resistance to wear and corrosion as pretreatment for subsequent joining processes such as gluing and welding but also for improving the thermal and electrical conductivity values for the finished product. DGS has its own in-house passivation line covering various coating methods and maintains long-term partnerships with suppliers to meet individual customer requirements.
