Steel

Steel sheets can effectively be protected against corrosion by extremely thin (only a fraction of a millimeter = approx. 1 to 20 micrometers ) layers of zinc. Using galvanized sheet metal is interesting because of its low price. Even if the protective zinc layer is being damaged there still won’t be any corrosion, since the „cathodic protection“ is maintained up to a distance of approx. 2 millimeters. Application areas are automotive industry, ventilation and air conditioning technology as well as the construction industry etc.
