Spray galvanizing means that the molten zinc is sprayed at high speed against the surface to be coated. Surface blasted to Sa 2 ½ before galvanizing. Pickling is needed, however not be made for this method.

The technology is primarily used for corrosion protection of large and complex engineering products. It also works as a complement to the hot dip galvanizing for repairs. An important advantage of this method is that the zinc coating thickness can be varied and also creates the surface a very good base for painting.

To coat iron and steel parts with zinc is a very common and relatively inexpensive method to protect parts against corrosion. There are three methods for galvanized parts, hot, electroplating and spray galvanizing. All methods give the surface a cathodic protection, zinc acts as a sacrificial anode. This means that when a crack where the iron / steel is exposed, protected parts of the surrounding zinc. Therefore, zinc is often used as a basis for painting.
