Because the tracker’s application circumstances are complicated, structural anticorrosion treatment is very important. Basic surface treatment is hot dipped galvanization, in which the thickness and evenness of galvanization is critical. The graph below illustrates the expected service of a galvanized coating as a function of coating thickness in varying atmospheric conditions. As you can see, the life of a coating is linearly related to its thickness. Very simply, the thicker the coating, the longer it will last. The minimum thickness of hot dipped galvanization for our tracker is 100μm. The thickness of hot dipped galvanization is put into IQC process.
