A thin alloy layer readily permits normal fabrication practices without incurring significant coating damage. Hot dip coatings are specified in a wide range of coating weight categories as shown in Table 1.Hot Dip Galvanizing StandardsIn general, the coating thickness on these products is considerably less than batch hot dip galvanized items of the same thickness. For example, a coating designation of Z350 means the total mass on both sides is 350 g/m 2 , or approximately 175 g/m 2 on a single area.
