HDG generally refers to hot-dip galvanizing. Hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the iron and steel parts first, in order to remove the iron oxide on the surface of the iron and steel parts, after pickling, it is cleaned in a tank of ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the hot dip coating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

The corrosion resistance is mainly determined by the thickness of the galvanized layer, so the thickness measurement is often the main basis for judging the quality of the galvanized layer. The angle and speed of the solution also have a great influence. Therefore, it is practically impossible to obtain a completely uniform coating thickness. Therefore, the measurement of the adhesion amount can never be judged by a single point (location). It is only meaningful to measure the average adhesion weight (g) per unit area (㎡). There are many methods to measure the adhesion amount, such as destructive section metallographic observation method, pickling method, non-destructive film thickness meter method, electrochemical method, estimation method of weight difference between incoming and outgoing goods, etc. The commonly used methods are the film thickness gauge method and the pickling method.
