With the continuous expansion of the use of galvanized sheet, in the modern strip continuous galvanizing unit, through the strip finishing can achieve the following purposes:
(1) Improve the flatness and flatness of the thin plate, but also the surface of the zinc particle pressing, so that the surface of the strip is smooth, which is particularly beneficial for the future deep drawing and other occasions with high precision;
② The polishing roller used has been shot peening in advance, so the surface of the plating plate after polishing has a certain roughness. It can improve the adhesion of the coating, but also can store a certain amount of grease, in deep punching processing, is beneficial to the lubrication of the die;
(3) For the later coating process of the plate, although the surface control into small zinc flowers but small zinc flowers can still be exposed through the paint layer. Therefore, for some high requirements of galvanized sheet, the surface of the small zinc flower needs to be processed by finishing. This can make galvanized sheet to obtain a more uniform appearance of silver white;
(4) By finishing, the yield point can be lowered to make the yield platform disappear or not obvious, which can prevent the slip line in the future drawing or deep drawing and improve the possibility of deep drawing.
Galvanized sheet is mainly used in construction, household appliances, automobiles, machinery, electronics, light industry and other industries

Galvanized sheet is a steel plate with a layer of zinc on its surface. Galvanizing is an economical and effective anticorrosion method that is often used. About half of the world's zinc production is used in this process.
Galvanized steel plate is to prevent the surface of the steel plate from being corroded to prolong its service life, coated with a layer of metal zinc on the surface of the steel plate, this coated steel plate is called galvanized plate.
