Hot dipped galvanizing is a process of coating steel with a thin layer of zinc, which serves as a barrier between the steel and the elements. The steel is dipped into a molten bath of zinc, which creates a metallurgical reaction that forms an alloy coating. This coating, or barrier, provides superior corrosion protection from harsh environmental conditions.
Wayne can help you choose the ideal galvanized steel for your application based on the fabrication method and type of environment in which the steel will be used.
Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of the zinc layer and the cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and use purpose.
（1）Spangled galvanized steel sheet is the spangle obtained by the condensation of the zinc coating under normal conditions after galvanizing. It is mainly used in buildings and other places where there is little direct contact with the human body.
（2）Galvanized steel sheets without spangles are mainly produced through a special production process to control the lead in the zinc pot to a certain level, or after the strip steel is out of the galvanized pot, it undergoes special treatment to control the spangles to less than a certain level. Mainly used in home appliance housing.
