G60 Galvanized Sheet Description
G60 is the coating grade of steel sheet after continuous hot dip plating process. G represents the "galvanized" or galvanized layer of the product. The number 60 refers to the thickness of the zinc around the steel sheet or the thickness of the entire double-sided coating. To get the amount of galvanizing on one side, you need to divide this number by two.
Galvanized steel sheet G60 is coated with molten zinc. After the continuous coating process at a speed of 600 feet per minute, the excess zinc on the steel plate is removed by high-pressure air. This is in order to produce the desired coating thickness. After cooling, the sheet is rolled into a roll, ready for manufacturing.
Scope of Application
Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.
