Galvanized coil is a metal material in which a thin steel plate is immersed in molten zinc to form a zinc layer on the surface of the steel plate. It has good anti-corrosion performance and is widely used in fields such as construction, home appliances, and automobiles. For example, in the construction industry, galvanized coil can be used to make roofs and walls; in the field of home appliances, it can be used to manufacture the shells of refrigerators, washing machines, and so on.

The Z275 galvanized steel coil is kind of a double-sided galvanized carbon steel. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc.

G60 is the coating grade of steel coil after continuous hot dip plating process. G represents the "galvanized" or galvanized layer of the product. The number 60 refers to the weight of the zinc around the steel coil or the thickness of the entire double-sided coating.

The material of DX51D galvanized sheet is a non-ferrous alloy with zinc as the matrix and other elements. The main alloying elements are aluminum, copper, magnesium and so on. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and resistance to atmospheric corrosion.
