Hot-dip galvanizing is one of the effective means to delay the environmental corrosion of iron and steel materials, it is the surface of the cleaned, activated iron and steel products immersed in molten zinc, through the reaction and diffusion between iron and zinc, in the iron and steel products surface plating good adhesion of zinc alloy coating.

Galvanized coil is made of a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. So it is also known as cold galvanized steel

DX51D material is a mild steel galvanized layer for steel products. Specifically, DX51D is a steel grade characterized by its cold-formed bending and profiling qualities.

The Z150 in the DX51D Z150 galvanized coil is the actual coating name. The manufacturer describes the DX51D Z150 material as a mild steel galvanized layer for steel products. Specifically, DX51D is a steel grade characterized by its cold-formed bending and profiling qualities.

The material of DX52D galvanized coil is a non-ferrous alloy composed of zinc as the matrix. 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.

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.
