The biggest advantage of galvanized steel plate is excellent corrosion resistance, painting, decoration and good formability. With the development of industry, hot dip galvanizing products have been used in many fields. The advantage of hot dip galvanizing is that the anti-corrosion life is long and it has been a popular anti-corrosion treatment method to adapt to the environment widely. It is widely used in power tower, communication tower, railway, highway protection, road light pole, Marine component, building steel structure component, auxiliary facilities of substation, light industry and so on.

G90 refers to the coating type and coating weight on the steel plate. "G" means that the coating is galvanized. Meanwhile, the number "90" represents the weight of zinc on the steel. G90 galvanized steel is hot-dip galvanized cold-rolled steel sheet to improve durability.

Galvanized sheet is 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 galvanized sheet material is a non-ferrous alloy formed by adding other elements to the zinc matrix. The main alloy 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 Z150 in the DX51D Z150 galvanized steel sheet 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.

Z120 is the coating name, which means that the coating thickness on both sides is approximately 120g/㎡ or 36g/㎡ (three-point test). Z120 grade galvanized steel is coated with zinc to make it more durable.

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
