Galvanzied Steel Coil Introduction :

Galvanized steel is also called hot-dip zinc or hot-dipped galvanizing. It is an effective way of metal anti-corrosion,  mainly used in the industries of metal structure facilities. De-rusted steel is dipped in to 500 °C zinc liquid and coated with zinc which provides corrosion protection.

Production process: pickling-washing-adding zinc liquid-stoving-galvanized-cooling-passivation-flattening-finishing. Galvanizing has a history of 140 years since it is used in industry by Frenchman in 1836. The large-scale development of galvanizing is in the last 30 years with the development of cold-strip steel.

 Main features:

Galvanized steel based on cold rolled steel strip has excellent machining performance and high stamping. It is beautiful with smooth surface, accurate size,flat panel and well-distributed spangle and stored for a long time after passivation and oiling. It is the good base metal for PPGI after surface treatment.

 Equipment Advantages:

 1,High quality products: products comply with the standard of GB3097-84 and  GB13987-87.

 2,High automation: It is controlled by PC system and equipped with frequency conversion.

 3,High production efficiency:Double-ended style and annual output 3.04 million tons.

 4,Low production cost: Advanced technology of removing iron keep the content of 2 valent iron under 0.6g/L and reduce zinc consumption 5-10kg/ton. The gas is the fuel.

 5,Long service life of zinc port: The heating is from Reflective wall and well-distributed. It can reduce corrosive rate.
