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.
