Hot DIP Galvanized Steel CoilMature production technologyAdvanced processing technologyComplete testing meansGalvanzied 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. Galvanzied Steel Coil
