For galvanized coils, the sheet steel is immersed in a molten zinc bath to make a sheet of zinc coated on its surface. It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ºC to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.Product Parameters

FAQ
1.Q:How to choose hot-dip galvanized coil and electroplated galvanized coil?
A:Hot dip galvanized coils are suitable for highly corrosive environments and outdoor applications, while electroplated galvanized coils are suitable for applications that require high surface smoothness but low corrosiveness, such as household appliances and automotive components.
2.Q:What is the corrosion resistance of galvanized coils?
A:Galvanized coils have excellent corrosion resistance, and the zinc layer can effectively isolate the steel from contact with the external environment, extending the service life of the steel, especially in humid environments.
3.Q:What processing techniques are suitable for galvanized coils?
A:Galvanized coils are suitable for various processing techniques, such as cold bending, stamping, welding, and shearing, and are particularly suitable for forming and component manufacturing.
4.Q:How to carry out anti-corrosion treatment on galvanized coils?
A:Galvanized coils have already undergone galvanizing treatment during the production process. If further anti-corrosion is required, spraying, plastic spraying, or adding anti rust paint can be used to improve their corrosion resistance in special environments.
5.Q:What is the environmental performance of galvanized coils?
A:Galvanized coils have good environmental performance, and the zinc layer can extend the service life of steel and reduce the frequency of replacement. Meanwhile, discarded galvanized coils can also be recycled and reused to reduce resource waste.
6.Q:What is the fire resistance of galvanized coils?
A:Galvanized coils themselves do not have fire resistance, but the zinc layer can provide some protection in a short period of time. In situations where fire prevention is required, additional fire-resistant coating treatment is usually necessary.
