Hot Dipped Galvanized Steel Sheet in Coil (GI coil) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristic. Usually hot dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.

Product Advantages
01.Anticorrosive:13 years in heavy industrial areas,50 years in the ocean,104 years in the suburbs and 30 years in cities.
02.Cheap:The cost of hot-dip galvanizing is lower than that of other coatings.
03.Reliable:The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
04.Strong toughness:The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use. 05.Comprehensive protection:Every part of the plated piece can be galvanized,and is fully protected even in depressions,sharp corners,and hidden places.
06.Save time and energy:Galvanizing process is faster than other coating methods.

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.
