Zn coated GI sheets

Galvanized sheet means is coated with a layer of metallic zinc on the surface of the steel sheet.,this kind of galvanized steel sheet is called galvanized sheet.Galvanized steel sheets are often used to prevent corrosion on the surface of the steel sheet and prolong its life. It is mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce industries.

Galvanized sheet

Galvanized sheet means is coated with a layer of metallic zinc on the surface of the steel sheet.,this kind of galvanized steel sheet is called galvanized sheet.Galvanized steel sheets are often used to prevent corrosion on the surface of the steel sheet and prolong its life. Mainly divided into the following two categories: 1,hot dip galvanized steel sheet.

The steel sheet is immersed in a molten zinc bath to adhere a zinc-plated steel sheet to the surface. At present, it is mainly produced by a continuous galvanizing process, that is, a coiled steel plate is continuously immersed in a plating tank in which zinc is melted to form a galvanized steel sheet; 2,alloyed galvanized steel sheet.

This steel sheet is also produced by hot dip, but immediately after it is discharged, it is heated to about 500 °C to form an alloy film of zinc and iron. This galvanized sheet has good adhesion and weldability of the coating. It is mostly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce industries.

Zinc plating is an economical and effective rust prevention method .There are various patterns on the surface of galvanized sheet, which can be divided into zero spangle, small spangle and large spangle. Generally, it is single-sided galvanized, and some customers also require double-sided galvanized.

Product advantages：

Superior quality. Every part of the plated parts can be plated with zinc, even in recesses, sharp corners and hidden places can be fully protected.
Economical and practical. The cost of anti-rust of galvanized sheet is lower than that of other paint coatings.
Strong corrosion resistance. In the suburban environment, the standard galvanized anti-corrosion layer can be maintained for more than 50 years. In offshore areas, the standard galvanized anti-corrosion layer can be maintained for 20 years.
Can be further processed. The metallurgical bond between the galvanized layer and the steel becomes a part of the surface.
Strong resilience. The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
