What is galvanized steel sheet?

To understand galvanized steel plate, First need to understand galvanized steel process. In this process, the steel is immersed in hot molten zinc, so that as it cools, it forms a layer of zinc on top. The zinc layer acts as a barrier between the steel and the environmental conditions that prevent its oxidation. Now, when galvanized steel is processed into steel, the final product is called galvanized steel. Galvanized steel is also produced by dipping ordinary steel directly into hot molten zinc.

What is the production process of galvanized steel plate?

1. Hot melted zinc before being applied, or steel plates that are being painted, sprayed or plated, are first cleaned in a degreasing solution. It is then dipped and placed in a container of hot dilute sulfuric acid. The steel is then cleaned with an aqueous solution of zinc, ammonium and chloride. All these steps ensure that the steel will not be contaminated in the long run and that the zinc coating will stick to it correctly. Even after the galvanizing process, check the final product thoroughly for gaps or discrepancies.

2. The rust-resistant and corrosion-resistant properties of galvanized steel make it an ideal steel plate for use in areas where oxidation or rust is highly likely. It is also a fairly affordable type of steel plate, mainly because of its low manufacturing cost compared to other steel plates, but also because it can be used straight away, i.e. without any further preparation or handling. Like other galvanized steel products, galvanized steel can be used for many years, which makes it a very beneficial steel plate.

What are the advantages and disadvantages of galvanized steel sheet?

1. Coated with a protective layer of zinc, galvanized steel is stronger, more durable, and more effective against corrosion and oxidation than ordinary steel. Depending on the use, coating thickness and overall quality, galvanized steel can serve the user for many years. The extra zinc layer also protects the steel from contamination, which is the second main way alloys rust.

2. Although immersion of steel in hot-melt zinc is more advantageous, galvanized sheet, zinc spraying, painting, or plating can result in more unfavorable galvanized steel. Galvanized steel produced in this manner is prone to chipping, cracking or other forms of degradation.

3. Depending on where GI steel sheet is used, it can be scratched, and the zinc layer itself often comes off, which can leave specific areas exposed and susceptible to rust. Whether you use steel designed to prevent rust by any other means, or wish to use galvanized steel, you need to keep the advantages and disadvantages of these materials in mind before choosing them.

With so many types and grades of steel, many people can be confused or misled.If you are looking for a supplier of high quality GI steel sheet at a reasonable price , the Shandong Hongqi Material Co., Ltd. is a very good choice.
