Product Description
Product Parameter
- (1) Hot dip galvanized steel plate: Dip the sheet steel into a molten zinc bath and make it adhere to a sheet of zinc. At present, the main use of continuous galvanized process production, that is, the roll of steel plate continuous immersion in the melting of zinc plating tank made of galvanized steel plate.
- ② Alloyed galvanized steel plate: This kind of steel plate is also made by hot dip, but immediately after the trough, it is heated to about 500℃, so that it produces zinc and iron alloy film. The galvanized sheet has good coating density and weldability.
- ③ Electric galvanized steel plate: The galvanized steel plate produced by electroplating method has good processability. But the coating is thin, corrosion resistance is not as good as hot dip galvanized sheet.
- ④ Single-sided plating and double-sided galvanized steel plate: Single-sided galvanized steel, i.e. galvanized on only one side of the product. In welding, coating, anti-rust treatment, processing and other aspects, with better adaptability than double-sided galvanized sheet. In order to overcome the shortcomings of not coated zinc on one side, there is a galvanized sheet coated with thin layer of zinc on the other side, that is, double-sided difference galvanized sheet.
- ⑤ Alloy, composite galvanized steel plate: It is made of zinc and other metals such as aluminum, lead, zinc alloy and composite plating into the steel plate. This kind of steel plate has not only excellent rust resistance, but also good coating performance.
In addition to the above five, there are color galvanized steel plate, printing coated galvanized steel plate, polyvinyl chloride laminated galvanized steel plate, etc. But at present the most commonly used is still hot dip galvanized sheet.

Frequently Asked Questions
What are the main differences between hot dip and electric galvanized steel plates?
Hot dip galvanized steel plate is produced by immersing the steel plate in a molten zinc bath, providing a thicker zinc coating and superior corrosion resistance. Electric galvanized steel plate is made via electroplating, resulting in a thinner coating that offers excellent processability but lower corrosion resistance.
Why would I choose a single-sided galvanized steel plate?
Single-sided galvanized steel plates are coated only on one side. This design provides better adaptability for specific manufacturing processes such as welding, coating, anti-rust treatments, and other processing steps compared to double-sided galvanized sheets.
What are the common applications for this galvanized steel?
This material is widely used in home appliances and consumer electronics, including refrigerators, washing machines, air conditioning units, microwave ovens, lighting fixtures, televisions, and audio/video equipment.
What packaging options are available for shipping?
Products are shipped in bundles, plastic bags, thin films, or on wooden pallets. We use standard seaworthy export packing methods to ensure safe transit, and can also customize the packaging according to specific customer requirements.
How does the addition of Chromium (Cr) and Nickel (Ni) affect the steel?
Chromium enhances the hardness, tensile strength, toughness, and provides essential anti-wear and corrosion resistance. Nickel further enhances the overall strength, hardness, and corrosion resistance of the alloy.
