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 is the difference between Hot Dip Galvanized and Electro-Galvanized steel plates?
Hot dip galvanized steel is dipped into a molten zinc bath, creating a thicker coating with superior corrosion resistance. Electro-galvanized steel has a thinner, more precise coating applied via electroplating, which offers excellent processability but lower corrosion resistance.
In what applications are these galvanized steel sheets commonly used?
They are widely used in home appliances such as refrigerators, washing machines, air conditioning units, microwave ovens, lighting fixtures, televisions, and audio/video equipment due to their durability and rust resistance.
What surface treatments are available for your galvanized steel?
We offer multiple surface treatments including Chromated/Non-Chromated, Oiled/Non-oiled, and Skin pass finishes, with spangle options ranging from regular, minimum, zero, to big spangles.
How are the steel products packaged for international delivery?
Products are packed in secure bundles, wrapped in plastic bags and thin films, placed on wooden pallets, conforming to standard seaworthy export packaging. Custom packaging requests can also be accommodated.
Why is the chemical composition (like Carbon, Chromium, etc.) tested?
Testing chemical composition ensures the material meets strict performance metrics. For example, Carbon improves tensile strength and hardness, Chromium provides corrosion resistance, and elements like Manganese and Molybdenum optimize toughness and wear resistance.
