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
Q1: What are the main types of galvanized steel plates?
A1: The main types include hot-dip galvanized steel plate, alloyed galvanized steel plate, electric galvanized steel plate, single/double-sided difference galvanized steel plate, and alloy/composite galvanized steel plate.
Q2: How does single-sided galvanized steel compare to double-sided?
A2: Single-sided galvanized steel is coated on only one side, offering better adaptability for welding, coating, and rust treatment. To resolve the lack of zinc on one side, double-sided difference galvanized steel has a thin zinc layer on the reverse side.
Q3: What are the standard shipping container options and sizes?
A3: We offer shipping in 20ft GP (5898x2352x2393mm, 24-26CBM), 40ft GP (12032x2352x2393mm, 54CBM), and 40ft HC (12032x2352x2698mm, 68CBM) containers.
Q4: Why is Chromium (Cr) added to the steel composition?
A4: Chromium is added to enhance the steel's overall hardness, tensile strength, toughness, and to provide resistance against wear and corrosion.
Q5: What surface treatments are available for these steel coils?
A5: Available surface treatments include Chromated/Non-Chromated, Oiled/Non-oiled, and Skin pass, with spangle options ranging from regular, minimum, zero, to big spangles.
Q6: What is the packaging standard for export delivery?
A6: The steel coils are packed in bundles, plastic bags, thin film, and wooden pallets to meet standard seaworthy export packaging requirements, or customized based on client demands.
