Galvanized steel plates are coated with a layer of zinc to prevent corrosion on the surface of the steel plate, thereby extending its service life. This zinc-coated steel plate is referred to as galvanized plate.
Galvanized steel sheets can be categorized into the following types based on production and processing methods:
1. Hot-Dip Galvanizing: Immerse thin steel plates into a molten zinc bath to coat them with a thin layer of zinc. Currently, the process predominantly uses a continuous galvanizing technique, where rolled steel plates are continuously dipped into a zinc-coating bath to produce galvanized steel sheets.
2. Alloy-Deposited Galvanized Steel Sheet: This steel sheet is also manufactured using the hot-dip process, but after being dipped, it is immediately heated to around 500°C to widely solicit, allowing the formation of an alloy coating of zinc and iron. This zinc-coated sheet features good adhesion to paint and welding properties.
3. Electrolytic Galvanized Steel Sheet: This type of galvanized steel sheet, produced by electrolysis, offers good workability. However, the coating is thinner and less corrosion-resistant than hot-dipped galvanized steel sheet.
4. Single-sided and double-sided electro-galvanized steel sheets: Single-sided electro-galvanized steel sheets are products that are zinc-coated on only one side. They offer better adaptability in welding, painting, rust prevention, and processing compared to double-sided electro-galvanized sheets. To overcome the drawback of the uncoated side, there is also a type of electro-galvanized sheet with a thin zinc coating on the other side, known as double-sided differential electro-galvanized steel sheets.
5. Alloyed and Composite Galvanized Steel Sheets: These sheets are made by alloying zinc with other metals such as lead and tin, and can also be composite galvanized. They offer both excellent rust-proof properties and good painting performance. In addition to the aforementioned five types, we also offer color galvanized steel sheets, printed coating galvanized steel sheets, and polyvinyl chloride laminated galvanized steel sheets, etc.
Galvanized steel sheet materials are widely used in various industries, with most being employed in the automotive manufacturing sector, storage containers, public facilities, construction, and also in furniture. Galvanizing is a popular corrosion prevention method, not just because it forms a protective layer on the steel surface, but more importantly, even if there are damaged areas in this layer, it can maintain long-lasting corrosion resistance, thereby extending the service life.
Galvanized steel sheet packaging:
Galvanized steel sheets are available in two packaging types: cut-to-length sheets and coil-packed sheets. Generally, they are packaged with a moisture-proof paper lining and secured with iron bands wrapped around a wooden pallet. The binding must be sturdy to prevent the sheets from rubbing against each other inside.
