Galvanized Steel Sheet Packaging:
Galvanized steel plates are available in two packaging types: cut-to-length sheets and coil-wrapped sheets. Typically, iron plate packaging is used, with moisture-proof paper lining and secured with iron hoops on a pallet. The wrapping must be secure to prevent friction between the galvanized steel plates inside.
Galvanized steel sheets are焊接 steel plates with a surface coating of hot-dip or electro-galvanized zinc, widely used in construction, home appliances, shipbuilding, container manufacturing, and the electromechanical industry. They are categorized into standard electrolytic plates and fingerprint-resistant electrolytic plates. The fingerprint-resistant plates add a fingerprint-resistant treatment to the standard electrolytic plates, making them sweat-resistant, commonly used on parts that do not require additional treatment, with the grade SECC-N. Standard electrolytic plates are further divided into phosphatized plates and passivated plates, with phosphatized being more commonly used, known as SECC-P or "p material." Passivated plates come in oiled and un-oiled varieties.
Galvanized steel sheets can be divided into the following categories 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. This process is primarily carried out using a continuous galvanizing technique, where rolled steel plates are continuously dipped into a zinc-coated molten bath to produce galvanized steel plates.
2. Alloyed Galvanized Steel Sheet: This type of steel sheet is also manufactured by the hot-dip process, but immediately after exiting the槽, it is heated to around 500°C to widely solicit, allowing the formation of an alloy coating of zinc and iron. This galvanized sheet exhibits good adhesion to paint and weldability.
3. Electro-Galvanized Steel Sheets: These sheets produced by electroplating offer good workability. However, the coating is thinner compared to hot-dip galvanized sheets, and its corrosion resistance is not as good.
4. Single-sided galvanized steel sheet and double-sided differential galvanized steel sheet: Single-sided galvanized steel sheet refers to products that are zinc-coated on only one side. It offers better adaptability in welding, painting, rust prevention, and processing compared to double-sided galvanized sheets. To overcome the drawback of the uncoated side, there is also a type of galvanized sheet with a thin zinc coating on the other side, known as double-sided differential galvanized steel sheet.
5. Alloy and Composite Galvanized Steel Sheets: These sheets are made by alloying zinc with other metals such as lead and zinc, even forming composite galvanized sheets. They offer both rust-proof properties and excellent painting performance. In addition to the aforementioned five types, there are also colored galvanized steel sheets, printed coated galvanized steel sheets, and polyvinyl chloride laminated galvanized steel sheets, etc.
Galvanized steel plate refers to steel plate with a zinc coating on its surface. Galvanizing is a commonly used, economical, and effective method of corrosion prevention, with about half of the world's zinc production used for this process.
