Product Detail

Galvanized sheet refers to a steel sheet coated with a layer of zinc on the surface. Galvanizing is an economical and effective rust prevention method that is often used, and about half of the world's zinc production is used in this process.

According to the production and processing methods, it can be divided into the following categories:

Hot-dip galvanized steel sheet. Dip the thin steel plate into the molten zinc tank to make the thin steel plate with a layer of zinc adhered to its surface. At present, the continuous galvanizing process is mainly used for production, that is, the coiled steel plate is continuously immersed in a galvanizing tank with molten zinc to make a galvanized steel plate;

Alloy galvanized steel. This type of steel is also produced using the hot-dip galvanizing method, but is immediately heated to approximately 500°C after exiting the tank to form a zinc-iron alloy film. This type of galvanized steel exhibits excellent paint adhesion and weldability.

Electrogalvanized steel. Galvanized steel produced using the electroplating method offers excellent workability, but the coating is thinner and its corrosion resistance is inferior to that of hot-dip galvanized steel.

Main Application

Features

1. Corrosion resistance, paintability, formability, and spot weldability.

2. Widely used, primarily in small appliance components requiring high aesthetics. However, it is more expensive than SECC, leading many manufacturers to switch to SECC to save costs.

3. Classification by zinc layer: The size of the zinc spangles and the thickness of the zinc layer reflect the quality of the galvanizing process; the smaller the spangles and the thicker the zinc layer, the better. Manufacturers may also add anti-fingerprint treatment. Additionally, grades can be differentiated by the coating layer; for example, Z12 indicates a total coating of 120g/mm on both sides.

Application

Galvanized sheet and strip steel products are mainly used in industries such as construction, light industry, automobile, agriculture, animal husbandry, fishery, and commerce.

Roofing and Wall Materials: Galvanized sheet offers excellent weather resistance, resisting rain, snow, ultraviolet rays, and other natural factors. It is often processed into corrugated steel sheets and color-coated galvanized sheet (a color coating applied over the zinc coating).Steel Structural Components: In building steel structures, such as purlins, supports, and keels, galvanized sheet can be formed into various profiles through cold bending

Municipal Facilities: Used in the manufacture of municipal facilities such as streetlight poles, traffic signs, guardrails, and trash cans. These products are exposed to the elements for extended periods of time, and the galvanized coating effectively protects them from corrosion caused by rain, dust, and other factors, reducing maintenance costs.
