A653 G3302 10346 galvanized coil

Here are some common galvanized sheet materials from abroad, along with their chemical compositions, properties, and uses:

1. American standard:

- ASTM A653:

- Chemical composition: Mainly contains elements such as iron (Fe), carbon (C), manganese (Mn), phosphorus (P), sulfur (S), etc. The content of each element fluctuates within a certain range to meet different performance requirements. For example, the carbon content is usually low to ensure the toughness and weldability of the steel plate, and manganese helps improve the strength of the steel plate.

- Properties: It has good corrosion resistance. This is because the zinc layer on the surface can effectively prevent the steel plate from rusting in the atmospheric environment. At the same time, this material has high strength and can meet the strength requirements of materials in the fields of construction and mechanical manufacturing. Its processing performance is also good, and it can be processed by cutting, stamping, bending, etc.

- Uses: Widely used in the construction industry, such as building structural parts, roof panels, wall panels, etc.; in the automotive manufacturing field, it can be used to manufacture body parts, chassis parts, etc.; it is also used to manufacture various metal products, such as shelves, storage boxes, etc.

2. Japanese standard:

- JIS G3302:

- Chemical composition: It contains appropriate amounts of carbon, silicon (Si), manganese, phosphorus, sulfur and other elements, and the content of these elements is strictly controlled. For example, silicon can improve the strength and hardness of the steel plate, but too high a content will affect the welding performance of the steel plate.

- Properties: The galvanized layer is uniform and has strong adhesion, which can provide good anti-corrosion protection for the steel plate. Its mechanical properties are stable, with good tensile strength, yield strength and elongation, and is suitable for various processing and forming operations.

- Uses: Widely used in the construction, home appliance, and automotive industries in Japan. In construction, it is used to build industrial plants and civilian residences; in the home appliance field, it is used to manufacture the shells of refrigerators, washing machines, etc.; in the automotive industry, it is used to manufacture interior parts and body panels of cars.

3. European standard:

- EN 10346:

- Chemical composition: According to different grades and models, their chemical compositions will be different, but generally they contain basic elements such as iron, carbon, manganese, phosphorus, sulfur, etc., and there are clear regulations on the content of each element. For example, for some high-strength models, a small amount of alloy elements such as molybdenum (Mo) and niobium (Nb) may be added to improve the strength and toughness of the steel plate.

- Properties: It has high strength and good forming performance, which can meet the processing requirements of complex shapes. At the same time, its corrosion resistance is also excellent and is suitable for various harsh environmental conditions.

- Uses: Widely used in the fields of construction, bridges, and mechanical manufacturing in Europe. In the construction field, it can be used to build steel structures, roofs and walls of large buildings; in bridge construction, it is used to manufacture structural parts such as bridge girders and columns; in mechanical manufacturing, it is used to manufacture parts of various mechanical equipment.

What are the coatings of galvanized sheet?

Galvanized sheet coatings mainly include the following:

1. Zinc coating (Zinc coating): The most common coating, providing good corrosion resistance.

2. Zinc-aluminum alloy coating (Zinc-aluminum alloy coating): Offers enhanced corrosion resistance compared to pure zinc coating.

3. Zinc-magnesium-aluminum alloy coating (Zinc-magnesium-aluminum alloy coating): Combines the advantages of zinc, magnesium and aluminum, providing excellent corrosion resistance and durability.

What are the thicknesses of the galvanized layer of galvanized sheet?

The thicknesses of the galvanized layer on galvanized sheet can vary. Generally, common thicknesses include:

- 80 grams per square meter (equivalent to a certain thickness).

- 120 grams per square meter.

- 180 grams per square meter.

- 275 grams per square meter. And so on. Different thicknesses are used for different applications to meet different corrosion resistance requirements.
