Application:

Construction industry:

Metal sheets used to make roofs and walls, with good weather resistance and appearance decoration. For example, the roofs and walls of industrial plants and warehouses are often made of plates made of galvanized steel coils. Production of steel beams, steel columns and other components in building structures to enhance the stability and durability of the building.

Automobile manufacturing industry:

Manufacture of car body shells and parts to provide a certain strength and rust resistance. For example, galvanized steel coils may be used in parts such as doors, hoods, etc.

Home appliance industry:

Production of shells for appliances such as refrigerators, washing machines, air conditioners, etc., to protect internal parts and give a beautiful appearance.

Electronic Equipment:

As the shell material of some electronic equipment, such as distribution boxes, switchgear cabinets, etc.

Furniture Manufacturing:

Used to make frames and structural components of metal furniture.

Pipe Manufacturing :

Can be processed into various pipes for ventilation, drainage and other systems.

Agricultural Field:

Construction of agricultural facilities, such as frames and covering materials for greenhouses.

Transportation:

Used in the manufacture of railroad carriages, shells and internal structures of ships. In conclusion, galvanized steel coils play an important role in multiple industries due to their excellent properties and characteristics.

 Physical properties:

Appearance:

The surface has a uniform galvanized layer, showing a silver-white or blue-gray color with a metallic luster.

Hardness: It has a certain degree of hardness and can withstand a certain degree of external force without deformation.

Expansion: It has good ductility and can be processed into different shapes by rolling, stamping, and other processes.

Density: High density, which makes it more stable in use.

Conductivity: It has a certain degree of conductivity, but it is less conductive than pure metals such as copper.

Chemical properties:

Corrosion resistance:

The galvanized layer effectively protects the inside of the steel coil, making it have good corrosion resistance in humid, acid and alkali environments. For example, in the atmospheric environment of coastal areas, galvanized steel coils can remain rust-free for a long time. –

Antioxidant properties:

The zinc layer on the surface prevents the coil from coming into direct contact with oxygen, slowing down the oxidation process.

Stability:

Under normal temperature and pressure, the chemical properties are relatively stable, making it difficult to react violently with common chemical substances.

Paintability:

After proper treatment, it can be coated to increase the protective performance and aesthetics of its surface. These physical and chemical properties make galvanized steel coils widely used in many fields.
