0.13-3mm Thickness Galvanized Steel Coil
Product Description
Galvanized coil, a thin steel plate is immersed in a molten zinc bath so that a layer of zinc adheres to the surface. At present, the continuous galvanizing process is mainly used for production, that is, the rolled steel plate is continuously immersed in a plating bath containing molten zinc to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also made by the hot dip method, but it is heated to about 500°C immediately after coming out of the tank to form an alloy film of zinc and iron. This kind of galvanized coil has good paint adhesion and weldability.






Materials
Steel material: Galvanized steel coils usually use low carbon steel or medium carbon steel as the base material. Common materials include Q195, Q235, etc.
Galvanized layer: The thickness of the galvanized layer is usually between 20g/m² and 275g/m², which can be customized according to customer needs.
Specifications
Thickness: The thickness of galvanized steel coil is usually between 0.3mm and 3.0mm, and the specific thickness can be customized according to requirements.
Width: Common widths range from 600mm to 1500mm, which can be provided according to customer needs.
Length: Galvanized steel coils are usually supplied in coil form and the length can be customized according to customer needs.
Production process
Hot-dip galvanizing process: Galvanized steel coils are usually coated using a hot-dip galvanizing process, where the steel coils are immersed in molten zinc to form a uniform zinc coating.
Electro-galvanizing: In some cases, electro-galvanizing can also be used for applications with lower requirements for zinc coating thickness.
Surface treatment
Surface Finish: The surface of galvanized steel coil is usually smooth and has a good appearance.
Anti-rust treatment: The galvanized layer provides good anti-rust protection and extends the service life of the steel.
Advantages
Corrosion resistance: The galvanized layer effectively prevents oxidation and corrosion of the steel, making it suitable for use in harsh environments.
Economical: The relatively low cost of galvanized steel coil makes it an affordable choice.
Good Processability: Galvanized steel coils are easy to cut, weld and form, suitable for various manufacturing processes.
Application Areas
Construction Industry: used for roofs, walls, pipes and structural supports.
Automotive Industry: Used in automotive body and chassis components.
Home appliance industry: used for home appliance housing and internal structure.
Manufacturing Industry: Used in machinery and other industrial applications.
Maintenance
Regular Inspection: It is recommended to regularly inspect the surface of the galvanized steel coil to ensure it is free of rust and damage.
CLEAN: Keep the surface clean to avoid accumulation of dirt and chemicals.
