Galvanized steel coil
Galvanized steel coil is a steel plate or steel coil product that has been treated by hot-dip galvanizing process. The process involves dipping steel coils or sheets into molten zinc, creating a strong zinc coating that protects the steel from corrosion.
Galvanized steel coils have good corrosion resistance and weather resistance and are commonly used in construction, manufacturing, automotive, pipelines and other fields.
Galvanized coating
(1)Normal spangle coating
During the normal solidification process of the zinc layer, the zinc grains grow freely to form a coating with obvious zinc flower morphology.
(2)Minimized spangle coating
During the solidification process of the zinc layer, the zinc grains are artificially restricted to form the tiniest possible zinc flower coating.
(3)Spangle-free coating
By adjusting the chemical composition of the plating solution, a coating with a uniform surface without visible spangles is obtained.
(4) zinc-iron alloy coating
The steel strip after passing through the galvanizing bath is heat treated so that the entire coating forms an alloy layer of zinc and iron. The appearance of this coating is dark gray and has no metallic luster.Performance advantages of galvanized steel coils
1. Excellent anti-corrosion performance: There is a strong zinc coating on the surface of the galvanized steel coil, which effectively blocks the erosion of the steel by air, water and other corrosive factors, providing excellent corrosion resistance.
2. Good weather resistance: Galvanized steel coils are resistant to UV rays, oxygen and other weather factors, so they perform well in outdoor applications.
3. Excellent processability: Galvanized steel coils have good plasticity and can be processed by bending, forming, cutting, welding, etc., and are suitable for various shapes and sizes.
4. Reliable coating consistency: The galvanizing process can provide a uniform and consistent coating. Whether on flat steel plates or coils, the coating quality is relatively reliable, helping to improve product quality and appearance.
