Galvanized Steel
Galvanized steel is produced from both cold-rolled and hot-rolled coils, featuring a protective zinc coating that shields the steel from atmospheric corrosion. The galvanizing process involves the reaction between molten zinc and the iron substrate, creating an alloy layer that bonds the base metal and the zinc coating.
Hot-Dip Galvanizing Process:
- Pretreatment: Iron and steel parts are first pickled to remove surface oxides.
- Cleaning: After pickling, the parts are cleaned in a solution of ammonium chloride, zinc chloride, or a mixture of both.
- Galvanizing: The cleaned parts are then immersed in a bath of molten zinc, where the zinc forms a uniform and strongly adherent coating.
Advantages of Hot-Dip Galvanizing:
- Uniform Coating: Ensures consistent protection across the entire surface.
- Strong Adhesion: The zinc coating bonds firmly to the steel, providing long-lasting durability.
- Long Service Life: The combination of uniformity and strong adhesion results in extended product life.
Galvanized steel coils are widely used in industries with stringent requirements for corrosion resistance, durability, strength, and appearance. They can be further processed to form various coatings or applications, making them versatile for a range of industrial and construction needs.

Galvalume Steel
Aluminum-Zinc Coated Steel Coil: An Essential Alloy Material
Aluminum-zinc coated steel coil is a versatile and widely used alloy material, composed of 55% aluminum, 43.4% zinc, and 1.6% silicon. This alloy is formed at a high temperature of 600°C, creating a dense quaternary crystal structure of aluminum-iron-silicon-zinc.
Key Characteristics:
Corrosion Resistance:
- Superior Corrosion Resistance: The aluminum-zinc coating provides excellent corrosion resistance, up to three times that of pure galvanized steel.
- Protective Layer: When the zinc layer wears down, the aluminum forms a protective oxide layer, preventing further corrosion of the underlying steel.
Heat Resistance:
- High-Temperature Tolerance: Aluminum-zinc coated steel can withstand temperatures above 300°C, making it suitable for applications such as chimney pipes, ovens, and lampshades.
- Oxidation Resistance: The high-temperature oxidation resistance is comparable to that of aluminum-coated steel, ensuring long-term durability in high-heat environments.
Thermal Reflectivity:
- High Reflectivity: The thermal reflectivity of aluminum-zinc coated steel is twice that of galvanized steel, making it an excellent choice for thermal insulation materials.
Economy:
- Cost-Effective: Due to the lower density of the 55% Al-Zn alloy, the area covered by aluminum-zinc steel coils is about 3% larger than that of pure zinc-coated steel under the same weight and thickness, providing better value for money.
