Description
Introduction:
Galvanized steel coil, thin steel sheets that are dipped into a molten zinc bath so that a layer of zinc adheres to their surface. Currently it is mainly produced by the continuous galvanizing process, whereby rolls of steel sheet are continuously dipped into a bath of molten zinc to make a galvanized steel sheet; alloyed galvanized steel sheet. This steel is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to around 500°C to produce an alloy of zinc and iron.
Galvanizing Process:
1.Surface Preparation:
The steel coil is cleaned to remove any contaminants, rust, or mill scale from the surface, ensuring good adhesion of the zinc coating.
2.Galvanizing Bath:
The cleaned steel coil is then immersed in a bath of molten zinc at temperatures typically ranging from 430°C to 460°C (800°F to 860°F). The steel is coated with a layer of zinc through a metallurgical reaction known as galvanization.
3.Formation of Zinc Coating:
When the steel coil is immersed in the molten zinc, a series of alloy layers are formed on the surface of the steel, creating a protective zinc coating. This coating provides corrosion resistance and enhances the durability of the steel.
4.Thickness and Size:
Galvanized steel coil is available in various thicknesses and widths to suit different applications and manufacturing requirements. The thickness of the zinc coating, often referred to as the coating weight, can be specified according to industry standards or customer preferences.
Properties:
1.Corrosion Resistance:
The zinc coating acts as a barrier between the steel substrate and the surrounding environment, protecting the steel from corrosion, rust, and oxidation.
2.Durability:
The zinc coating provides added durability and longevity to the steel, making it suitable for outdoor and high-moisture environments.
3.Paintability:
Galvanized steel coil can be easily painted or coated with additional protective coatings to enhance its appearance and further improve its corrosion resistance.
4.Formability:
Galvanized steel coil retains its formability and ductility even after the galvanizing process, allowing it to be easily formed, shaped, and fabricated into various products and components.
5.Applications:
Galvanized steel coil is used in a wide range of applications across industries, including construction, automotive, agricultural, HVAC, appliances, and manufacturing. It is commonly used to fabricate roofing, siding, gutters, fences, HVAC ductwork, automotive parts, electrical enclosures, and structural components.
In summary, galvanized steel coil is a versatile and durable steel product that has been coated with a protective layer of zinc through a hot-dip galvanizing process. Its corrosion resistance, durability, paintability, formability, and wide range of applications make it a popular choice in various industries.

Advantages
Anticorrosive
13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.
Cheap
The cost of hot-dip galvanizing is lower than that of other coatings also with high quality.
Reliable
The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.
Strong Toughness
The galvanized layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.
Comprehensive Protection
Every part of the plated piece can be galvanized, and is fully protected even in depressions, sharp corners, and hidden places.
Save Time and Energy
Galvanizing process is faster than other coating methods.
Gi coil with good paint adhesion and weldability
