Electro Galvanized Steel Coil
Galvanized sheet coils, treated with special processes, have excellent performance characteristics.Its material is mainly low-carbon steel, ensuring excellent cold bending and welding performance, while its stamping performance is fully demonstrated, thus meeting various complex processing requirements.Galvanized sheet coils play an indispensable role in various fields such as construction, home appliances, and automobile manufacturing.
Electro Galvanized Steel Coil
Galvanized coil, also known as galvanized coil, is a thin steel plate that has undergone special treatment.
The manufacturing process involves immersing the steel plate into a molten zinc bath to form a layer of zinc coating on the surface.
This material has a wide range of applications in various fields such as construction, home appliances, automobile manufacturing, container manufacturing, transportation facilities, and agricultural equipment.
Its material is mainly made of low-carbon steel and requires excellent cold bending and welding performance, as well as certain stamping performance to meet various complex processing requirements.
Comparison between Electroplated Galvanizing and Hot Dip Galvanizing
| Aspect | Hot-Dip Galvanizing (HDG) | Electro-Galvanizing (EG) |
|---|---|---|
| Process | Immersion in molten zinc (≈450°C) | Electroplating in zinc electrolyte (room temperature) |
| Coating Thickness | Thicker (50-150 μm), uneven | Thinner (5-30 μm), uniform |
| Adhesion | Strong metallurgical bond (Zn-Fe alloy layers) | Mechanical bond (electrodeposited zinc) |
| Appearance | Dull gray, spangled pattern | Smooth, shiny, matte finish |
| Corrosion Resistance | Superior (thicker coating, sacrificial protection) | Moderate (thinner coating) |
| Durability | Long-lasting (decades in harsh environments) | Shorter lifespan (indoor/mild conditions) |
| Cost | Lower for large items (bulk processing) | Higher (precise, energy-intensive) |
| Applications | Structural steel, fencing, pipelines, outdoor uses | Automotive parts, electronics, appliances |
| Post-Treatment | May require trimming (drips) | Ready-to-use (no drips) |
| Environmental Impact | Higher energy (zinc melting) but minimal waste | Chemical waste (electrolyte disposal) |
Products advantages
application area
Galvanized coils are widely used in multiple fields due to their excellent corrosion resistance:
(1) Construction industry: Galvanized coils are commonly used as steel in building structures, which can effectively extend the service life of buildings. Common applications include roofs, walls, doors and windows, etc.
(2) Automobile manufacturing: In automobile production, galvanized coils are used for the external structure of the vehicle body, which can effectively prevent rusting and improve the durability and safety of the car.
(3) Home appliance manufacturing: Many home appliances use galvanized coils for their shells and internal structures to enhance their corrosion resistance and extend their service life.
(4) Mechanical manufacturing: Galvanized coils have also been widely used in the production of mechanical equipment, especially for some mechanical equipment that needs to be used outdoors. The galvanized layer can effectively prevent rusting.
