Galvanized Steel Coil
Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
Hot-dip galvanizing is the process of applying a protective zinc coating to a steel sheet or iron sheet, to prevent rusting.
* Excellent anti-corrosion, paintability, and processability due to the self-sacrificing characteristic of zinc.
* Available to select and produce the desired amount of zinc gilded and in particular enables thick zinc layers(maximum 120g/m2).
* Classified as either zero spangle or extra smooth depending on whether the sheet undergoes skin pass treatment.
| Property | Technical Parameters | Competitive Advantage |
| Corrosion Resistance | ≥1500h salt spray test (55% Al-Zn coating) | 3-6× longer lifespan vs. galvanized steel (GI) |
| Heat Resistance | Sustains 315°C long-term (400°C short-term peak) | Outperforms GI (fails at 200°C) |
| Solar Reflectivity | ≥75% sunlight reflectivity | 20% higher than pre-painted steel |
| Formability | Elongation ≥20% (ASTM A792) | Better stamping performance than stainless |
| Eco-Friendliness | Chromium-free passivation (RoHS compliant) | Meets EU ELV directives |
| Industry | Applications | Recommended Grade | Benefits |
| Building Envelope | Airport terminals Industrial cladding | AZ150 (150g/m² coating) | 25-year maintenance-free, 40% lifecycle cost reduction |
| Appliances | AC outdoor units, oven interiors | AZ100 (100g/m² coating) | 50% cost saving vs. stainless steel |
| Automotive | Exhaust heat shields, fuel tank brackets | AZ180 + passivation | 30% weight reduction, passes 2000h salt spray |
| Solar Mounting | Ground-mounted PV structures (desert environments) | AZ200 + S550GD | Sand erosion resistance, 30+ year lifespan |
| Agriculture | Livestock barn roofs, grain silos | AZ120 + PE film lamination | 3× longer maintenance cycles |
Key Features:
1.Corrosion Resistance: The zinc layer acts as a barrier against oxygen and moisture in the air, preventing rust. Coating thickness ≥20g/m² significantly enhances durability.
2.Superior Surface Quality :smooth and flawless surface, free from zinc spangles or burrs, enabling direct painting or printing for enhanced aesthetics.
3.Excellent Processability:suitable for cold bending, stamping, and welding. The coating adheres firmly to the base steel, resisting peeling during forming.
4.Eco-Friendly:Some processes adopt chromium-free passivation to reduce environmental impact.
