Product Description
Hot Dipped Galvanized Steel Coil
Hot Dipped Galvanized Steel Sheet in Coil (GI) is manufactured by processing Full Hard sheet through acid washing and rolling procedures before immersion in a zinc pot, creating a protective zinc film on the surface. This process delivers exceptional corrosion resistance, superior paint adhesion, and excellent workability due to zinc's inherent properties. The manufacturing processes and specifications for hot-dipped galvanized steel sheets and coils are fundamentally identical.
Manufacturing Process
Hot-dip galvanizing involves applying a protective zinc coating to steel or iron sheets to prevent rust formation and extend material lifespan.
Key Advantages
- Outstanding corrosion protection through zinc's self-sacrificing characteristics
- Superior paint adhesion and surface compatibility
- Excellent formability and processability
- Customizable zinc coating thickness (maximum 120g/m²)
Performance Characteristics
- Corrosion Resistance: The zinc coating effectively isolates steel from oxygen and moisture, significantly reducing corrosion rates and extending service life
- Heat Resistance: Maintains structural integrity and performance in high-temperature environments without deformation, melting, or damage
- Weather Resistance: Preserves surface finish and mechanical properties across diverse climatic conditions, unaffected by environmental factors
