Galvanized Iron (GI) is produced by continuously hot-dip coating a steel substrate with a layer of Zinc (Zn), providing excellent protection against environmental factors, particularly oxidation and corrosion. This type of steel is widely used across various industries.
2. Key Features and Advantages
Good Corrosion Resistance: The Zinc coating effectively shields the steel from environmental exposure, extending product lifespan. Bright and Smooth Surface: Ensures high aesthetic appeal, easy processing, and paint adhesion. Cost-Effective Solution: An economical choice for a wide range of construction projects.
3. Technical Specifications
The galvanized steel edges are leveled using Tension Leveler Technology, and the surface is further refined with Skinpass Technology for superior smoothness. Steel Grade: G350 - G550 Coating Weight: Z30 - Z275 (g/m²) Width: 762mm - 1250mm Thickness: 0.20mm - 0.80mm Base Steel Suppliers: Posco, Hoa Phat, Formosa
4. Production Process
