Galvanized Steel Coil
HIGH QUALITY PRODUCTS
Galvanized Steel Coil
Carbon steel flat bars are essential components in various industries due to their versatility, strength, and suitability for multiple applications.
- Composition: Carbon steel flat bars are made from a blend of iron and carbon, with carbon being the primary alloying element.
- Shape and Dimensions: Flat bars have a rectangular cross-section with precise width and thickness dimensions.
- Hot Rolled Flat Bars: Produced at high temperatures, resulting in a scaled surface, typically used for applications where precise dimensions are not critical.
- Cold Drawn/Finished Flat Bars: Processed at room temperature, providing a smoother surface finish and tighter tolerances, suitable for applications requiring precise dimensions and a refined surface.

Typical Chemistry:
The chemistry of Galvanized Steel Coil mainly involves the composition of the base steel and the zinc coating:
Base Steel:
- Carbon (C): 0.05% to 0.25%
- Manganese (Mn): 0.20% to 1.40%
- Phosphorus (P): ≤ 0.04%
- Sulfur (S): ≤ 0.05%
- Silicon (Si): ≤ 0.50%
Zinc Coating:
- Zinc (Zn): The primary element, typically accounting for 99% of the coating.
- Aluminum (Al): Often added in small amounts (0.1% to 0.3%) to improve the adhesion and uniformity of the zinc layer.
Physical Properties:
Galvanized Steel Coils exhibit several key physical properties that make them suitable for a wide range of applications:
- Tensile Strength: Generally ranges from 270 MPa to 550 MPa, depending on the grade and thickness.
- Yield Strength: Typically ranges from 140 MPa to 450 MPa.
- Elongation: Varies from 15% to 35%, indicating good formability and ductility.
- Density: Approximately 7.85 g/cm³ (base steel) plus the density of the zinc coating, which is about 7.14 g/cm³.
- Hardness: Depends on the carbon content and heat treatment, typically ranging from 50 HRB to 100 HRB.
Specifications:
Galvanized Steel Coils are manufactured according to various standards and specifications to ensure quality and compatibility:
- ASTM A653/A653M: Standard specification for steel sheet, zinc-coated (galvanized) or zinc-iron alloy-coated (galvannealed) by the hot-dip process.
- EN 10346: European standard for continuously hot-dip coated steel flat products.
- JIS G3302: Japanese industrial standard for hot-dip zinc-coated steel sheets and coils.
Features:
Key features of Galvanized Steel Coils include:
- Corrosion Resistance: The zinc coating provides a protective barrier against rust and corrosion, extending the lifespan of the steel.
- Durability: Enhanced durability due to the protective zinc layer, making it suitable for harsh environments.
- Formability: Good ductility and formability, allowing it to be easily shaped and fabricated into various products.
- Aesthetic Appeal: Offers a clean, bright appearance that is often preferred for visible applications.
- Cost-Effectiveness: Provides a cost-effective solution compared to other corrosion-resistant materials such as stainless steel.
