Astm A653 S350 Z275 G90 Galvanized Steel Strips Coils and Skin Pass Sheet Price

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Corrosion Resistance: Hot-dip galvanization (G90 coating) provides superior protection against rust and environmental exposure, extending product lifespan in harsh conditions.
  • Structural Integrity: Cold-rolled and skin-pass processed steel ensures high tensile strength, surface smoothness, and dimensional precision (tolerance ±3%), ideal for demanding applications.
  • Versatile Fabrication: Pre-treated surface allows seamless integration with cutting, punching, bending, and coating processes for diverse manufacturing needs.

Key features

  • 1. Material Technology: Hot-Dip Galvanized Coating & Cold-Rolled Finish

  • With a hot-dip galvanized coating (G90) and cold-rolled finish, you can achieve superior corrosion resistance and a smooth, durable surface. This combination outperforms uncoated steel in harsh environments by up to 200%, ensuring longevity in industrial or outdoor applications.*

  • 2. Performance Parameters: High-Strength ASTM A653 S350 Grade

  • With a yield strength of S350 (per ASTM A653), you can ensure structural integrity in heavy-duty applications, offering ~25% higher load-bearing capacity than standard steel grades.* The Z275 zinc coating thickness further enhances durability in corrosive conditions.

  • 3. Scenario Solutions: Roll-Form Flexibility & Precision Tolerance

  • With a roll-form design and ±3% tolerance, you can streamline storage, transportation, and fabrication for projects like automotive parts or construction frameworks. The rolled format reduces handling risks while maintaining precision.

  • 4. Certification Standards: Global Compliance (ASTM, DIN, JIS, etc.)

  • With compliance to ASTM A653 and international standards like DIN, BS, and JIS, you can meet strict industry regulations for quality and safety across global markets, ensuring seamless integration into certified supply chains.

  • 5. Customization & Processing: Versatile Fabrication Options

  • With processing services like punching, cutting, and bending, you can adapt the material to custom designs, reducing post-production adjustments by up to 40%*. The skin-passed finish also improves formability for complex shapes.
