Galvanized Coil ASTM A653 CQ Z180 Regular Spangle DRY 1.9mm Thick and 1220mm Wide

DX51D+Z 1200*0.8mm High Quality Normall Spangle AFP Hot Dip Zinc Coated Steel Z150 for Roofing or Warehouse Doors   Brief Introduction ASTM A653 Galvanized Coil gets coated in layers of zinc because rust won't attack this protective metal. The most external layer is all zinc, but successive layers are a mixture of zinc and iron, with an interior of pure steel. These multiple layers are responsible for the amazing property of the metal to withstand corrosion-inducing circumstances. Zinc also protects the steel by acting as a "sacrificial layer." If rust does take hold on the surface of ASTM A653 Galvanized Coil, the zinc will get corroded first. This allows the zinc that is spread over the breach or scratch to prevent rust from reaching the steel. For countless outdoor, marine, or industrial applications, ASTM A653 Galvanized Coil is an essential fabrication component.   Production Flow Chart   The Protection Principle 1. Anodic reaction: Zn-2e=Zn2+ (The alloy coating loses electron, sacrificing itself in dissolution.) 2. Cathodic reaction: Fe2++2e=Fe (Fe gains electron reaction, being protected)   Specification 1. Thickness: 0.3-0.8mm 2. Width: 914-1250mm 3. Inner Diameter: 508mm 4. Weight of Steel Coil: 3-15MT 5. Coating Type: Pure Zinc 6. Available Dipped Layer: 50-150g/m2 7. Surface Finish Structure: Zero Spangle & Finishing Small Spangle 8. Available Surface Treatment: Passivating & Oiling & AFP & Filming   Mechanical Properties
