1000–1250mm Width Hot Dipped Galvanized Steel Coil Z60–Z275 with 195–420 MPa Yield Strength for Structural and Manufacturing Use

1. Product Overview

Hot dipped galvanized steel coils are produced by immersing cleaned steel substrate into molten zinc, forming a metallurgically bonded coating. This process provides stable corrosion resistance and consistent surface quality, suitable for structural parts and downstream sheet fabrication.

The width range of 1000–1250 mm aligns with mainstream slitting and forming equipment, improving processing efficiency for manufacturing and construction applications.

2. Technical Solution

Product performance is determined by:

• Hot dip galvanizing with controlled coating weight (Z60–Z275)
• Zinc acting as barrier and sacrificial protection
• Balanced mechanical properties for forming and structural use
• Uniform coating thickness for stable processing

Yield strength 195–420 MPa supports load-bearing applications, while tensile strength 270–500 MPa ensures resistance to deformation during fabrication and service.
