0.09–3.8mm Hot Dipped Galvanized Steel Coil Z60–Z275 with 1000–1250mm Width and 195–420 MPa Yield Strength for Structural Applications

0.09–3.8mm Hot Dipped Galvanized Steel Coil Z60–Z275 with 1000–1250mm Width and 195–420 MPa Yield Strength for Structural Applications

1. Product Overview

Hot dipped galvanized steel coils are produced through a continuous galvanizing process, forming a uniform zinc coating on the steel surface. This coating improves corrosion resistance and ensures consistent performance in both indoor and outdoor environments.

The combination of 1000–1250 mm width and stable mechanical properties supports efficient processing for construction, automotive, and manufacturing applications.

2. Technical Solution

Product performance is based on:

• Hot dip galvanizing with controlled zinc coating (Z60–Z275)
• Zinc acting as barrier protection and sacrificial layer
• Balanced strength and elongation for forming and structural use
• Uniform coating thickness for consistent processing

Yield strength of 195–420 MPa provides structural support, while elongation of 12–25% ensures forming capability without cracking.
