Product Specification

High Strength Hot Dipped Galvanized Steel Coil Z60–Z275 for Industrial Processing and Fabrication

1. Product Overview

Hot dipped galvanized steel coil is used in industrial applications where corrosion resistance, mechanical stability, and continuous processing efficiency are required. The hot-dip zinc coating forms a protective layer on the steel surface, helping reduce rust risk during storage, transportation, fabrication, and service.

For industrial users, material selection usually depends on coating level, strength range, coil dimensions, and surface condition. With 1000–1250 mm width and standard coil IDs of 508 mm and 610 mm, this product is suitable for mainstream decoiling, slitting, and forming lines.

2. Technical Solution

Product performance is based on the following technical characteristics:

• Continuous hot-dip galvanizing with controlled coating weight
• Zinc coating providing barrier protection and sacrificial protection
• Yield strength of 195–420 MPa for structural stability
• Tensile strength of 270–500 MPa for resistance to deformation
• Elongation of 12–25% for forming, bending, and profiling

This combination supports downstream processing such as cut-to-length, roll forming, stamping, and general fabrication, while maintaining stable surface protection.
