1. Product Overview

Hot dipped galvanized steel coils are produced through a continuous hot-dip galvanizing process, forming a stable zinc coating layer on the steel surface. This coating improves corrosion resistance and helps extend service life in industrial processing and structural applications.

The thickness range of 0.09–3.8 mm covers both thin-gauge processing and medium structural use. With widths of 1000–1250 mm, the coils are suitable for standard slitting, roll forming, and cut-to-length equipment used in manufacturing lines.

2. Technical Solution

Product performance is based on the following technical characteristics:

• Hot dip galvanizing with controlled coating weight (Z60–Z275)
• Zinc coating providing barrier protection and sacrificial protection
• Balanced strength and ductility for forming and structural use
• Uniform coating thickness for stable downstream processing

Yield strength of 195–420 MPa supports structural performance, while tensile strength of 270–500 MPa improves resistance to deformation during fabrication and service.
