0.09–3.8mm Hot Dipped Galvanized Steel Coil Z60–Z275 with 3–8MT Coil Weight for Construction and Manufacturing Applications
0.09–3.8mm Hot Dipped Galvanized Steel Coil Z60–Z275 with 3–8MT Coil Weight for Construction and Manufacturing Applications
1. Product Overview
Hot dipped galvanized steel coils are produced by applying a zinc coating through a continuous hot-dip galvanizing process, forming a stable protective layer on the steel surface. This coating improves corrosion resistance and helps extend service life in construction, fabrication, and general manufacturing environments.
The thickness range of 0.09–3.8 mm covers both thin-gauge processing and medium structural applications. Coil weight of 3–8 MT is commonly used for standard handling, transportation, and downstream processing, making the product suitable for slitting, cut-to-length, roll forming, and sheet fabrication 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 mechanical properties for forming and structural use
- Controlled coil weight for compatibility with standard processing equipment
Yield strength of 195–420 MPa supports structural performance, while tensile strength of 270–500 MPa improves resistance to deformation during fabrication and service. Elongation of 12–25% also supports forming operations such as bending, stamping, and profiling.
