1. Product Overview

Hot dipped galvanized steel coil is produced by applying a zinc coating through a continuous hot-dip galvanizing process, forming a protective layer on the steel surface. This coating improves corrosion resistance and helps extend service life in construction, fabrication, and general industrial environments.

The width range of 1000–1250 mm matches mainstream processing equipment and is suitable for slitting, roll forming, and cut-to-length production. In addition to corrosion resistance, bright surface condition is often selected when cleaner appearance or smoother downstream handling is required.

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 surface condition for storage, processing, and appearance requirements

Yield strength of 195–420 MPa supports structural applications, while tensile strength of 270–500 MPa ensures resistance to deformation during fabrication and service. Elongation of 12–25% supports bending, stamping, and profiling operations.

8. FAQ

Q1: What is the difference between bright and oiled surface?
Bright surface is cleaner in appearance, while oiled surface is mainly used for temporary storage protection.

Q2: What coating level is suitable for outdoor use?
Higher coating levels such as Z200–Z275 are typically selected for improved corrosion resistance.

Q3: Can coils be processed into sheets?
Yes, coils are commonly slit or cut into sheets according to downstream processing requirements.

Q4: What coil ID is compatible with standard equipment?
508 mm and 610 mm are standard coil IDs widely used in industrial production lines.

Q5: Is this material suitable for forming operations?
Yes, elongation of 12–25% supports bending, stamping, and roll forming processes.
