30-400mm Z10-Z27 Hot Dipped Galvanized Steel Strip with Regular Spangle for Pipe and Construction Applications

１．Product Overview

This hot dipped galvanized steel strip is manufactured from hot rolled carbon steel through a continuous galvanizing process. The zinc coating provides effective corrosion protection while maintaining good formability and processing performance. The product is widely used in pipe manufacturing, construction components, home appliances, automotive parts, and packaging industries.

With zinc coating options from Z10 to Z27 and regular spangle surface finish, the strip offers stable coating distribution and reliable protection in indoor and outdoor service environments.

２．Technical Solution

The steel strip is produced using continuous hot dip galvanizing technology. The steel substrate passes through a molten zinc bath where a metallurgically bonded zinc layer is formed on both sides of the strip.

The galvanized coating acts as a sacrificial protection layer, helping prevent base steel corrosion. Anti-finger treatment can be applied to improve handling performance and reduce surface staining during transportation and storage.

３．Specifications

４．Application

This galvanized steel strip is commonly used for greenhouse pipes, gas pipes, heating pipes, roof panels, roof grilles, appliance housings, kitchen equipment, automotive corrosion-resistant components, packaging materials, refrigeration equipment, and storage systems.

The product is suitable for applications requiring both corrosion resistance and economical processing performance.

５．Processing

The strip can be processed by slitting, roll forming, bending, stamping, punching, welding, profiling, and cutting operations.

Customized strip width, thickness, coating weight, and coil dimensions can be supplied according to project requirements.
