SGCC Hot Dipped Galvanized Steel Strip 0.12mm × 100mm with Passivated Surface for Channel and Pipe Manufacturing

１．Product Overview

SGCC hot dipped galvanized steel strip is manufactured through a continuous hot dip galvanizing process to provide corrosion resistance and stable processing performance. The product is supplied in a 0.12mm thickness and 100mm width configuration, making it suitable for channel production, pipe manufacturing, light structural components, appliance parts, and general fabrication applications.

The galvanized coating helps protect the steel substrate from atmospheric corrosion while maintaining good formability for roll forming, stamping, bending, and welding operations.

２．Technical Solution

The steel strip is produced using cold rolled steel as the substrate followed by hot dip galvanizing. A zinc coating is metallurgically bonded to the steel surface, providing sacrificial corrosion protection.

Passivated surface treatment improves storage stability and reduces the possibility of white rust formation during transportation and storage. Various surface conditions including chromate treatment, oiling, phosphating, and lacquer sealing can be supplied according to processing requirements.
