１．Product Overview

SS400 Electro Galvanized Steel Coil combines structural-grade steel performance with zinc coating protection for applications requiring durability, formability, and corrosion resistance. The electro-galvanized surface provides a clean appearance, while phosphate treatment enhances coating adhesion and processing reliability.

The product is widely used in transportation equipment, construction components, industrial fabrication, machinery manufacturing, and general engineering projects.

２．Technical Solution

The steel substrate is coated through an electro-galvanizing process to provide uniform zinc coverage and stable corrosion protection. The phosphate-treated surface improves resistance to environmental exposure and creates an excellent base for painting and further finishing operations.

The combination of strength, weldability, and surface quality makes this material suitable for both structural and fabricated components.
