Q345 Electro Galvanized Steel Sheet 1.0mm x 1250mm EGI Coil for Structural Fabrication and Industrial Equipment

１．Product Overview

Electro Galvanized Steel Sheet (EGI) is manufactured by depositing a uniform zinc layer onto cold rolled steel through an electrolytic galvanizing process. The product combines a smooth surface finish, precise dimensional control, and reliable corrosion resistance, making it suitable for industrial equipment, structural fabrication, appliance manufacturing, and electrical enclosures.

This EGI steel sheet is designed for applications that require excellent surface quality, paintability, and forming performance while maintaining consistent mechanical properties throughout production.

２．Technical Solution

The steel substrate is processed through a continuous electro-galvanizing line where zinc is evenly applied to both sides of the sheet. Compared with conventional galvanized products, electro galvanized steel offers superior surface uniformity and coating consistency.

A phosphate treatment is applied after galvanizing to improve corrosion resistance and enhance paint adhesion. This surface condition supports subsequent operations such as powder coating, painting, stamping, and fabrication.
