１．Product Overview

Z150 EGI Steel Coil is an electro galvanized steel product designed for applications requiring a smooth surface finish, corrosion resistance, and reliable forming performance. Produced with a uniform zinc coating and phosphate-treated surface, the material offers excellent appearance quality and enhanced paint adhesion.

The product is suitable for construction components, household appliances, automotive parts, industrial equipment, and storage systems where both durability and surface consistency are important.

２．Technical Solution

The steel substrate is processed through an electro-galvanizing line to apply a controlled zinc coating that provides corrosion protection and dimensional consistency. Phosphate treatment improves coating adhesion and surface stability during fabrication and painting processes.

The material supports various downstream manufacturing operations including stamping, bending, roll forming, welding, and coating applications.

３．Specifications

４．Application
