Q295 Z90 Electro Galvanized Steel Sheet 1.2mm Phosphate Treated EGI Sheet for Industrial and Construction Applications

１．Product Overview

Q295 Z90 Electro Galvanized Steel Sheet is manufactured for industrial equipment, construction components, appliance manufacturing, and fabricated metal products. Combining a Q295 structural-grade steel substrate with a Z90 electro-galvanized coating, the product provides balanced strength, corrosion resistance, and fabrication performance.

The phosphate-treated surface improves coating adhesion and surface cleanliness, making the material suitable for painting, powder coating, stamping, and assembly operations.

２．Technical Solution

The steel sheet is produced through an electro-galvanizing process that creates a uniform zinc layer across the steel surface. This process delivers excellent surface quality and coating consistency for applications where appearance and precision are important.

The phosphate treatment enhances corrosion resistance during storage and improves adhesion for subsequent coating processes. The combination of Q295 steel strength and Z90 coating performance makes the material suitable for structural and industrial applications.
