Q195 Z120 Electro Galvanized Steel Sheet 1.0mm Phosphate Treated EGI Sheet for Construction Applications

１．Product Overview

Q195 Z120 Electro Galvanized Steel Sheet is designed for construction components, industrial fabrication, appliance manufacturing, and general engineering applications. Manufactured with a uniform electro-galvanized zinc coating and phosphate-treated surface, the product combines corrosion resistance, good formability, and surface cleanliness for downstream processing.

The smooth finish and stable coating quality make it suitable for fabrication operations requiring painting, bending, stamping, and assembly.

２．Technical Solution

The steel sheet is produced through an electro-galvanizing process that deposits a controlled zinc layer onto the steel substrate. This process provides excellent coating uniformity and a smoother surface compared with conventional galvanized products.

The phosphate treatment enhances paint adhesion and surface protection while supporting secondary processing such as powder coating, welding, stamping, and roll forming.
