DC03 Z80 Electro Galvanized Steel Sheet 0.95mm Phosphate Treated EGI Sheet for Industrial Buildings

１．Product Overview

DC03 Z80 Electro Galvanized Steel Sheet is manufactured for industrial buildings, appliance components, electrical cabinets, and precision metal fabrication. The DC03 substrate offers excellent cold-forming and drawing performance, while the Z80 electro-galvanized coating provides uniform corrosion protection and a smooth surface finish.

The phosphate-treated surface enhances paint adhesion and improves downstream processing performance, making the material suitable for fabrication operations requiring appearance consistency and dimensional precision.

２．Technical Solution

The steel sheet is produced using an electro-galvanizing process that applies a controlled zinc coating to the steel substrate. Compared with conventional galvanized products, electro galvanized steel provides a smoother and more uniform surface that is ideal for painting, powder coating, and visible applications.

The phosphate treatment improves coating adhesion and corrosion resistance during storage, transportation, and fabrication processes such as stamping, bending, and assembly.
