１．Product Overview

SGH540 Electro Galvanized Steel Coil is designed for applications requiring higher strength, reliable corrosion protection, and good fabrication performance. The electro-galvanized coating provides a clean and uniform surface, while phosphate treatment improves coating adhesion and surface durability.

The material is widely used in structural components, industrial equipment, appliance manufacturing, automotive parts, and corrosion-resistant fabricated products.

２．Technical Solution

The steel substrate is coated with zinc through an electro-galvanizing process, producing a consistent protective layer across the surface. Phosphate treatment further enhances corrosion resistance and creates an ideal surface for painting, powder coating, and secondary processing.

SGH540 offers higher strength characteristics than standard commercial grades, making it suitable for demanding forming and structural applications.
