SGC340 SGC400 EGI Steel Sheet 0.8mm Thickness 1250mm Width with 80g/m² Zinc

１．Product Overview

SGC340 and SGC400 Electro Galvanized Steel Sheets are designed for applications requiring a clean surface appearance, dimensional accuracy, and reliable corrosion protection. Manufactured with electro-galvanizing technology, the product provides a uniform zinc layer and stable mechanical performance suitable for fabrication and industrial processing.

The phosphate-treated surface improves coating adhesion and supports secondary finishing processes such as painting, forming, and stamping. These steel sheets are widely used in appliance manufacturing, construction components, automotive parts, and industrial equipment.

２．Technical Solution

The steel substrate is electro galvanized to achieve a controlled zinc coating and smooth surface finish. The phosphate treatment further enhances surface protection and paint compatibility. The combination of structural steel grades and zinc protection delivers a balance of corrosion resistance, formability, and durability.

The product can be processed through bending, punching, welding, roll forming, and coating operations while maintaining surface consistency and dimensional stability.

３．Specifications

４．Application
