Product Specification

SGCC SGCD JIS G3302 Hot Dipped Galvanized Steel Strip Zinc Coated Steel Coils

1．Product Overview

SGCC SGCD JIS G3302 hot dipped galvanized steel strip is used for welded pipes, construction profiles, roofing accessories, home appliance shells, automotive corrosion-resistant parts, and general metal fabrication.

The product is manufactured through continuous hot dip galvanizing. The zinc coating protects the steel substrate from corrosion, while passivated, chromated, and oiled surface treatments help improve storage stability and export transportation protection.

2．Technical Solution

The galvanized steel strip uses SGCC, SGCD, DX51D+Z, Q195, Q235, and Q345 grades for different forming and structural requirements.

The available zinc coating range is 40–450g/m², supporting different service environments. Spangle options include regular, minimized, big, and zero spangle.

Surface treatment options include passivated, chromated, oiled, and anti-fingerprint. These treatments are selected according to storage time, humidity conditions, and downstream processing requirements.
