0.15–3.8mm G40–G90 Hot Dipped Galvanized Steel Sheet SGCC DX51D with AFP / Oiled / Chromated Surface for Container Applications

0.15–3.8mm G40–G90 Hot Dipped Galvanized Steel Sheet SGCC DX51D with AFP / Oiled / Chromated Surface for Container Applications

1. Product Overview

Hot dipped galvanized steel sheet is produced by applying a zinc coating onto cold rolled steel through a continuous hot dip process.

G40–G90 coating range provides balanced corrosion protection and cost efficiency, making it suitable for container plate and general industrial applications.

2. Technical Solution

Performance is based on:

• Zinc coating G40–G90 providing sacrificial corrosion protection

• Uniform coating thickness ensuring stable durability

• Surface treatments improving storage and processing performance

• Compatibility with forming, welding, and coating processes

3. Specifications

4. Application

• Container plate and transport equipment

• Construction structures and roofing components

• Household appliance panels

• Automotive components

• Industrial equipment enclosures
