0.09–3.8mm 40–450g/m² Hot Dipped Galvanized Steel Coil SGCC DX51D+Z for Construction and Industrial Applications

0.09–3.8mm 40–450g/m² Hot Dipped Galvanized Steel Coil SGCC DX51D+Z for Construction and Industrial Applications

1. Product Overview

Hot dipped galvanized steel coil is produced by immersing cold rolled steel into molten zinc, forming a metallurgical bonding coating that improves corrosion resistance and service life.

The coating range of 40–450 g/m² allows the material to be used in environments from general indoor conditions to high-corrosion outdoor applications.

2. Technical Solution

Performance is based on:

• Zinc coating providing sacrificial corrosion protection
• Uniform coating distribution ensuring stable durability
• Cold rolled substrate delivering consistent mechanical properties

3. Specifications

4. Application

• Construction roofing and wall systems
• Structural components
• Automotive parts
• Household appliances
• Industrial fabrication

5. Processing

• Slitting
• Cut-to-length (sheet production)
• Roll forming
• Bending and stamping

6. Advantages

• Wide zinc coating range (40–450 g/m²) for different environments
• Stable processing performance from cold rolled base
• Adaptable surface treatment for downstream use
• Compatible with multiple international standards

7. How to Choose

• Indoor application → 40–120 g/m²
• Outdoor construction → 120–275 g/m²
• High corrosion environment → 275–450 g/m²
• Painting or forming → Anti-fingerprint surface
