0.09–3.8mm HDG Steel Coil with 40–450g/m² Zinc Coating and 1000–1250mm Width for Structural and Fabrication Use

0.09–3.8mm HDG Steel Coil with 40–450g/m² Zinc Coating and 1000–1250mm Width for Structural and Fabrication Use

1. Product Overview

Hot dip galvanized steel coils are produced by coating cold rolled steel with molten zinc through a continuous galvanizing process.

The resulting zinc layer provides corrosion resistance and allows the coil to be processed into sheets, strips, and formed components for structural and industrial use.

2. Technical Solution

Performance is defined by:

• Zinc coating weight (40–450 g/m²) → corrosion protection level
• Steel grade → mechanical strength and forming behavior
• Elongation (12–25%) → bending and stamping capability
• Surface treatment → storage stability and coating compatibility

3. Specifications

4. Application

• Construction roofing and wall panels
• Steel structure and light framing
• Automotive body and reinforcement parts
• Appliance panels and enclosures
• General fabrication and industrial equipment

5. Processing

• Cut-to-length sheet production
• Slitting into strip
• Roll forming
• Stamping and bending

6. Advantages

• Wide thickness range from thin gauge to structural use
• Flexible coating options for different environments
• Stable elongation suitable for forming processes
• Standard coil supply improves downstream efficiency

7. How to Choose

• Indoor use → Z60–Z120
• Outdoor construction → Z120–Z275
• Heavy corrosion environment → ≥Z275
• Deep forming → higher elongation grade
• Painting → chromated or anti-fingerprint

8. FAQ

Q1: What thickness range is available for galvanized steel coils?
Our coils are available from 0.09mm to 3.8mm, covering thin gauge processing to structural applications.

Q2: How to select the right zinc coating level?
Z60–Z120 is suitable for indoor use, while Z120–Z275 is recommended for outdoor or structural applications.

Q3: Can galvanized coils be processed into sheets or profiles?
Yes. Coils are typically converted into sheets, strips, or formed components through slitting and cut-to-length processing.

Q4: What surface treatment should be selected?
Oiled for storage protection, chromated for corrosion resistance, and anti-fingerprint for painting or appearance requirements.
