0.09–3.8mm Z60–Z275 Hot Dipped Galvanized Steel Coil SGCC DX51D for Construction and Manufacturing Applications

0.09–3.8mm Z60–Z275 Hot Dipped Galvanized Steel Coil SGCC DX51D for Construction and Manufacturing Applications

1. Product Overview

Hot dipped galvanized steel coils are produced by immersing cold rolled steel into molten zinc, forming a metallurgical bonded coating layer.
The zinc coating provides stable corrosion protection, making the material suitable for long-term use in construction, manufacturing, and outdoor applications.

2. Technical Solution

Performance stability is based on:

• Hot dip galvanizing process (continuous galvanizing line)
• Uniform zinc coating distribution (Z60–Z275)
• Steel grade control (SGCC / DX51D series)
• Surface treatment selection for storage and processing conditions

3. Specifications

4. Application

• Roofing and wall cladding systems
• Steel structure and building frames
• HVAC ducts and ventilation systems
• Home appliance panels (washing machines, refrigerators)
• Automotive outer and inner components

5. Processing

• Slitting (coil → strip)
• Cut-to-length (coil → sheet)
• Roll forming
• Bending and stamping
• Pre-painting (PPGI base material)

6. Advantages

• Stable corrosion resistance based on zinc coating range
• Wide thickness coverage (0.09–3.8mm) for multi-industry use
• Compatible with standard coil ID (508 / 610 mm)
• Suitable for secondary processing (forming / painting)
• Consistent mechanical properties (YS 195–420 MPa)

7. How to Choose

• Outdoor construction → Z120–Z275
• General fabrication → Z60–Z120
• Painting purpose → Anti-fingerprint surface
• Roll forming → SGCC / DX51D base material
• Heavy-duty application → thickness ≥1.5mm

8. FAQ 

Q1: Can you supply coils in both 508mm and 610mm ID?
Yes, both coil IDs are available depending on your processing equipment.

Q2: What zinc coating is recommended for outdoor use?
Z120–Z275 is commonly selected for outdoor construction and roofing applications.

Q3: Can coils be processed into sheets or strips?
Yes, we support slitting and cut-to-length processing based on your size requirements.

Q4: What surface treatment should be used for painting?
Anti-fingerprint or chromated surface is recommended for better coating adhesion.

Q5: What is the typical coil weight for container shipment?
Usually 3–8 MT per coil, adjustable based on loading and customer requirements.
