Zinc Coated Hot Dipped Galvanized Steel Coil 914–1250mm with 40–275g/m² Coating

1. Product Overview

Zinc coated hot dipped galvanized steel coil is used in sheet processing applications where corrosion resistance, forming stability, and continuous production efficiency are required. The zinc layer formed during hot dip galvanizing helps protect the steel surface during storage, transport, fabrication, and end use.

This specification focuses on 0.30–1.50 mm thickness and 914–1250 mm width, which are commonly used for appliance panels, roofing sheets, industrial housings, and general fabricated components. The width range is suitable for standard slitting, cut-to-length, and roll forming lines.

2. Technical Solution

Product performance is based on the following technical characteristics:

• Continuous hot dip galvanizing with controlled zinc coating mass
• Zinc coating providing barrier protection and sacrificial protection
• Cold rolled base metal supporting flatness and downstream fabrication
• Multiple spangle options for visible finish and later processing
• Standard coil dimensions for mainstream industrial line compatibility

For appliance and industrial sheet applications, coating mass affects corrosion resistance, while tensile strength and elongation affect bending, stamping, and forming behavior. This is why zinc coating, spangle type, and downstream processing route are usually considered together.

• Multiple spangle options help match appearance and finishing requirements
• Cold rolled base improves sheet consistency for downstream forming
• Coil format supports efficient continuous processing and material utilization

7. How to Choose

• Appliance panel use → smaller or zero spangle is often preferred for cleaner appearance
• Roofing and visible galvanized sheet → regular spangle is commonly selected
• Higher humidity or outdoor exposure → choose higher coating such as 180–275 g/m²
• Stamping and bending applications → prioritize balanced elongation and tensile strength
• Continuous production lines → confirm 914–1250 mm width and 508 / 610 mm coil ID with equipment capacity

8. FAQ

Q1: Is this product galvanized steel coil or prepainted steel coil?
This specification is hot dipped galvanized steel coil, not prepainted steel coil.

Q2: Can the coil be processed into sheets or strips?
Yes, it can be cut to length into sheets or slit into narrower strips according to downstream requirements.

Q3: Which spangle type is suitable for appliance panels?
Small spangle or zero spangle is commonly preferred when a cleaner surface appearance is required.

Q4: Is 914–1250 mm width suitable for roofing and panel lines?
Yes, this width range is commonly used in roll forming and sheet fabrication lines.

Q5: What zinc coating level is commonly used for general industrial applications?
The suitable coating depends on service environment, but 40–275 g/m² covers common indoor, semi-exposed, and construction-related requirements.
