Product Description

0.15–3.8mm Z40–Z275 SGCC Big Spangle Hot Dipped Galvanized Steel Sheet JIS G3302 for Pipe Forming and Structural Applications

1. Product Overview

Big spangle galvanized steel sheet is produced by continuous hot-dip galvanizing, forming visible zinc crystal patterns on the surface.

It is typically used in structural and pipe-forming applications where appearance uniformity is not critical.

2. Technical Solution

Key performance factors include:

Zinc coating (40–275 g/m²)
Spangle structure affecting surface behavior
Base steel grade (SGCC / DX51D) ensuring formability

3. Specifications

Parameter	Value
Thickness	0.15–3.8 mm
Width	1000–1500 mm,
Length	1000–5800 mm
Zinc Coating	40–275 g/m²
Spangle	Big / Regular / Minimized / Zero
Surface Treatment	Chromated / Oiled / Anti-fingerprint

4. Application

Pipe forming (ERW pipes, structural tubes)
Structural components
Roofing and cladding
Industrial fabrication
Appliance internal parts

5. Processing

Cut-to-length
Roll forming
Welding and fabrication

6. Advantages

Wide coating range from Z40 to Z275
Suitable for pipe forming applications
Stable forming performance
Compatible with continuous processing

7. How to Choose

Pipe forming → Big or regular spangle
Appearance parts → Minimized or zero spangle
Outdoor use → Z180–Z275 recommended

8. FAQ

Q1: What is the difference between big spangle and zero spangle?
Big spangle has visible zinc crystals, while zero spangle provides a smoother surface.

Q2: Can GI sheet be used for pipe manufacturing?
Yes, SGCC and DX51D are commonly used for pipe forming.

Q3: What coating is suitable for outdoor use?
Z180–Z275 is recommended for better corrosion resistance.

Q4: Can the length be customized?
Yes, cut-to-length service is available.
