Description
Large Spangle Galvanized Steel Sheet Zinc 40~275g GI Plate for Roofing & Construction
Product Overview

Large Spangle Galvanized Steel Sheet is produced through a hot-dip galvanizing process, forming a distinctive and attractive zinc crystal pattern (big spangle) on the surface. It provides excellent corrosion resistance and is widely used in roofing, wall cladding, ducting, and general construction.

Compared with zero spangle sheets, large spangle GI sheets offer a more decorative appearance and are preferred in visible applications.

Product Features
  • Attractive large zinc spangle surface (decorative finish)
  • Excellent corrosion resistance
  • Strong adhesion of zinc coating
  • Easy to process (cutting, bending, stamping)
  • Cost-effective solution for construction
  • Suitable for outdoor applications

Frequently Asked Questions
What is large spangle galvanized steel sheet?

Large spangle refers to visible zinc crystal patterns formed during the hot-dip galvanizing process, giving the sheet a shiny and decorative appearance.

What is the difference between large spangle and zero spangle?
Type Appearance Application
Large Spangle Visible flower pattern Roofing / decoration
Zero Spangle Smooth surface Painting / automotive
Is large spangle suitable for painting?

Not recommended for high-end painting, as the uneven surface may affect coating adhesion. Zero spangle is better for painting.

What zinc coating should I choose?

Z30-Z80 → Indoor use

Z100-Z180 → General outdoor

Z275 → High corrosion environment (recommended)

How long is the service life?

Normal environment: 10-20 years

Coastal/harsh environment: depends on zinc coating thickness
