Zinc Roll Forming Material Guide: Coil Sizes, Properties & Roofing Applications
Zinc Roll Forming Material
1. Overview of Zinc in Roll Forming
Zinc is a premium non-ferrous metal widely used in roll forming for architectural roofing, cladding, and façade systems. It is known for its natural corrosion resistance and ability to develop a protective patina over time.
In roll forming, zinc is commonly used for standing seam roofing, wall panels, and rainwater systems, particularly in European construction markets.
Compared to copper, zinc offers a more uniform appearance and lower cost while still providing long-term durability.
2. Material Composition & Structure
Zinc used in roll forming is typically:
- High-purity zinc (~99.5% or higher)
- Often alloyed with small amounts of copper and titanium
Structure
- Non-ferrous metal
- Soft and highly formable
- Self-protecting patina layer
