FAQ
1.What is the difference between galvanized steel strip and cold rolled steel strip?
The main difference lies in surface treatment and performance:
- Cold rolled steel strip has no protective coating and is prone to rust
- Galvanized steel strip has a zinc coating (Z30–Z275), which significantly improves corrosion resistance
- GI strip has a longer service life, especially in humid or coastal environments
2. What does “spangle” mean in galvanized steel?
“Spangle” refers to the visible crystalline pattern formed on the surface during the zinc solidification process.
Types include:
- Regular spangle (large visible pattern, like in the product image)
- Minimized spangle
- Zero spangle (smooth surface for painting or coating)
3. What zinc coating should I choose (Z30–Z275)?
The choice depends on your application:
- Z30–Z80 → Indoor use, light industrial applications
- Z100–Z180 → General construction and manufacturing
- Z200–Z275 → Outdoor, roofing, coastal or high corrosion environments
Higher zinc coating = better corrosion resistance + longer lifespan.
4. Can galvanized steel strip be customized?
Yes, we provide full customization services:
- Thickness and width (slitting service available)
- Zinc coating weight
- Surface type (spangle / zero spangle)
- Coil weight and inner diameter
- Special packaging requirements
5. What are the common applications of GI steel strip?
Galvanized steel strip is widely used in:
- Roofing sheets and wall panels
- Steel pipes and tubes manufacturing
- Cable armoring and protection
- Construction structures
- Automotive components
- Household appliances
