Product Packaging
Product packaging can be customized according to customers and according to factory standards
Advantages
- Low processing cost: The cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings
- Multi-faceted protection: Each part of the plated parts can be plated with zinc, even in recesses, sharp corners and hidden places can be protected in many ways
- The inspection is simple and convenient: The hot-dip galvanized layer can be tested visually and with a simple non-destructive coating thickness table
Applications
Galvanized steel coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and other industries. Such as building roofs, highway guardrails, sheet metal processing, roof grilles, household appliance enclosures, ventilation ducts, chimneys, kitchen utensils, grain storage and transportation, frozen processing of meat and aquatic products, etc.

Frequently Asked Questions
1. What does zinc coating weight mean? What options do you offer?
Zinc coating weight (also called zinc mass) is measured in g/m² (both sides total). It determines the corrosion resistance lifespan of the steel.
Note: Higher coating weight = longer service life = higher cost. We recommend selecting based on your actual environmental conditions.
| Grade | Coating Mass (g/m²) | Typical Application |
|---|---|---|
| Z40-Z80 | 40-80 | Indoor use, light protection |
| Z100-Z140 | 100-140 | General construction, roofing |
| Z180-Z275 | 180-275 | Heavy industry, structural components |
| Z350-Z450 | 350-450 | Coastal areas, high-corrosion environments |
2. What standards do you follow?
Our galvanized steel coils comply with major international standards:
- ASTM A653 - American Standard
- JIS G3302 - Japanese Standard
- EN 10346 - European Standard
- GB/T 2518 - Chinese Standard
3. What is spangle? Regular spangle vs zero spangle - which should I choose?
Spangle refers to the visible crystal patterns on the surface of galvanized steel, formed during the solidification of the zinc coating.
Recommendation: If you plan to paint directly on the surface, zero spangle is strongly recommended for better paint adhesion.
| Type | Description | Best For |
|---|---|---|
| Regular Spangle | Visible snowflake-like crystals | Applications where appearance is not critical; prepainted base |
| Zero Spangle (Minimal Spangle) | Smooth, uniform surface with no visible crystals | Painting applications, prepainted steel, automotive parts, where surface smoothness matters |
4. Does galvanized steel rust?
While galvanized steel offers excellent corrosion protection, white rust (zinc oxide) can occur under certain conditions:
- Poor ventilation during storage
- High humidity or condensation
- Direct contact with rainwater
5. How to prevent white rust?
Prevention methods:
- Passivation treatment - We apply chromate or chromium-free passivation before shipment
- Oil coating - Anti-rust oil can be applied for ocean freight shipments
- Proper storage - Store in a dry, ventilated warehouse; avoid outdoor storage
