Key Advantages
  • Low processing cost: Hot-dip galvanizing rust prevention costs are lower than other paint coatings
  • Multi-faceted protection: All parts of plated components receive zinc coating, including recesses, sharp corners, and hidden areas
  • Simple inspection: Hot-dip galvanized layers can be tested visually and with simple non-destructive coating thickness gauges
Applications

Galvanized steel coil products are mainly used in construction, light industry, automotive, agriculture, animal husbandry, and fishing industries. Applications include building roofs, highway guardrails, sheet metal processing, roof grilles, household appliance enclosures, ventilation ducts, chimneys, kitchen utensils, grain storage and transportation, and frozen processing of meat and aquatic products.

Frequently Asked Questions
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.

Coating Mass (g/m²) Typical Application
40-80 Indoor use, light protection
100-140 General construction, roofing
180-275 Heavy industry, structural components
350-450 Coastal areas, high-corrosion environments

Note: Higher coating weight = longer service life = higher cost. We recommend selecting based on your actual environmental conditions.

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

All products come with Mill Test Certificates (MTC) that can be provided upon shipment.

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.

Type Description Best For
Regular Spangle Visible snowflake-like crystals Applications where appearance is not critical; prepainted base
Zero Spangle Smooth, uniform surface with no visible crystals Painting applications, prepainted steel, automotive parts where surface smoothness matters

Recommendation: If you plan to paint directly on the surface, zero spangle is strongly recommended for better paint adhesion.

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
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
