Key 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 components can be coated with zinc, even in recesses, sharp corners and hidden places for comprehensive protection
Simple inspection: The hot-dip galvanized layer can be tested visually and with simple non-destructive coating thickness measurement
Applications
Galvanized steel coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and other industries. Applications include 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.
Packaging & Shipping
Product packaging can be customized according to customer requirements and factory standards
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.
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
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 (Minimal 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
