Galvanized steel is widely used in construction, piping, and industrial projects across the globe. To stay competitive in international markets, exporters must focus on product durability, compliance, and cost-efficiency. Here are five proven ways to improve galvanized steel for export success.
✅ 1. Use Consistent Zinc Coating Thickness
A zinc coating thickness of 85μm or more is recommended for markets with high corrosion resistance requirements (like the Middle East or coastal regions). Following ISO 1461 or ASTM A123 ensures that your products pass salt spray tests and meet buyer expectations.
✅ 2. Choose the Right Galvanizing Method
Hot-dip galvanizing is preferred for export-grade durability. It forms a strong bond between zinc and steel, offering better protection than cold or electro-galvanizing. For structural and outdoor applications, hot-dip is often mandatory.
✅ 3. Optimize Steel Surface Preparation
Poor surface cleaning leads to coating defects. Use acid pickling, shot blasting, or alkaline degreasing before galvanizing. A clean surface ensures better adhesion and a smoother finish—important for both appearance and long-term protection.
✅ 4. Match Product to Export Standards
Different markets require different standards. For example:
ASTM A53 for North America
BS EN 10240 or ISO 1461 for Europe and the Middle East
Certify your products accordingly to reduce customs issues and gain trust from international buyers.
✅ 5. Improve Packaging and Marking
High-quality packaging reduces damage during sea freight. Use moisture-resistant wrapping and proper bundle marking with clear size, zinc thickness, and heat numbers. This improves professionalism and reduces rejection rates on arrival.
Conclusion
By improving zinc coating quality, galvanizing methods, surface preparation, and packaging, exporters can enhance product value and reliability. Meeting international standards ensures your galvanized steel is export-ready and trusted by global customers.
