Frequently Asked Questions
1. What is the typical lifespan of your galvanized steel coils?
Depending on the zinc coating thickness and environmental conditions, galvanized steel can last between 20 to 50 years. High zinc coatings provide better corrosion resistance in coastal or industrial areas.
2. Can galvanized steel coils be painted?
Yes, they can. However, proper surface preparation or using a "skin pass" finish is recommended to ensure optimal paint adhesion.
3. What is the difference between regular and zero spangle?
Regular spangle has a visible crystalline flower pattern created during cooling. Zero spangle is cooled quickly to produce a smooth, uniform surface, often preferred for high-end painting applications.
4. Do you support third-party inspections?
Absolutely. We accept inspections from SGS, BV, CE, and other international agencies to guarantee the quality of the products before shipment.
5. How are the coils protected against moisture during sea freight?
We use a robust 3-layer packaging system: waterproof kraft paper, plastic film, and an outer steel sheet shell, all securely fastened to wooden pallets.
6. What range of zinc coating do you offer?
We provide a wide range of zinc coatings from 30g/m² up to 600g/m² to suit various industrial and construction requirements.
