Frequently Asked Questions (FAQ)
1. What is the minimum order quantity (MOQ) for this galvanized steel coil?
The MOQ is typically 1 coil (approx. 3-8 tons). For smaller quantities, please contact our sales team to discuss availability.
2. Can I get samples before placing a bulk order?
Yes, we offer free samples (courier cost charged by the buyer). Samples are available in A4 size or small coil pieces for testing.
3. What is the difference between Q235B and Q235A?
Q235B has stricter chemical composition and mechanical property requirements compared to Q235A, ensuring better weldability and impact toughness. Our coil uses Q235B for superior performance.
4. How long does the galvanized coating last?
The lifespan depends on the environment. In normal atmospheric conditions, a coating weight of 100 g/m² can last 15-20 years before needing maintenance. Heavier coatings are available for more corrosive environments.
5. Do you provide third-party inspection certificates?
Yes, we can arrange inspection by SGS, BV, or other independent agencies at the buyer's request. The cost is shared or borne by the buyer based on negotiation.
6. What packaging do you use for export?
We use standard seaworthy packaging: inner plastic film, waterproof paper, metal strapping, and edge protectors. The coil is wrapped with corrugated paper or steel sheet for extra protection. Custom packaging is available.
7. Can you cut the coil into sheets or slits?
Yes, we offer slitting and cut-to-length services. Please provide your desired dimensions in the inquiry, and we will provide a quotation.
8. What is the payment term?
Common payment terms include T/T (30% deposit, 70% against copy of B/L) or L/C at sight. Other terms are negotiable based on order value and client relationship.
