Frequently Asked Questions (FAQ)
-
Q: What is the difference between SGCC and DX51D galvanized steel coil?
A: SGCC is a Japanese standard grade (JIS G3302) typically produced by hot-dip galvanizing, while DX51D is a European standard (EN 10346) for general forming. SGCC offers a wider coating weight range and is often preferred for construction applications in Asian markets. -
Q: Can you supply coils with coating weight higher than Z27?
A: Yes, we can produce up to Z35 (350 g/m²) upon request, but the standard range Z18–Z27 covers most common requirements. Please contact our sales team for special coating weights. -
Q: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 25 metric tons per specification. However, we accept trial orders (5–10 tons) for first-time cooperation to build trust. -
Q: How do you ensure the coating weight is uniform?
A: We use advanced air knife technology during galvanizing and perform triple-layer coating weight testing (TRI method) on each coil. A test certificate is provided with every shipment. -
Q: What packaging options do you offer for export?
A: Standard export packaging includes anti-rust paper, plastic film, steel strapping, and wooden edge protectors. Coils can be wrapped in PVC film or waterproof paper based on destination climate. -
Q: Do you provide third-party inspection services?
A: Yes, we welcome third-party inspections such as SGS, BV, or Intertek at the buyer's expense. Our factory is open for audit at any time. -
Q: How long is the delivery time?
A: For standard specifications, delivery is 15–20 days after receipt of deposit. Custom orders may require 25–30 days. We ship from Qingdao port, China. -
Q: What payment terms do you accept?
A: Typically T/T (30% deposit, 70% balance before shipment) or L/C at sight. Other terms can be negotiated for long-term contracts.
