Frequently Asked Questions (FAQ)
-
Q: What is the difference between hot-dipped galvanized and pre-galvanized steel pipe?
A: Hot-dipped galvanized pipe is dipped in molten zinc after fabrication, creating a thicker, more durable coating that bonds with the steel. Pre-galvanized pipe is coated before forming, resulting in a thinner layer. Our hot-dipped pipes offer superior corrosion resistance for structural use. -
Q: Can you provide pipe with different wall thicknesses or lengths?
A: Yes, we offer customizable options. While 2.5mm thickness and 6m length are standard, we can produce pipes with wall thicknesses from 1.5mm to 12mm and lengths up to 12m, subject to minimum order quantity. Please contact our sales team for details. -
Q: Is this pipe suitable for underground water or gas applications?
A: This pipe is primarily designed for structural building applications. For water or gas transmission, we recommend checking local codes and using appropriate fittings. Our galvanized coating meets standard requirements, but always consult a professional engineer for specific use cases. -
Q: What certifications do you hold?
A: We are ISO9001:2025 certified, ensuring our quality management system meets international standards. We can also provide mill test certificates and third-party inspection reports (e.g., SGS, BV) upon request. -
Q: What is the typical lead time for an order?
A: For standard sizes (like 2.5mm x 6m), lead time is usually 15-20 working days after confirmation. For customized orders, it may be 25-30 days depending on quantity and specifications. We offer fast shipping via sea, rail, or air. -
Q: How do you ensure the quality of the galvanized coating?
A: We strictly follow ASTM A123 standard for galvanizing. Each batch is tested for coating thickness, uniformity, and adhesion. We also perform visual inspection and mechanical tests to ensure the pipe meets your requirements. -
Q: Can I order a small quantity for trial?
A: Yes, we accept trial orders. Minimum order quantity is typically 1 ton for stock sizes. Contact our sales team to discuss your needs. -
Q: What is the payment term?
A: We commonly accept T/T (30% deposit, 70% before shipment) or L/C at sight. For long-term partnerships, other terms can be negotiated.
