Why choose our hot-dip galvanized round tube? The hot-dip galvanizing process creates a metallurgical bond between the zinc and steel, offering sacrificial protection that lasts decades in normal environments. Our pipes are tested for tensile strength, elongation, and leak resistance to ensure they perform reliably under pressure. Additionally, the smooth interior surface minimizes friction loss in fluid transport, making them ideal for water, gas, and oil lines.
Applications include:
- Water supply and distribution systems
- Construction scaffolding and structural supports
- Fencing and handrails
- Agricultural irrigation
- Industrial piping (compressed air, steam, etc.)
- Fire protection sprinkler systems
Our factory in Liaocheng, Shandong, employs advanced production lines and a strict quality management system certified under ISO9001. From raw material inspection to final packaging, every step is monitored to ensure you receive defect-free pipes. We also offer flexible packaging options: bundled with steel straps, in loose coils (for smaller diameters), or with protective caps for threaded ends.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between hot-dip galvanized and pre-galvanized pipes?
A: Hot-dip galvanizing (HDG) involves immersing the steel in molten zinc, forming a thicker, more durable coating. Pre-galvanized pipes are coated with zinc before cutting and forming, which can leave exposed edges. Our HDG pipe offers superior protection for outdoor and corrosive environments. -
Q: Can you provide pipes with threaded ends?
A: Yes, we offer threading per BS 21 (BSPT) standard. Please specify when ordering. Threaded pipes are supplied with plastic caps to protect the threads during transport. -
Q: What is the minimum order quantity (MOQ) for 2-inch and 4-inch pipes?
A: Our standard MOQ is 5 tons per size, but we can accommodate smaller trial orders for new clients. Contact our sales team for details. -
Q: How long is the delivery time?
A: Typical lead time is 15–25 days after deposit, depending on quantity and customization. We maintain a ready stock for common sizes (2-inch and 4-inch, 6m length) to expedite urgent orders. -
Q: Are these pipes suitable for underground water supply?
A: Yes, the hot-dip galvanized coating provides excellent corrosion resistance against soil and moisture. For highly corrosive soil, additional wrapping or coating may be recommended – consult our technical support. -
Q: What certifications do your pipes have?
A: Our factory is ISO9001 certified, and our pipes comply with BS 1387. We can provide test certificates for each batch, including chemical composition and mechanical properties. -
Q: Can I get a sample before placing a bulk order?
A: Absolutely. We offer free samples for small quantities (shipping cost may apply). Contact us to arrange a sample of 2-inch or 4-inch pipe. -
Q: How do you package the pipes for export?
A: Standard packaging includes steel strapping, waterproof plastic wrapping, and wooden pallets or crates for added protection. We also offer custom packaging solutions upon request.
