Frequently Asked Questions
Q1: What are the main differences between pre-galvanized and hot-dipped galvanized steel pipes?
A: Pre-galvanized pipes have a zinc coating thickness of 5μm-25μm and an outer diameter range of 1/2''-4'', which is suitable for lightweight structure and indoor applications. Hot-dipped galvanized pipes have a thicker coating of 35μm-200μm and outer diameter up to 24'', making them highly corrosion-resistant for outdoor environments.
Q2: Which international quality and production standards do your steel pipes meet?
A: Our products comply with major global standards including BS1139-1775, EN1039, EN10219, JIS G3444:2004, GB/T3091-2001, BS1387-1985, DIN EN10025, and ASTM A53. We are also ISO9001 certified.
Q3: Do you support customized machining for the steel pipes?
A: Yes, we provide multiple custom options like necking down, punching holes, removing internal or external welded stabs, threading, and specific end finishes.
Q4: What is the typical packing and container loading capacity for shipments?
A: Large OD pipes are shipped in bulk, while small OD pipes are bundled with steel strips and wrapped in woven cloth. A standard 20ft container carries up to 28mt (length ≤ 5.8m), and a 40ft container carries up to 28mt (length ≤ 11.8m).
Q5: What are your payment terms and minimum order quantity (MOQ)?
