Frequently Asked Questions
What is the difference between pre-galvanized and hot-dipped galvanized pipes?
Pre-galvanized pipes are made from steel strips that were galvanized before forming, typically with a zinc coating of 5μm-25μm. Hot-dipped galvanized pipes are submerged in molten zinc after fabrication, resulting in a much thicker coating of 35μm-200μm, providing better corrosion resistance.
Can I request specific sizes and lengths for the square pipes?
Yes, we offer a wide range of sizes from 10*10mm to 500*500mm and can customize the length and other specifications according to your project requirements.
What international standards do your products comply with?
Our galvanized pipes meet various international standards including GB/T6728-2002, ASTM A500 Gr.A.B.C, and JIS G3466. We are also ISO 9001 certified.
What are the typical shipping and delivery terms?
We offer flexible trade terms including FOB, CFR, CIF, DDP, and EXW. The standard delivery time is within 25 days after order confirmation, with a minimum order quantity of 2 tons.
Do you provide third-party inspection services?
Yes, we can supply BV (Bureau Veritas) or SGS inspection reports if requested by the client to ensure the highest quality standards are met.
What processing services can you perform on the pipes?
We provide various machining services such as removing welded stabs, pipe necking, hole punching, threading, and painting to suit your specific application.
