Frequently Asked Questions
-
What is the difference between hot-dip galvanized and pre-galvanized pipe?
Hot-dip galvanized pipe is dipped in molten zinc after fabrication, resulting in a thicker coating (200–600 g/m²). Pre-galvanized pipe is made from already galvanized steel coil, giving a thinner coating. For outdoor or heavy-duty use, we recommend hot-dip galvanized. -
Do you provide a Mill Test Report (MTR)?
Yes, every shipment includes a Mill Test Report that details chemical composition, mechanical properties, and test results. It ensures full traceability and compliance with standards. -
Can I get custom lengths and threaded ends?
Absolutely. We can cut pipes to any length between 1 m and 12 m. Threaded ends with coupling are available upon request. -
What is the minimum order quantity (MOQ)?
Our standard MOQ is 5 tons for common sizes, but smaller trial orders can be arranged for new customers. Please inquire with our sales team. -
How long does shipping take to the US or Europe?
Shipping time depends on the port of destination. From Qingdao to major US ports takes approximately 25–35 days; to European ports about 30–40 days. We can provide estimated transit time after order confirmation. -
What payment terms do you accept?
We accept T/T (30% deposit, 70% before shipment) and L/C at sight. Other terms may be negotiable for regular customers. -
Is the 12-month warranty valid for all applications?
The warranty covers manufacturing defects under normal usage conditions. It does not cover damage from improper installation, external corrosion due to aggressive chemicals, or misuse. Please refer to our warranty policy for full details. -
Do you offer free samples?
Yes, we can provide small free samples (up to 1 meter) for quality evaluation. The customer covers shipping cost. Contact us to arrange.
