How can I get the price? We usually quote within 24 hours after we get your inquiry by telling us the material, out diameter, wall thickness length, quantity and application of the steel pipe which you need. If you are very urgent to get the price, please inform us in email so that we will regard your inquiry priority.
|
| 3 |
How can I get a sample to check your quality? dimension will be much similar as your request but not same. And customer should afford the charge of shipment.
|
| 4 |
How long can I expect to get the sample? You can use your own consignee account or prepay us if you do not have an account.
|
| 5 |
What about the lead time for mass production? Honestly, it depends on the order quantity and the season you place the order.
|
| 6 |
What is the Small Qty Process Charge. It is the payment for customer whose order qty is less then Min Order Qty. Because small qty of products should be processed same in the production flow as big qty and the average cost would get much higher than big ones. So there is a small Qty Process Charge to ensure the profit of our factory and usually the amount of it is about $250.00

Could the pipe be customized for us? Pipe manufacturing.
We could print the logo and label under your requirements if you need OEM products. Beside this, we still do some refined processes like CNC cutting, chamfering, galvanization and tapping, if you have detailed spec or drawing.Our production lead time is within 30-45 days.

Galvanized Steel Pipe can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements.hot dip galvanized steel pipe, carbon steel seamless pipe/ seamless precision steel tube/ Automotive special steel has been used used for water-supply pipes or as a strong tubing for outdoor applications.
USHDJ
Galvanized Steel Pipe is most commonly used for outdoor construction like fences and handrails, or for some interior plumbing. hot dip galvanized steel pipe, carbon steel seamless pipe/ seamless precision steel tube/ Automotive special steel is also sometimes called galvanized iron pipe. Galvanized steel pipe has been coated with a layer of zinc. The zinc provides a barrier against corrosion so that the pipe may be exposed to the outdoor environmental elements.Galvanized Steel Pipe The protective barrier proves equally effective against damage from indoor humidity.hot dip galvanized steel pipe, carbon steel seamless pipe/ seamless precision steel tube/ Automotive special steel is covered with a zinc material to make the steel pipe more resistant to corrosion.
