Final supply conditions:
Designation | Symbol | Description |
Cold finished (hard) | BK | Tubes do not undergo heat treatment following the final cold forming and, thus, have a rather high resistance to deformation. |
Cold finished (soft) | BKW | The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding). |
Cold-finished and stress-relieved | BKS | Heat treatment is applied following the last cold-forming process. Subject to appropriate processing conditions, the increase in the residual stresses involved enables both forming and machining to a certain degree. |
Annealed | GBK | The last cold-forming process is followed by annealing in a controlled atmosphere. |
Normalized | NBK | The last cold-forming process is followed by annealing above the upper transformation point in a controlled atmosphere. |

FAQ
Q: What product information must I provide before making a purchase?
Please provide the grade, width, thickness, and surface treatment requirements, as well as the quantities you require.
Q: What shipping ports are there?
We normally ship from Shanghai,Tianjin, Qingdao, and Ningbo ports
Q: Is it possible to send samples?
Of course, we offer free samples and express shipping to customers all over the world.
Q: Do you offer a service for customized products?
Yes, we can produce according to your specifications and drawings.
Q: Can I pay you a visit at your factory?
Customers from all around the world are welcome to visit our factory.
Q: Can you assist me in importing steel products for the first time?
Yes, we have shipping agent who will arrange the shipment with you.
Q: Do you have any MOQ limit for production?
We don’t have any MOQ limit. But as for our steel pipe product, we usually use container transport for lower freight. In the case of express delivery, high freight charges will be generated.
Q: Is it OK to print my logo on the product or the carton packing?
Yes. Please inform us formally before our production and confirm the design firstly based on our sample.
Q: How to pack the product?
The inner layer has a waterproof paper outer layer, iron packaging, and is fixed with a fumigated wooden pallet. It
can effectively protect products from corrosion during ocean transportation
