Product Descriptions
We have kept a long-term partnership with a few well-known steel manufacturers for many years. Raw material source is stable, and the quality is guaranteed.
Specifically, 1) Black Hot Rolled Coil:
Shougang Group;
Hebei Iron & Steel Group( Yanshan Steel Corporation);
Lingyuan Iron & Steel Group Co., Ltd.;
Jinxi Group;
Rockcheck Group;
Delong Steel Co., Ltd and etc.
Our products all have pretty physical appearance with smooth outside welding. Compared with some other suppliers, we use a flat knife for scraping the weld line. Besides, the visual weld geometry size is in line with the actual requirements of different applications. On the other hand, tube shape mutation is easy to cause stress concentration. If the excess part of the welding is polished off in the pipe production process, this will somewhat eliminate part of the stress concentration. In addition, our workers are all skilled in the post treatment of pipes, who all have excellent professional experience for many years.
