Our factory is equipped with Several large warehouses and freight yards, the storage quantity of steel products keeps above 10000 tons throughout the year.
The mechanical engineering workshops of our factory are all equipped with numerical central control ,Our factory has been constantly improving the platform construction, improving the quality of technical team,strengthening the invention of products category, formed complete R & D system and production quality management system, wined high reputation in the iron and steel industry.
Round steel is divided into three types: hot rolled, forged and cold drawn. The specification of hot-rolled round steel is 5.5-250mm. Among them: 5.5-25mm small round steel is mostly supplied in straight bars, which are often used as steel bars, bolts and various mechanical parts; round steel larger than 25mm is mainly used to manufacture mechanical parts and seamless steel pipe billets.
