Product Description

Product Description

Zhengde Steel Round bar refers to a solid strip of steel with a circular cross section. Its specifications are expressed in millimeters of diameter, such as "50" means a round steel with a diameter of 50 mm. Steel Round bar is divided into three types: hot rolled, forged and cold drawn. The specifications of hot-rolled round steel are 5.5-250mm. Among them: 5.5-25 mm small round steel is mostly supplied in bundles of straight strips, which are often used as bolts and various mechanical parts; round steel larger than 25 mm is mainly used for manufacturing mechanical parts or seamless steel pipe billets.
The difference between steel Round bar and other steel bars: The shape is different. The shape of round bar is smooth and round, without grain and ribs. Other steel bars have grooves or ribs on the surface, which will cause the bond between round bar and concrete. Small, while other steel bars have a strong bond with concrete.
