Description

[0002] Screw thread steel is commonly known as reinforcing steel. Reinforcing steel refers to steel for reinforced concrete and prestressed reinforced concrete, and the cross section of reinforcing steel is circular, and sometimes is square with rounded corners. Reinforcing steel processing generally goes through four processes: reinforcing steel rust removal, reinforcing steel straightening, reinforcing steel cutting and reinforcing steel forming, and is mainly used for various large, heavy, light, thin-walled and high-rise building structures, and is divided into plain round reinforcing steel, ribbed reinforcing steel and twisted reinforcing steel. The reinforcing steel bending machine, as the name implies, is a machine for bending reinforcing steel.
