There are many types of steel bars, such as common round steel bars, ribbed steel bars, torsion steel bars, etc., are widely used in various building structures, and steel bars mainly bear tensile stress in concrete. Due to the action of the rib, the deformed steel bar has greater bonding capacity with the concrete, so it can better withstand the action of external forces. The quality of steel bars plays a vital role in the safety of engineering projects.
