Advantages of cold rolled ribbed bar

1, the steel strength is high, can save construction steel and reduce the project cost. CRB550 cold rolled ribbed steel bar compared with hot rolled round steel bar, used in cast-in-place structures (especially in the roof) can save 35% to 40% steel. If you consider not to bend the hook, the steel saving is still more. According to the current steel market price, each ton of cold-rolled ribbed steel bar can save steel costs of about 800RMB.
2. The bonding and anchoring performance between cold rolled ribbed steel bars and concrete is good. Therefore, when used in the component, the phenomenon of cracking in the anchoring area of the component and the damage caused by the slip of the steel wire are fundamentally eliminated, and the bearing capacity and anti-cracking ability of the end of the component are improved. In reinforced concrete structures, the crack width is also smaller than that of circular steel bars or even hot-rolled thread bars.
3, the elongation of cold-rolled ribbed steel bar is larger than that of similar cold-processed steel.
