he specially formed steel which is placed in the concrete with the aim of meeting the shear stress and tensile stress is called as reinforcing bar. It is generally manufactured as 12 meters long. The ribs on its surface are manufactured by twisting in the cold and the possibility of taking it out the concrete by stripping is very low. It has a wide range of thicknesses depending on desired resistance.
The reinforcing bar is manufactured by quench tempering and hot rolling production processes
