Steel bars are commonly used as reinforcement to impart tensile and shear strength to the structure since concrete is weak in tension/shear. Steel is widely used as reinforcement because its coefficient of linear expansion is close to concrete. Steel reinforcing bars (Rebar) are manufactured through a hot rolling process with subsequent treatment (controlled cooling and tempering). Rebars produced by Tata Steel Limited are in sizes from 6mm to 40mm. Primary application of rebar is to strengthen concrete in end-use applications like buildings, bridges, metros, dams, thermal power plants, liquid retaining structures etc.
