Steel Reinforcement ( Rebar )

Rebar (short for reinforcing bar), known when massed as reinforcing steel or reinforcement steel,[1] is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and aid the concrete under tension. Concrete is strong under compression, but has weak tensile strength. Rebar significantly increases the tensile strength of the structure. Rebar’s surface is often “deformed” with ribs, lugs or indentations to promote a better bond with the concrete and reduce the risk of slippage.
