Reinforcing Bars / Deformed Bars
Rebar (short for reinforcing bar ), known when massed as reinforcing steel or reinforcement
steel , 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.
The most common type of rebar is carbon steel, typically consisting of hot-rolled round bars with
