Rebar (short for reinforcing bar), also known as reinforcing steel, reinforcement steel[1] and colloquially in Australia as reo, is a steel bar or mesh of steel wires used as a tension device in reinforced concrete and reinforced masonry structures to strengthen and hold the concrete in tension. Rebar's surface is often patterned to form a better bond with the concrete.


Stirrups form the outer part of a rebar cage. Stirrups are usually rectangular, and are placed at regular intervals along a column or beam to prevent shear failure
