Steel Rebar

Rebar (short for reinforcing bar), also known as reinforcing steel, reinforcement steel and colloquially in Australia as reo, is a steelbar 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.

Originally concrete structures were unreinforced (e.g. the dome of the Pantheon, Rome, still standing since ~126 AD). Rebar has been used in construction since at least the 15th century; for example, 2500m of rebars were used in the Château de Vincennes.
