Rebar is the common name for cylindrical shaped steel bars with uniformly spaced protrusions called lugs or deformations. They are hot rolled from semi-finished steel called billets.
Rebars are predominantly consumed steel product of the construction industry and are used specifically for concrete reinforcement. Rebar creates tension in concrete to help hold it in a compressed state. Reinforced concrete gives infrastructure, buildings, bridges, houses, and other construction the necessary structural integrity.
