Rebar (short for reinforcing bar) is also known as reinforcing steel, high tensile steel bar or deformed bar, and is commonly used to provide reinforcement or additional strength to concrete and masony structures. Cured Concrete is dense and performs well under compressive loads but is relatively weak in tension. To counter this imbalance, Rebar components are cast into the concrete to carry the tensile loads. Rebar is usually produced from carbon steel and formed with ribs for better mechanical anchoring into concrete.
