Rebar also known as reinforcement steel and reinforcing steel, is a steel bar or mesh of steel wires used in reinforced concrete and masonry structures to strengthen and hold the concrete in tension. To improve the quality of the bond with the concrete, the surface of rebar is often patterned.
Steel bars are reinforcement rods used in concrete construction to provide tensile strength and structural support. Commonly known as rebar, these bars are essential in building foundations, columns, beams, and other load-bearing elements.
