REBAR
Rebar is a steel bar or mesh used to strengthen concrete and masonry structures. It enhances their ability to withstand both compressive and tensile forces. Rebar is widely employed in construction projects such as buildings, bridges, highways, retaining walls, tunnels, and foundations. Proper placement and configuration of rebar ensure structural integrity and safety.
