Steel bar reinforcement, often called rebar for short, consists of steel bars with patterned deformations running along their length. These deformations are crucial for creating a strong bond with the surrounding concrete. Rebar is embedded in a strategic grid within concrete elements like beams, slabs, and columns. Concrete is exceptional at withstanding compressive forces (pushing down), but weak in tension (pulling apart). The rebar acts like an internal skeleton, taking on the tensile forces and preventing cracks from forming.

This significantly enhances the overall strength and load-bearing capacity of the concrete structure. Buildings, bridges, and other structures rely on steel bar reinforcement to ensure stability and safety under heavy loads.
