What is rebar?

Explanation:
Rebar is steel reinforcing bar placed in concrete to increase its tensile strength. Concrete handles compression well but is weak in tension, so embedding steel bars helps the structure resist pulling and bending forces, preventing cracks and failure. You’ll find rebar in foundations, slabs, beams, and walls, often with ridges to improve bonding with the concrete. It’s not electrical conduit, insulation, or plywood.
