Deformed Rebar, also known as reinforcing bar or rebar, is a crucial construction material characterized by its surface deformations—ribs, lugs, or indentations—which are rolled onto the bar during the manufacturing process. These deformations create a strong mechanical bond when the rebar is embedded in concrete, preventing slippage and ensuring that the concrete and steel act as a single composite unit to resist tensile forces. Widely used in concrete structures from foundations and slabs to beams and columns, deformed rebar significantly enhances the tensile strength and overall structural integrity of buildings, bridges, and infrastructure, effectively preventing cracks and ensuring long-term durability.
