Reinforcing steel, commonly referred to as steel rebar, serves as a crucial tension component in reinforced concrete and masonry structures, reinforcing and fortifying the concrete against tension forces. While concrete excels in compression strength, its tensile strength is comparatively low. Rebar plays a pivotal role in enhancing the overall tensile strength of the structure. Featuring a textured surface with continuous ribs, lugs, or indentations, rebar promotes optimal adhesion to the concrete, minimizing the risk of slippage.

The predominant type of rebar is typically made of carbon steel, manifested as hot-rolled round bars exhibiting deformation patterns on their surfaces. Notably, carbon steel rebar is chosen for its compatibility with concrete regarding thermal expansion coefficients, ensuring minimal stress differentials during temperature fluctuations.

Alternative rebar options include stainless steel, as well as composite bars composed of materials like glass fiber, carbon fiber, or basalt fiber. To mitigate corrosion effects, particularly in saltwater environments, carbon steel rebar may undergo coating with zinc or an epoxy resin. Surprisingly, bamboo has demonstrated viability as an alternative to traditional reinforcing steel in concrete construction. Although alternative types may incur higher costs or possess inferior mechanical properties, they find application in specialized construction scenarios where their unique characteristics fulfill specific performance requirements not met by carbon steel.
