Deformed bars, also known as rebar, are steel bars with surface deformations like ribs or indentations, designed to enhance their bond with concrete in reinforced concrete structures. These deformations improve the grip and friction between the steel and concrete, preventing slippage and increasing the overall strength and durability of the structure.
Steel bars have high yield strength and tensile strength, and can withstand large external forces without deformation or breakage. This high strength property enables them to be used as heavy-load structural components in the fields of construction and machinery manufacturing. For example, in construction, reinforced concrete structures rely on the high strength of steel bars to resist the various loads imposed on the building and ensure the safety of the building.
