Mild steel reinforcement refers to steel bars that are used as reinforcement in concrete structures. Unlike high tensile steel bars, mild steel has a lower yield strength and is more ductile, making it less resistant to tensile stress. However, mild steel is easier to bend and shape, making it suitable for applications where a certain level of flexibility is required. It is also more readily available and less expensive than high tensile steel. Mild steel reinforcement is commonly used in residential and low-rise construction, where the stress levels are lower and the cost of high tensile steel is not justified.
