TMT bar stands for “Thermo-Mechanically Treated” bar. It is a type of reinforcement steel bar used in construction for providing structural strength to concrete structures like buildings, bridges, and other infrastructure projects. TMT steel bars are used in the construction of slabs and beams, which are essential components of a building’s framework. Their high tensile strength and ductility ensure that these structural elements can bear the load of the building and distribute it evenly across the structure.
