TMT bars or Thermo Mechanically treated bars are metallic rods widely used in the construction sector as reinforcements for concrete structures. These rods have high strength and ductility. TMT bars have a tough outer region and a soft inner core that impart high tensile strength and elongation point. TMT bars also have good weldability.
TMT bars are made by rolling steel wires and passing them through water whose pressure at an optimal pressure. The cooling creates a hard outer surface while the inner core is soft.
They are used in the constructions of houses, bridges, dams, etc. They have high thermal resistance and can withstand high temperatures.
