TMT means thermo-mechanically treated. These TMT steel bars are generally used material in construction for enhanced protection against earthquakes and other types of natural disasters. TMT bars are fully corrosion resistant and rust resistant, and these bars are mandatory to be used in coastal and humid tracts. It intensifies the durability for the longer period. Thermally mechanically treated Bars are fire- and heat-defiant, and it helps to prevent any hazard.
