Real TMT bars are widely used in everyday use concrete reinforcement structures, skyscrapers, bridges and flyovers, dams, thermal and hydel power plants, industrial structures, underground platforms in metro railway and rapid transport system. TMT Bars are thermo-mechanically-treated through leading world tempcore-based technology for high yield strength. The process involves rapid quenching of the hot bars through a series of water jets after they roll out of the last mill stand. The bars are cooled, allowing the core and surface temperatures to equalize. The bar core cools down slowly to turn into a ferrite-pearlite aggregate.
