TMT Bars

Strength of the bars are carefully controlled by optimizing the water pressure for their

pearlitic core and tough surface of tempered martensite, thereby providing an optimum strength, ductility

and toughness. TMT bars are widely used in general purpose concrete reinforcement structures, bridges and

flyovers, dams, thermal and hydel power plants, industrial structures, high-rise buildings, 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

ferrlite-pearlite aggregate.
