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's best 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.

Features of TMT Bars

• Enhanced strength combined with high ductility
• Excellent weldability without loss of strength at welded joints
• Better ductility and malleability
• Earthquake resistant
• High thermal resistance
• Significant savings in cost of steel
