TMT ReBars

We are one of the leading manufacturers and suppliers of a comprehensive range of  TMT Rods.

Fe stand for ferrous and 500 denotes the yield stress in MPa.(N/mm2) Good quality TMT have bar impurities like Sulphur and Phosphorous below 1%. These impurities decrease the TMT bars strength in extreme cold and hot conditions.Fe 500 grade TMT steel bars . Fe 500 TMT steel rebars are manufactured using latest technology and stringent Quality Check (QC) measures. High quality off-cuts are processed in the most sophisticated Induction Furnace and Ladle Refining Furnace, a proven technology to produce high quality clean TMT steel with least traces of chemical elements like Sulphur and Phosphorus.

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. Narayani Ispat Pvt Limited, unit has been authorized to manufacture Tempcore TMT under licence agreement.
