TMT Bars

TMT BARS


The Thermo Mechanically Treated TMT Steel Bars is also known as reinforcement steel. Its high-corrosion and rust- resistance features make it the first choice for buildings in coastal areas and in areas of high humidity. Its ductility and bend ability makes it the perfect choice for buildings in seismic zones for high-stress construction structures.

Industry Usage

TMT Bars are primarily used by the construction industry. They also find wide application for a number of high-specialty and custom constructions such as concrete reinforcement structures like Homes, Apartments, Hospitals, Hotels, Auditoriums, Bridges, Dams, Flyovers, Thermal & Hydel Power Plants, Industrial Structures, High-rise buildings Earthquake-sensitive zones, Underground platforms in Metro Railways and Rapid Transport Systems etc.

Manufacturing Process

  • STAGE 1 - QUENCHING
  • STAGE 2 – SELF TEMPERING
  • STAGE 3 – ATMOSPHERIC COOLING

The reheated billet first gets rolled and is passed through the quenching process where the surface of the bar is instantly cooled while the core still remains hot.

Heat from the core of the bar dissipates to the surface allowing forming tempered external martensite, while the core remains austenitic. This process is called 'self-tempering." This process helps in attaining higher yield strength and imparts strength and toughness to the bars.

Due to atmospheric cooling, wherein the bar is cooled on the cooling bed, results in the austenitic core being converted into fine- grained pearlite core; which gives TMT its unmatched qualities of strength and high ductility.


Manufacturing Process

Our TMT Bars conforms to the following standards:

  • Fe-415
  • Fe-450
  • Fe-500
  • Fe-500D
  • Fe-550

We offer TMT bars in various sizes ranging from 6mm to 32mm. Global steels generally deals in TMT Bars, made from virgin steel, maintaining stringent tolerances both in chemistry & physical properties.
