TMT BARS

TMT BARS

TMT bars or Thermo-Mechanically Treated bars are high-strength reinforcement bars having a tough outer core and a soft inner core. The very first step of the manufacturing process involves passing the steel wires through a rolling mill stand. Thereafter, these rolled steel wires are again passed through the Temp core water cooling system. While passing the wires through the water cooling system, the water pressure is optimized. The sudden quenching and drastic change in temperature toughen the outer layer of the steel bar, thus making it super tough and durable. Once this process is over, the TMT bars are subject to atmospheric cooling. This is done in order to equalize the temperature difference between the soft inner core and the tough exterior. Once the TMT bar cools down, it slowly turns into a ferrite-pearlite mass. The inner core remains soft giving the TMT bar great tensile strength and elongation point. This design is unique to the TMT bars and gives superior ductility to the bars. Also, this unique manufacturing technique and the absence of Cold stress make this bar corrosion-resistant and boost its weld ability.

Hence, TMT Bar is the one and only choice in Construction industry for it’s
  • Ductility
  • Tensile Strength
  • Yield Power
  • Thermal Resistance
  • Corrosion Resistance

Types:

We mainly deal in 2 types of TMT bars which fall under different grades, namely Fe 500 and Fe 550.
  • Fe 500 grade

    Fe500 grade is generally regarded as a market-standard across many construction projects. Variations in Fe500 are Fe 500D and Fe 500S, are also popular choices which offer greater seismic stability and ductility.

    Uses :
    • Fe 500 bars can be used across a range of residential, commercial and multistorey projects.
    • They offer greater tensile strength and greater ductility than Fe 415 which are specially manufactured to provide stability to high-rise projects, while resisting load better.
    • These bars are used in the area where there is high seismic activity and sudden loads.
  • Fe 550 grade

    Because of the greater tensile strength, Fe 550 grade bars can be used across a range of large-scale projects.

    Uses :
    • These are used for developing industrial and large-format infrastructure projects like brides, industrial projects and structures requiring high load-bearing capacities
    • These bars are especially impactful in coastal, marine and underground environments as well.

Generic USES:

  • Power Plants
  • Dams
  • Airports
  • Bridges
  • Flyovers
  • Stadiums
  • Highways
  • High Rise Construction
  • Complex Structures
