What Are TMT Rods?


TMT stands for Thermo-Mechanically Treated, which refers to a process that combines heat treatment and mechanical twisting to enhance the strength and flexibility of steel bars. These rods are the backbone of modern infrastructure, providing the necessary tensile strength to withstand various stresses.


Understanding the Basics of TMT Rods and Their Importance in Construction

What Are the Features of AMBA Shakti SD TMT Bars?


AMBA Shakti SD TMT Bars are known for their super ductility, making them earthquake resistant—a critical property in regions prone to seismic activity.

Key highlights include:


  • Controlled raw material and no twist straight mill rolling ensure no distortion in bars.

  • Master bundle of 3 MT minimizes pilferage.

  • CNC notching for uniformity in steel and better bonding with cement.

  • HSS rolls improve production, pass life, and surface finish.

  • Full automation leads to better quality control and productivity.

  • Hot charging technology (instead of RF Furnace) saves production costs with significant energy savings.

  • PLC-based controls ensure precision in the manufacturing process.

  • Sand filtration plant ensures cleaner water for the TMT quenching process, resulting in higher roll life and better finish.

  • Approx. 20% cost savings compared to local steel.

  • Manufactured using Thermax® Patented Technology under expert supervision.



What Are the Salient Points of AMBA Shakti Flexion TMT Bars?


AMBA Shakti Flexion TMT Bars share all the features of the SD variant but come with additional benefits:


  • Designed to compete with primary steel manufacturers at a lower cost.

  • Produced through the Ladle Refining Furnace (LRF) route, refining steel and removing tramp elements.

  • Enhanced tensile strength, yield strength, and elongation.

  • Superior earthquake resistance, making them ideal for critical and complex structures like:

    • High-rise buildings

    • Dams

    • Airports

    • Megastructures
