Technology used in Radha TMT

HYDERABAD’S LARGEST HI-SPEED UNIT

Radha TMT Production Unit


Our state of the art high-speed continuous rolling mill ensures that loop doesn’t get formed and strength, form, shape & diameter is maintained across the entire length of the bar conforming to BIS standards. We follow industry standards for primary steel manufacturing to ensure top quality and consistent mechanical properties.

PRECISE RIBS FOR BETTER BONDING

Our rolling mill is equipped with an automatic Sparkonix CNC machine for even spaced and precise depth rib cutting. This machine is capable of cutting ribs at any angle or even enlarging ribs. Due to uniformity and precision of ribs, the anchorage between steel and concrete will be stronger. In addition, the load distribution will be uniform across the entire length of TMT bar making the structure stronger.


STRINGENT TESTING & QUALITY CONTROL

To ensure consistent quality, the physical & chemical properties of the TMT bars are tested in the Universal Testing Machine while the chemical composition of the raw material (MS Billets) is scrutinized by the Spectrometer. This is achieved through pre-defined and random sample tests at every stage of the manufacturing process.

CUTTING-EDGE TECHNOLOGY

Strong and resilient Thermo Mechanically Treated RADHA 550 (TMT) Bars Radha 550 TMT bars delivers exactly what builders, architects, and consultants need – the strength, durability, and resistance of steel. The superior quality of Radha 550 TMT bars, Manufactured using THERMEX (also known as 'Quenched and Tempered rebars’), is a result of four key factors:

  • High quality primary raw material - MS Billets.
  • Fully automated hi-speed rolling mill.
  • German-designed quenching and tempering technology.
  • Stringent testing and quality control process.

We ensure that our TMT bars not only meet the highest quality specifications but also suit the tropical conditions of a region.

Water quality

Dissolved solids and hardness in water impacts quality of TMT bars. Impurities in water get deposited on the surface which accelerates oxidation process resulting in rusting of bars quickly. That is the reason why we treat and purify water in our unique treatment plant and only such water is used to quench Radha 550 TMT bars giving it anti-corrosive properties.

What makes Radha 550 TMT bars extraordinary is the specialized 3 stage manufacturing process involving Thermo Mechanical Treatment of the bars.

TMT Bars Processing Chart

Stage 1

The rolled bars are subjected to a specially designed water cooling system which renders the outer surface of the bars cold while retaining the heat within the core

Stage 2

Heat from the core of the bar dissipates to the surface of the bar creating a temperature gradient in the bars forming martensite on the surface while retaining the ferrite, pearlite structure in the core. This process is called “self-tempering”.

Stage 3

This unique combination of ferrite, pearlite at the center, and martensite on the surface gives Radha 550 TMT Bars a higher yield strength coupled with higher elongation and finer ductility.
