Radha TMT launches South India’s first Infrastructure Steel


Radha TMT ® 550D LRF Steel Rebars, the very first in South India, are made using advanced LRF Technology which ensures higher ductility and greater strength.

These Steel Rebars not only have good bonding properties to concrete but also highly durable. Here are a few reasons why it makes a perfect sense to choose Radha TMT® 550D LRF Rebars:

Only high-quality raw materials used

Fully automated high-speed mill

Superior LRF Technology

German Quenching and Self-tempering technology -THERMEX®

Stringent testing and quality control system

With such technology and processes in place, one can rest assured that every single TMT Rebar from Radha Smelters’ plant bears the distinct Radha stamp of quality and reliability.

Radha TMT® 550D LRF is all set to create new benchmark and achieve the status of being the preferred brand of every leading Builders, Architects and Structural Engineers across the country.

In Radha TMT® 550D LRF, “550” stands for minimum yield stress. The letter “D” denotes Ductility which means that the Steel Rebars have a higher percentage of elongation that offer greater resistance to natural calamities and other stress factors.

Radha Smelters use the clean Iron ore as primary raw material and deploys world class LRF and Thermex as the process technologies to produce the highest quality of 550D grade of TMT Rebars in 8mm to 32 mm sizes.

Ladle Refining Furnace (LRF) Technology LRF or Ladle Refining Furnace technology is used to improve the quality of liquid steel through refining, purifying and fine-tuning of its chemistry.

This process requires additional heat. Therefore, the ladle is provided with electrodes which heat the liquid metal and minimize thermal losses.

Inside Ladle Refining Furnace In LRF, the liquid metal is refined and purified by lowering the Sulphur, Phosphorous and dissolved Gases levels and homogenized in terms of temperature and chemical composition as per stringent BIS norms to provide the ideal strength and flexibility to the TMT Rebars.

Inclusions are also removed to ensure that steel is of the highest quality and exhibits superior mechanical properties
