Solid Grip on RCC

Rollers incorporated for the manufacture of SEL TMT Bars Re-rolling mill operations are produced and curated through automated CNC machines for Accurate & Perfect Ribs as well as Added Casting Grip when added with Reinforced Concrete Cements.

Resistance to Fire & Corrosion

With the combination of a proper quenching system and steel, SEL TMT Bars are immune to impacts from harsh external weathers and corrosion. Our TMT bars are also tested fire resistant upto the temperature range of 600°C to 650°C.

Resistant to Earthquake

With earthquakes being one of the prominent concerns, our TMT bars contain a fine combination of Manganese and Carbon which is set at 0.42% making the bars highly bendable and offer higher elongation to prevent your constructions from any threats from earthquakes.


With the application of Fe415 and Fe550D, we ensure that you save about 3 to 4% in your TMT Bar purchases. This also ensures savings in steel usage up to 17% making TMT Bars unifor and lower section weights to ensure sustainability.

The integration of quality control and manufacturing facility processes further ensure higher product quality for our products making us one of the best TMT bar manufacturing companies in east India.
