Busting the Myths Around TMT Steel Bars in India

Thermo Mechanically Treated bars | SEL Tiger

Everyone has an opinion today, but without checking the facts, the opinions turn into myths, and that clouds the judgement of buyers, to make a big decision such as investment in TMT bars. So, if you are reading this, it is possible you may have heard a few myths about steel bars in India, and it’s time to bust the myths one by one. SEL Tiger is the leading steel brand and TMT bar supplier in India, and with our expertise and industry knowledge, we are set to debunk every myth associated with TMT (Thermo-mechanically treated) bars.

Myth: Steel Bars are Susceptible to Corrosion

Corrosion is an absolute threat to construction, as it degrades the quality of the building from its core. Well, it is a myth that most people are not aware of.  In reality, the controlled quenching process during manufacturing forms a layer of tempered martensite on the surface of the bars, providing excellent corrosion resistance. This unique property makes TMT bars ideal for use in diverse environmental conditions, including coastal areas where corrosion is a significant concern.

Myth: The TMT Bar Is Not That Strong

The steel TMT bars are stronger than traditional steel bars. In the SEL TMT bar, with our research and technology, we have understood how to make the Thermo mechanically treated bars better for concrete reinforcement. The unique rib design gives maximum rib area (AR) value, that ensures a strong and long-lasting Tiger Bond with concrete. Other than that, the bars are manufactured with German Thermex Technology which undergoes thermo mechanical treatment making the bars strong and tough from the outside, while the inside is soft, allowing it to be flexible, and resistant to cracks.

Myth: Weldability of the bars

There is a misconception that the heat treatment involved in manufacturing of the bars affects the weldability of these bars. However, TMT bars are specifically designed to exhibit superior weldability, allowing for the creation of strong and durable joints in construction projects. Our Fe 550 D grade steel bar’s unique microstructure, characterized by a tough outer layer and a softer inner core, facilitates efficient welding without compromising the overall strength of the structure.

Myth: TMT bars are not suitable for coastal areas

Coastal areas are often associated with high humidity, and salt-laden air that increases the risk of corrosion. As TMT bars from leading TMT bar manufacturers and suppliers come with corrosion-resistant properties are well-suited for coastal regions. The protective oxide film formed during the manufacturing process helps mitigate the impact of salt exposure, making TMT bars a reliable choice in such environments.

Myth: TMT Steel Bars are not budget-friendly

The initial cost of TMT bars is a little higher than steel bars, however, in the long run, it is cost-friendly. TMT bars from SEL Tiger have a dense rib design in the bars, which decreases the number of TMT bars required for framing the beams or concrete structures, moreover, it also reduces the labour charges, as less installation is required than traditional steel bars. Another factor that makes them cost-efficient is TMT bar’s durability, and low maintenance makes them a cost-efficient choice in the long run, proving that the investment is well worth it.


In conclusion, thermo mechanically treated bars, particularly Fe 550D bars, play a pivotal role in shaping the landscape of the Indian steel industry. By debunking common misconceptions and highlighting their numerous advantages, it becomes evident that TMT bars are a reliable and indispensable component in various construction projects. The superior properties of Fe 550D bars, including high tensile strength, superior ductility, and enhanced corrosion resistance, position them as a preferred choice for diverse applications, ranging from high-rise buildings to industrial structures.

Being leading Fe 550 D TMT bar supplier, at SEL Tiger our TMT bars are designed to debunk all the myths associated around steel bars. Regardless of cold breeze, coastal winds, seawater, humidity, and any other weather condition, TMT bars can withstand the test of time. Interested in purchasing? Then contact us to get a quote!

Frequently Asked Questions

1. How flexible are TMT bars in terms of bending and welding?

TMT bars are designed to be flexible and can be easily bent or shaped in any form without any loss of strength. These bars are manufactured after sentring, quenching, and heat treatment which makes the inside of the TMT bar soft, allowing it to be weld easily, and provide flexibility when added in reinforced concrete structures.

2. What properties of Thermo mechanically treated bars make it suitable for earthquake-resistant?

TMT bars are an excellent choice for earth-quake resistant construction. SEL Tiger is a leading TMT bar manufacturer and supplier, and to remove the misconception that steel bars are susceptible to corrosion, we use corrosion resistant elements that includes Chromium, Copper, and Phosphorus. With a three-step process of quenching, self-tempering, and annealing, we manufacture corrosion resistant bars.

3. Do TMT bars come with Zinc Coating for Corrosion Resistance?

All TMT bars do not have Zinc coating, however steel bars which are used in marine construction, or industrial applications, or used in areas with high salinity are customised with Zinc-coating.

4. Is TMT bar costly than steel bars?

Traditional steel bars are cost-inexpensive than TMT bars, however, in long run they require maintenance, and are susceptible to damage, whereas TMT bars are designed to withstand such circumstances. The cost might be higher than steel bars initially, but over time it reduces the carry-on expenses.
