Thermo-Mechanically treated bars, popularly known as TMT bars are the most common construction materials used in many construction projects worldwide. These are highly preferred due to their superior strength and strong bonding with the concrete.
Let’s take a look at a few interesting facts about TMT bars:
High Strength bar
TMT bars are Thermo-Mechanically treated through a unique Tempcore technology that delivers a high strength to these bars. This process involves quick quenching of the extremely hot steel bars just after they roll out from the rolling mill. The bars are made to pass through a sequence of water jets which turns their outer layer extremely hard leaving their inner core soft. This makes the TMT bars highly ductile and makes them extremely strong. If you want to buy TMT bars, check the bars from SRMB, one of the topmost TMT bar manufacturers in India.
Corrosion Resistant properties
During the manufacturing process of the TMT bars, these bars are never twisted like the steel bars of yesteryear. This makes the TMT bars devoid of any residual stress. Moreover, during the quenching process of the TMT bars, the controlled water-cooling prohibits the formation of coarse carbides which is the main reason behind the corrosive process of the steel bars. This makes the TMT bars resistant to corrosion. During construction of houses or any other structure, the TMT bars are exposed to water for longer periods but rust never forms on the surface of the TMT bars. Corrosion is a common issue in case of ordinary steel bars. And that is why using ordinary steel bars can endanger the safety and security of the structure.
TMT bars have high ductility. You will get TMT bars in a number of grades such as Fe- 415/500/550. These TMT bars are stronger than ordinary steel bars. And that is why all the major construction projects use TMT bars for their construction.

They have flexible bending ability
TMT bars have extremely high bending ability. And that is the reason TMT bars allows ease of use. One can easily mould the TMT bars in various shapes. Also, these can be stretched to meet the unique demands of construction measurements.
TMT bars are earthquake-resistant
Do you know that TMT bars are resistant to an earthquake? These bars have soft inside and tough outer layer. Also, these have superior elongation which makes it extremely flexible. This, in turn, gives high flexibility to the concrete structure. The fatigue resistance property of the TMT bars enables them to bear seismic loading. And that is why TMT bars are highly preferred and recommended for construction in areas that are prone to earthquake.
Also, TMT bars have thermal resistant properties which make them a safe choice for fire hazards. We hope that these points will help you understand the unique features of TMT bars.
