The Bendability of TMT Bar and Rebar is such a feature that makes it loved by all in the industry. Construction of a house needs proper planning and adequate strength which can withstand the load of the building and natural disasters too. So in order to deliver such strength and flexibility, steel TMT Bar and Rebar are majorly used. This is because strength and flexibility are important for an ideal TMT Bar.  

Thermo Mechanically Treated (TMT) steel reinforced bar is majorly known for its absolute strength and ductility. Making of TMT Bar is an innovative procedure performed on the hot rolled steel bars, which results in a strong surface outer which deals with the tensile strength and a soft inner core which deals with the ductility factor. Also one should know the production process of stainless steel and the full manufacturing process of TMT Bar and Rebar.   TMT reinforced steel bars are very much known for its bendability.

If you want to select top quality TMT bar for construction purposes in the state of Rajasthan, then visit AV Steel which is the authorized dealer of Birla TMT Bar and Rebar.

While purchasing TMT Bar avoid certain common mistakes and also take care of certain points while buying TMT Bars and Rebar.

Ductility and Bendability

Bendability is considered as an important factor of TMT reinforced steel bar because it requires scenarios where it must be bent as per the building design. Most of the people are not aware of the importance of ductility in TMT Bar and TMT rebar, all they care and know about is the high tensile strength of the steel TMT rebar. High strength increases the capability of TMT Bar to withstand more load and ductility determines the capacity of bending the TMT bar. Thus, strength and flexibility become important for ideal TMT Bar.

A Rule of Thumb says more ductility results in more bendability of the TMT reinforced bars. TMT reinforced bars are available in many grades namely Fe415, Fe500, Fe 550 and Fe 600. The numbers represent the minimum yield strength of each TMT reinforced bars. The higher grades can be achieved by making slight minor changes in the original TMT process. This results in producing reinforced steel bars with more strength. Also the thermal resistance of TMT Bar is really good. In the state of Rajasthan, AV Steel provides the best and top quality Birla TMT Bars being the authorized seller of TMT Bar and Rebar in the state. So, if you are looking for the best quality TMT Bar, then AV Steel is the solution.

Effect of Low Ductility on Bendability

Less ductile TMT bar means that the rebar is more prone to breaking. Generally, TMT reinforced bars are bent using a universal bending machine which ensures that the rebars are bent perfectly rather than manually bent by the laborers. Whenever a less ductile steel TMT bar is bent, the chances of it breaking are high than bending a reinforced steel bar with optimal ductility. An ideal TMT bar should also be corrosion-resistant. You can go through the tips to make steel and TMT Bars corrosion-free.

Low ductility makes the reinforced bars more prone to natural disasters, particularly earthquakes. Know the tips to save the building from the earthquake. The ductility of the core of the TMT Bar is reduced as the tensile strength of the TMT Bar is increased. Thus, this makes them brittle and makes the higher grade bars less supportive of any sudden underground seismic vibrations i.e earthquakes.

When we talk about bendability, higher grades TMT Bars do not bend easily as compared to lower grades because of less ductility and high strength. Moreover, the process of bending higher grade TMT reinforced bars should be done very slowly and without any sort of jerking. Hydraulic bending machines must be used for the bending process. It is always suggested to preheat the high-grade TMT Bar before bending. Also, you can go through the interesting facts about steel.


Out of the varied range of TMT reinforced bar grades, Fe 415 is the only grade having the optimal and ideal tensile strength and ductility. Thus, Fe 415 has high bendability as compared to others but that doesn’t degrade the other grade TMT bars. Higher grades TMT Bars are used for constructions according to its requirement.For any of your queries or demands, contact here.
