Highlighting Some Of The Frequently Asked Questions About TMT Bars

January 21st, 2021

It is needless to mention that Thermo Mechanical Treatment (TMT) bars are one of the most widely used construction materials in the world. The true strength of the best quality TMT bars lies in the optimum balance between ductility and flexibility.

Here we have highlighted some of the most frequently asked questions (FAQs) about TMT bars

What is Thermo Mechanical Treatment?

Thermo Mechanical Treatment is the process of heating and cooling TMT bars. It is a process by which high strength reinforcement steel bars or TMT bars are manufactured. It is an architectural process that involves hardening and heat treatment into a single process. It starts with the process of quenching which softens the core of the steel bars and hardens the outer surface. This process increases the tensile strength and ductility of the TMT bars.

What are the uses of TMT bars?

TMT bars are currently the most widely used steel reinforcement bar in the field of construction. The best quality TMT bars from the leading TMT bar companies in India features high-strength, fine bond with concrete, durability, thermal compatibility, etc. Due to this TMT bars are widely used in the construction of buildings and other concrete structures like. It is most popular when it comes to residential and commercial construction, multi-storied building, bridges, power plants, etc. Make sure you are choosing the best quality TMT bars that provide the perfect combination of strength and flexibility.

Why TMT bars are so popular in the construction industry?

  • => TMT bars are environment-friendly construction materials which can be recycled and reused without any loss in its quality
  • => The best quality of TMT bars can withstand earthquakes and fire.
  • => TMT bars are easy and hassle-free to transport due to its lightweight build.
  • => As TMT bars are flexible, these bars can be used to create any required steel frame.
  • => TMT bars are immensely known for its superior ductility, strength, malleability and weldability which ensure the longevity of the constructed structure.

What are the various grades of TMT bars?

TMT bars divided into various grades – Fe415, Fe500, Fe500D, Fe550 and Fe600. The number denotes yield superiority of the TMT bars. Each grade has different properties and applications and therefore it is important to choose the right grade by knowing its application and usage.

Why Fe 500D and Fe500 TMT bar is the best and most preferred?

In grade, Fe500 and Fe500D contain the lowest amount of Sulphur and Phosphorus that makes these grades highly preferable for all sorts of construction purposes. TMT bars which contain a higher percentage of Sulphur makes it prone to fire and high amount of phosphorus cause fatigue to the bars. The ‘D’ in 500D indicates that it is more ductile than Fe500.


These are some of the most important FAQs about TMT bars. If you are planning to purchase TMT bars, make sure you are purchasing the finest quality from the leading TMT bar manufacturers in India.
