February 24th, 2022

It would not be wrong to say that TMT bars are the backbone of modern construction. From homes and commercial spaces to bridges and flyovers, TMT bars give strength to modern structures. This is why when you are building your new home, it is important to carefully choose TMT bars. If you are planning to buy TMT bars for your home, you are bound to have many questions in mind. As the manufacturers of best TMT bar in West Bengal, we answer some of the frequently asked questions on TMT bar:

Question 1: What is a TMT bar?
TMT stands for ‘Thermo Mechanical Treatment’. The TMT steel bars undergo this specialised process. Thermo-mechanical treatment is the simultaneous application to steel that involves heating and cooling. The purpose of the treatment is to refine the micro-structure of steel bars. Steel turns into ferrite pearlite structure. This means the outer core becomes strong and the inside remains soft which allows flexibility.

Question 2: Why TMT bars are needed in house construction?
Though concrete is strong in compression, it is weak in tension. The TMT bars carry the load of the entire structure. Therefore, it is important to go for TMT bars that are known for:

  • Ductility
  • Tensile strength
  • Yield strength
  • Thermal resistance
  • Corrosion resistance


Question 3: Which grade TMT is best for house construction?
TMT Bar manufactured in different grades. The grade refers to the yield strength of TMT Bar. The lowest grade is Fe 415 and it goes up to Fe 600. The usage of each grade depends on the requirement. The Fe- 550D TMT bars are considered a market standard across many construction projects. They are used for residential, commercial and multi-story projects. They are considered ideal for construction in areas with high seismic activity and sudden loads.

Question 4: What are the factors that one should consider when buying TMT bars?
When you are buying TMT bars for your house, make sure you check the following things:

  • Raw materials
  • Manufacturing method
  • Consistent quality along the length of TMT bar
  • Rib pattern
  • Lower impurities
  • Required ductility as per the application
  • Ease of application

Note: One of the best ways to ensure that you are buying quality TMT bars is to check the quality certificate.

Question 5: How are TMT bars manufactured?
There are different manufacturing methods. When you are buying TMT bars for your new home, go for the ones that are made with the latest technologies. Reputed TMT bar brands like ours use the latest technologies such as Thermex. Thermex increases the strength and flexibility of the TMT bars. We use automated CNC machines to give TMT bars a uniform rib pattern. The Uniform rib pattern allows better bonding with cement or RCC.

Question 6: Do TMT bars corrode?
Ordinary TMT bars corrode when exposed to moist air and heavy rainfall. Therefore, it is better to use effective corrosion-resistant TMT bars.
