Thermo-Mechanically treated bars or TMT Steel bars are used in a wider extent for different construction projects. These bars are prepared through Thermo-mechanical processing that combines the mechanical process with thermal process at various rates into a single process.

Types of TMT Steel
The various types of TMT Steel are actually identified by their grades. TMT bars have been classified as Fe 415, Fe 500, Fe 550, Fe 600. Where Fe represents the symbol of iron, and the number following it represents the yield strength of steel.
- Fe – 415: As Fe-415 is having higher uniform elongation, it is used in RCC constructions in corrosion-prone area and also in an earthquake-prone zone
- Fe – 500: Due to its high corrosion resistance, excellent bending ability and resistance towards dynamic loading, Fe – 500 is widely used in RCC constructions in buildings, bridges and other concrete structures
- Fe – 550: Fe-550 has its properties similar to Fe – 500, and differs only in terms of yield and tensile strength. It is widely used in RCC construction exposed to coastal, marine or underground environment
- Fe – 600: As it provides better toughness and has more yield and tensile strength compared to other TMT Steel grades, it is used for large RCC construction purposes

How to identify best TMT Steel
Different criteria which has to be kept in mind while choosing a TMT steel bars are as follows:
- Grade of the TMT Bars: The bars are available in 4 different grades- Fe-415, Fe-500, Fe-550, and Fe-600. The higher is the grade higher is the strength of the bar. Higher grade TMT bars generally used in the core of a building such as in the floors and roofs. Lower-grade bars can be used in construction balcony railings and decorative structures.
- Flexibility of the bars: Bars should be flexible enough to withstand stress for long ages. Hence we should choose high-quality TMT bars which are having more flexibility so that the rods do not develop cracks even when bent at 90 degrees or more.
- Maximum extent of elongation of bars: We need to find how far the bars can be elongated which indicates how ductile the bars are. The higher is this number, the more you will be able to save on construction.
- Corrosion resistance of the bars: TMT Steel rods used to come in contact with lots of moisture during construction. So, resistance towards corrosion is a must, otherwise, they will not last long.
Weight of TMT bars as per size
TMT SIZE | TMT RODS PER BUNDLE | TMT WEIGHT PER BUNDLE |
8mm(1 bundle) | 10 | 47 kg |
10mm(1 bundle) | 7 | 53 kg |
12mm(1 bundle) | 5 | 53.4 kg |
16mm(1 bundle) | 3 | 56.88 kg |
20mm(1 bundle) | 2 | 59.2 kg |
25mm(1bundle) | 1 | 46.2 kg |
32mm(1bundle) | 1 | 75.72 kg |
Different uses of TMT bars as per different sizes
TMT Steel bars come in different diameters like 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 36mm.
- 8mm-10mm size TMT bars are used in Slabs and Stair ups, that serves as a load-bearing member in slab homes
- 12mm-25mm size TMT bars are used in Beams & Columns, to enable them to withstand external loads
- 32mm-36mm size TMT bars are used in very complex construction projects like dams and bridges
SUMMARY
TMT Steel Bars are high in demand in the market due to its low-cost reinforcement bars in construction projects. Thermo-mechanically treated (TMT) steel bars are highly preferred compared to torsional bars, as these have high strength and ductility. This is one of the key factors because of which TMT Steel bars is now boosting its demand globally in the steel bars market.
