TMT steel Bars in India: It’s types, features and applications?
Thermally mechanically treated (TMT) bars which are incredibly needed in a magnitude of construction projects, such as columns, beams, complete buildings, etc. TMT bars are well-known preferred for constructing resilient structures—be it sturdy flyovers, tall buildings, or massive dams. So, let's drive deep and know about the different types of TMT Steel bars, but before that, let's know what exactly TMT Steel bars are and which are best TMT bars for home construction.”
Well, what exactly are TMT Steel bars?
TMT Steel bars are very high-strength reinforcement bars which can stand protection against natural disasters and earthquakes. They are tough on the outside and have a very soft inner core, which makes them best TMT bars for house construction.
It offers impeccable properties such as
- Resistance to rust
- Low carbon content
- Strong material strength
- Great finish
- Outstanding performance
Types of TMT Steel bars
TMT Steel bars come with different features, dimensions, sizes and strengths in accordance with a project and fall under the category of Fe415, Fe500, Fe550, Fe600
1. FE 415 grade
FE 415 is very affordable in comparison with other TMT grade bars. It is mostly useful for small projects such as residential homes and small civil structures.
Features
- Yield strength of 415 N/sq.mm.
- The least amount of force needed for deforming its shape.
- Unique property that withholds the places where heavy shaking or earthquakes are common.
- Incredibly provides resistance towards corrosion and rust.
2. FE 500 grade
TMT bars are incredibly preferred choice for industrial projects with Fe 500S and Fe 500D, known for their structural strength and ductility.
Features
- Great for RCC structures even in the earthquake-prone areas
- Mainly considered for bridges, and high-rise buildings.
- Corrosion-resistant and provides very high weight-bearing capacity.
- Great tensile strength along with high ductility.
3. FE 550 grade
It is mainly useful for building large-scale projects due to its high tensile strength.
Features
- Used in industrial applications.
- It can be transformed into high-grade alloy Steel when combined with Phosphorus, sulfur, and carbon.
- Used to build heavy structures such as bridges.
- Coastal and marine kind of projects.
4. FE 600 grade
Considered the strongest Steel grade and useful for constructing heavy structural projects.
Features
- Heavy-duty projects such as high-rise towers, metro rails, highways, etc.
- Can support heavy load projects
- Height tensile strength, durable, and corrosion resistant.
Difference between various TMT bar grades
| Parameter | FE 415 | FE 500 | FE 550 | FE 600 |
|---|---|---|---|---|
| Cost | Most Affordable | More as compared to FE 415 | More than FE 500 | Most expensive |
| Elongation | 14.5 | 12 | 10 | 10 |
| Tensile strength | 485 | 545 | 585 | 660 |
| Properties | Flexible and most affordable | Useful in industrial use | Have balanced ductility and strength | High strength and ductility |
| Applications | Small-scale and residential | Commercial buildings and bridges | Industrial applications | Critical structures, top-notch performance projects |
Types of TMT Steel bars
There is no doubt that the construction industry is expanding at a rapid rate, and requirements of TMT bars has also increased as it is used for overall constructions such as building shopping malls, residential schools, commercial projects, such as dams, bridges, and buildings. Depending upon the need, The Real Infra Team uses the right kind of TMT bars to make your project super-strong, durable with high tensile strength.
