Contractors’ Trusted Choices of TMT Steel Bars in India for Construction
TMT Bars, also known as Thermo-Mechanically Treated Bars, play a main role in construction projects by providing the necessary tensile strength and durability to withstand various forces. Whether you’re a contractor or an individual looking to build your dream home, this blog will provide you with valuable information on the best TMT bars in India.
TMT means “Thermo-Mechanically Treated ” these bars contain a solid exterior and a soft interior. TMT bars are used in many construction industry sectors, such as
- Residential/commercial buildings
- Bridges
- Industrial constructions
- Concrete reinforcement
The main advantage of TMT, which outperforms its alternatives, steel bars, is that TMT bars are immune from corrosion damage.
Here’s the list of the Best TMT Bars in India.
Types of TMT Bars in India
In construction projects in India, two primary types of TMT bars are used:
Low-Ductility Bars
Low-ductility TMT steel bars are known for their high strength but lower elongation properties,
making them more brittle compared to high-ductility TMT bars. They can withstand higher stress than high-ductility bars, but they have a lower resistance to deformation.
Manufacturers can produce low-ductility TMT bars by using a higher percentage of carbon and other alloys in the manufacturing process to enhance their strength, making them more cost-effective than high-ductility TMT bars.
However, low-ductility TMT bars have a higher risk of sudden failure in the event of an earthquake or other severe environmental stresses. Therefore, engineers and contractors must carefully evaluate the specific requirements of a project before selecting the type of best TMT bar to use, ensuring the safety and longevity of the structure post checking with all TMT bars manufacturers in India.
High-Ductility Bars
High-ductility TMT Steel bars , also known as earthquake-resistant bars, possess superior elongation and ductility properties compared to low-ductility TMT bars.
These bars can withstand higher deformation and stress due to seismic activity, making them an excellent choice for structures located in earthquake-prone areas. Manufacturers enhance the ductility of these bars by adding certain elements, such as copper, during the manufacturing process. The ductility of these bars helps absorb the energy generated during an earthquake or other environmental stress, preventing sudden failure and collapse of the structure.
High-ductility TMT bars are typically used in critical infrastructure such as
- Hospitals
- Schools
- High-rise buildings
where safety is of utmost importance.
Grades of TMT Steel Bars & Its Applications
In India, TMT bars are available in various grades that determine their strength, durability, and ductility.
The Bureau of Indian Standards (BIS) regulates the quality and standards of TMT bars in India and defines these grades. These different grades indicate the strength & rigidity factor of the steel bar. The numbers indicate the force that must be applied to deform or modify the steel bars for various purposes. For example, ARS 550D, with a yield strength of 550 MPa, is the strongest grade and the best TMT bar available in South India and is primarily used in heavy construction projects such as dams, bridges, and high-rise buildings. ARS is a leading TMT Bars manufacturers in India . Additionally, higher grades of TMT bars like Fe-600 and Fe-650 are used in special construction projects requiring high strength and durability and will be available under the ARS brand soon.
