When choosing the right TMT steel bars for a construction project, you must know their different grades. TMT rebars are used to build the steel framework of beams, slabs, columns, and pillars in a building. Thus, it is important to choose the correct grade while exploring the inventory of the TMT bar suppliers. Infrastructure projects require different kinds of TMT steel bars that suit their requirements. A TMT bar is also categorized into different grades depending on its features, dimensions, compositional strength, and utility in construction.
Grades Available at TMT Bar Suppliers:
If you explore the products of various TMT bar suppliers in the market, you will find that they have multiple grades of TMT rebars. The Bureau of Indian Standards has provided guidelines regarding the different grades of TMT bars in India. All the TMT bar manufacturers in the country follow these guidelines and categorize bars into different grades according to their mechanical properties and material composition. There are four main TMT bar grades in India:
- Fe 415
- Fe 500
- Fe 550
- Fe 600
While selecting bars for their construction projects from the TMT bar suppliers, the builders put a lot of focus on the grade they choose. The effectiveness of each grade of TMT bar depends on the amount of stress they can withstand safely without permanent deformation. For the calculation of this yield stress, the unit used is Newtons per square millimeters.
Applications of Different Grades:
Fe 415 Grade
Fe 415 is the lowest grade of Electrosteel TMT bars available in India. Because of their low yield stress handling capability, they are only used in the construction of small structures. But, they have high ductility and can be used for various construction needs after being bent in the desired shape. These bars are used for small-scale constructions like single-storied houses. They are a cost-effective option that can also be used for building structures in areas prone to earthquakes because of their ductile properties.
Fe 500 Grade
Fe 500 TMT bar grade is the standard option for construction projects available on the market. As they have an overall balanced strength-to-ductility ratio, this grade of Electrosteel TMT bars is widely used in many types of infrastructure projects. Builders and developers use them to create multi-storied, commercial, and residential construction projects. They provide higher tensile strength and ductility properties than Fe 415 and are hence specially used to provide stability to high-rise skyscrapers. These bars also have corrosion resistance.
You can also find a variant known as the Fe 500D TMT bar. It offers greater ductility and is mostly used for the construction of buildings in areas that have high seismic activity. The high flexibility allows it to absorb earthquake shocks and stress from extra load.
Fe 550 Grade
Fe 550 has a higher tensile strength than lower graded TMT bars. While it lacks some ductility, these bars are still used for the construction of large infrastructure and industrial projects like power plants, warehouses, etc. Fe 550 TMT bar grade can provide support to building structures that need high load-bearing capacity. When you explore the products of the top TMT bar manufacturers, you can check out the TMT bar prices today in Ranchi of this grade.
Fe 600 Grade
It is the highest graded TMT bar available in India. Fe 600 has great strength but it also has the lowest ductility among other TMT bar grades. This is why this grade of steel bars is only used for infrastructure projects with heavy-duty requirements. Because of their corrosion resistance, these bars are also used for construction in coastal, marine, or underground environments. You can use Fe 600 TMT bar grade for the construction of marine facilities, metros, highways, dams, bridges, docks, etc. Explore the TMT bar prices today in Ranchi of Fe 600 grade before procuring them for your construction project.
Builders and developer firms use different grades of TMT bars to construct their various industrial, commercial, and residential projects. The chosen option should provide the necessary durability and strength that can contribute to the longevity of buildings being made. By using the application details of the various TMT bar grades, you can select a suitable one for your construction project.
