When making your dream home, you will only want to choose the right materials. One of the most essential raw materials is TMT bars. These bars are manufactured with a unique process known as thermomechanical treatment. This gives the bars their soft core and hard exterior. It ultimately leads to increased strength, elongation, corrosion & earthquake resistance, and many more unique properties. In this blog, you will get to know about different grades of TMT bars and know which one is ideal for building your dream home.
Significance of Grades On TMT bars
The grades of a TMT bar indicate how much force is required to deform them. The higher the grade, the stronger the bar. The ‘FE’ before the grade numbers signify the iron that is used in their manufacturing. The number that follows ‘FE’ indicates its ductility and how much stress it can endure. The quality of these bars can be checked manually with the help of different tests, like bend test, chemical test, manual test, etc. The ratio of components like carbon, sulfur, and phosphorus used in the manufacturing process defines the grades and qualities of TMT Bars.
Different Grades Of TMT Bars
FE 415 TMT Bars
This is the most economical grade of TMT bars. FE 415 TMT bars are suitable for small-scale construction. FE 415 TMT bars are mostly used for reinforced cement concrete (RCC) projects. They have a higher prolongation of almost 14%, making them the preferred choice for projects for areas with low-urban development.
FE 500 TMT Bars
FE 500 TMT bars have a high level of strength, with a yield strength of 500 N/mm2. They can bear seismic and dynamic loading effectively, which makes them suitable for construction in earthquake zones 3, 4, and 5. This grade can be used in any type of construction and is 20% stronger than the previous grade.
FE 550 TMT Bars
This is one of the strongest TMT bars that is used in construction. FE 550 TMT bars are often used for the construction of high-rise buildings and residential complexes. They are extremely different from the previous grades, even FE 500. FE 550 has a minimum yield strength of 550 N/mm2 and a tensile strength of 585 N/mm. It also saves 10% on steel consumption compared to traditional FE500-grade rebars.
FE 600 TMT Bars
Stronger than the other grades, FE 600 TMT bars have the highest tensile strength of all grades of bars. Maan Shakti, the leading TMT bar producer, manufactures this grade, which is made from the best materials. FE 600 TMT bars have the maximum strength and ductility among all bars. They are even used for civil construction and maritime projects and bend easily. The quality of the raw materials used in this grade is high, and the process is closely monitored.
Ideal Grades Of TMT Bars For Residential Construction
The higher the grade, the stronger the construction. Lower grades like FE 415 are used for small-scale construction projects. They are ideal for minor load installations in areas with little to no seismic activity, as the bars are flexible and cost-effective. FE 500 and FE 550 TMT bars are ideal for residential buildings and multi-storey commercial buildings. They are mostly used for business complexes and private homes. They can endure earthquake tremors and can be used in zones 2,3 and 4. FE 600 TMT bars are mostly used for civil projects. They are best for bridges, dams, and other projects that need to endure daily stress.
How To Choose The TMT Bar Grade?
Your choice of TMT bar depends on your needs. If you are in a safe area and are constructing a small home, FE 415 may be suitable for you. However, FE 500 and 550 are the most frequently chosen TMT bars. They can increase the longevity of your home and eliminate the need for regular repair. With proper maintenance, your home will stand the test of time and also keep the residents safe.
The Bottom Line
Choosing the right grade of TMT bar is essential not only for the longevity of your home but for your pocket, too. Lower grades require frequent maintenance, which will ultimately increase the cost of construction. They degrade quickly and weaken the structure. Your choice should be well-thought-out and based on your needs. Do not rush while making your decision, and choose your TMT bars wisely.
