TMT Bars And Their Influence
TMT bars have become the backbone of every civil construction out there, they can give structures shapes, strength, and they can be moulded to make slabs, beams and columns as well.
As the expectations and demands of the common man rise with respect to make real estate structures. The need for high-quality materials for building structures has also gone, and this is one of the reasons why TMT bars have taken the centre stage in the construction field. TMT bars come in different grades so as to cater to different needs. These TMT bars have the approval of the Bureau of Indian Standards for building and construction projects. While Fe 415 is the popular choice among homeowners, Fe 500 and Fe 500D have carved out a market for themselves. In the blog, we will take a look Fe 500 and Fe 500D, just like Fe 415 they too are popular with a section of architects and engineers.
The TMT in TMT Bars stand for Thermo-Mechanically Treated, it is a process of rapidly cooling down bars in the molten state. This cooling down process is either done spraying water at regular intervals. This regular interval will further define the characteristics of the bars. This interval of quenching of bars will give rise to different grades of TMT bars in fact. The goal here is to have a solid and hard outer surface with a pliable inner core. This outer shell is coated with a protective film, making them resistant to corrosion and rust, making them apt for constructing sensitive structures such as high rise residential buildings and bridges in humid areas. TMT bars and different Steel Grades.
TMT bars of the same grade usually have more than one type, while it is uncommon to hear about Fe 415D or Fe 415S. One must surely be heard of Fe 500 and Fe 500D, here Fe stands for iron, 500 stands for the tensile strength and D stands for ductility. Other than the names they also have a different chemical composition as well. When talking about carbon content Fe 415 has a maximum per cent 0.30 carbon while Fe 415 D and Fe415 S has a maximum carbon per cent of 0.25.
Concrete is the heart and soul of any construction project, they can moulded into almost shape and can withstand anything weather and climate around the world. But, what the concrete lacks is the strength, ductility and a low tensile strength. This is where TMT bars come to save the day, a mix of concrete and TMT bars can help engineers to build structures like never before in the history of mankind.
