TMT saria or TMT bars are a popular element in the construction world. TMT saria is used to build the structure of all constructions for strength, durability, and safety. These specially treated bars have become indispensable for small, as well as huge, constructions like dams and bridges across the globe. This article will guide you through everything you need to know about TMT saria.
TMT saria or bar is a steel bar that has undergone the Thermo Mechanical Treatment process. The basic material of TMT saria is the superior quality steel billets, which are made by combining iron ore, coal, and limestone. The basic material goes through a specialized process of hot rolling, rapid cooling, and self-tempering to be transformed into strong, ductile, and corrosion-resistant steel bars. Due to better ductility and strength, it can resist extreme pressure and earthquakes.
Thermo mechanical treatment has several steps, and they vary slightly for producing different grades of TMT saria. The basic treatment has the following three steps.
In the first step, the raw steel billets are put in a heated rolling mill at a temperature between 1100 and 1200 degrees Celsius. The rolling mill or furnace distributes and maintains the same temperature throughout the billets. This initial process breaks down the grains, makes the steel more flexible, and gives the steel the desired shape and size.
Just after hot rolling, the steel is put through rapid cooling under a cold water spray. This process is also called quenching. This rapid cooling makes the outer surface or wall of the steel hard and solid, while the inner core remains soft.
In this step, the bars are left for a certain period. This period allows the inner core to transfer the remaining heat to the surface. This process releases excess stress in the bars, making them more resilient, strong, and ductile.
The special process gives TMT saria some unique features that make them indispensable for strong constructions.
The controlled cooling process and self-tempering process make the outer layer of the TMT saria tough. This tough outer layer has exceptional tensile strength, which helps TMT bars to withstand extreme pressure and load. This is why the TMT bars are used in making the concrete structure.
During rapid cooling and the self-tempering process core area of the TMT saria remains soft for long, which helps attain superior ductility. That means the TMT saria can go through significant elongation or deformation before breaking. This feature makes it ideal for withstanding earthquakes and other external forces.
Corrosion is a permanent problem in construction, especially in areas with extreme moisture. Corrosion can undermine any construction over time. Due to the corrosion-resistance feature of TMT saria, it is used in the core structure of construction.
The weldability of TMT saria is excellent. It can be welded or joined with other steel components. High weldability helps achieve seamless integration without losing the strength and ductility of the TMT bars. Besides this, high bendability helps give it any shape required for construction.
Due to the treatment it undergoes, TMT saria is capable of resisting extreme heat and fire. This feature ensures the structural stability and resistance to structural deformation of the building in case of fire breakouts.
There are several grades of TMT saria available with different load-bearing capacity and ductility levels. Fe 415, Fe 500, Fe 550, and Fe 600 are the names of the grades. Here, the number denotes the minimum yield strength of the bars.
TMT saria is an essential product in the contemporary construction industry, having a higher strength, better ductility and superior durability. It also is not a weak building material like concrete whereas while fabrication, rapid cooling, and self-tempering are ideal for seismic actuated emergencies, heat stress, and corrosion. These features make tmt bars the preferred resource for all infrastructure purposes, be it residential or large projects, such as flyovers, highways and dams.
And, the selection of the best-grade TMT saria, like Fe 415 or Comparatively high weldability and bendability, TMT bars make construction work easy and safe while maintaining resistant to building pressure.
