What is TMT Bar
TMT bar is known as Thermo-Mechanically Treated bars. The Manufacturing process of TMT bars are different from normal bars. These are formed by special process, In which first of all the Raw Material is heated in very high temperature and particular shape is to be given that, and after the shape and structure, that heated bar directly cool downed with the help of water. This Immediate cooling process makes this Bar strong through outside and Flexible through inside. That’s why these TMT bars are easily Bent but does not breakdown easily. These bars are totally different from Traditional Steel bars.
Why Quality TMT Bars Matter in Construction
While choosing anything the first thing that we have to look about is the quality of the product because quality matter in everything. So when we are looking for the TMT bar, the first we have to look about the quality of the TMT bar. In the Construction the most important thing that provide Strength, durability and Flexibility to the structure is the TMT Bar that we used. A good quality TMT bar increases the life of any building. The Important role of TMT bar in building is to handle the environmental stress like Temperature change, heavy rainfalls and earthquake

- Carbon:- The role of the Carbon in TMT bar is to Increase the strength and Hardness of the Bar. Its quantity Must be around 0.25%
- Manganese:- This helps in Improving toughness of the bar. Its amount should be around 0.5 to 1.0%
- Phosphorus:- Phosphorus helps in reducing ductility and Toughness of the TMT, it should be less then 0.05%
- Sulphur:- Sulphur is a unwanted impurity and it is Controllable element in TMT bar. Content of this element should be less than 0.040%
- Silicon:- Silicon increases strength and toughness of TMT, Its Quantity must be around 0.1% to 0.4%
- Copper, Nickle, Chromium:- These are the other useful element in TMT bars, helps in preventing rust and corrosion. Content usually around 0.1% to 0.4%
