TMT bars (Thermo-Mechanically Treated bars) are steel reinforcement bars that are used in construction to provide strength and stability to concrete structures such as buildings, bridges, and roads. TMT bars are made by a process that involves heating the bars to a high temperature and then rapidly cooling them, which changes the microstructure of the steel and improves its properties.
The TMT process enhances the strength, ductility, and corrosion resistance of the steel, making it more suitable for use in construction. TMT bars are also more resistant to earthquakes, fire, and other natural disasters than other types of reinforcement bars. TMT bars are available in various sizes and grades, which are suitable for different types of construction projects.
TMT bars are known for its high strength, durability, ductility, bendability, weldability and corrosion resistance. They are widely used in construction of high-rise buildings, bridges, flyovers, and other structures.
It is important to note that TMT bars should be used as per the Indian Standards (IS: 1786-2008) and the quality of TMT bars should be certified by Bureau of Indian Standards (BIS) before use in any construction.
