TMT rebars (Thermo-Mechanically Treated Reinforcing bars) are a type of steel reinforcement bars that are used in construction to provide strength and stability to concrete structures such as buildings, bridges, and roads. TMT rebars 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.
TMT rebars are used as reinforcement bars in reinforced cement concrete (RCC) structures. They are used to provide additional strength and support to the concrete and help to distribute the load of the structure evenly. TMT rebars are made from high-quality steel and are available in various sizes and grades, which are suitable for different types of construction projects.
TMT rebars 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.
The TMT process enhances the strength, ductility, and corrosion resistance of the steel, making it more suitable for use in construction. TMT rebars are also more resistant to earthquakes, fire, and other natural disasters than other types of reinforcement bars.
It is important to note that TMT rebars 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.
