TMT Bars

Thermo-Mechanically Treated bars, or TMT bars, are high-strength reinforcement bars with a strong outer core and a soft inner core. Passing steel wires through a rolling mill stand is the initial stage in the production process. These rolled steel wires are then sent through the Tempcore water cooling system once again.The water pressure is optimised while the wires are going through the water cooling system. The steel bar’s outer layer is toughened by the quick quenching and severe temperature shift, making it very tough and durable. The TMT bars are then exposed to ambient cooling once this procedure is completed.This is done to bring the temperature differential between the soft inner core and the tough outer core closer to zero. As the TMT bar cools, it gradually transforms into a ferrite-pearlite mass. Because the inner core is soft, the TMT bar has a high tensile strength and elongation point.TMT bars have a design that is unique to them and provides them excellent ductility. This bar is also corrosion-resistant and weldable because to its unique production method and lack of cold stress.

High-quality SRMB TMT bars are made using the same manufacturing method. TMT bars have a higher tensile strength as a result of this. Higher elongation is one of the most essential properties of the SRMB TMT bar. This increases the bend/re-bend characteristics of TMT bars, making them more resistant to natural disasters like earthquakes. The Thermal stability of SRMB TMT bars is high which makes them safe from any fire accidents. The special ribbed design of the SRMB TMT bars form a stronger bond with the concrete or cement, thus, provides additional support and strength to the building structure and improves their longevity and durability. The high tensile strength and flexibility make SRMB TMT bars the ultimate choice for earthquake-prone zones. SRMB TMT bars have greater shock-absorbing capacity when compared to other TMT bars. The strength of the structure and the prevention of the collapse of the building during an earthquake are both ensured. Compared to ordinary steel bars, the same quantity of TMT bars can provide 20% additional strength to the structure. Other SRMB products include AZAR Bars (Zinga coated TMT bars), De-formed TMT bars, and De-formed corrosion resistant TMT bars.

Types of TMT bars

There are different types of grades available in TMT steel bars, where grade refers to the amount of stress used to deform the bar. Quality is an important factor for any product and we provide you with better quality according to your requirements. These are the types of TMT steel bars available with us.

Fe-500 grade TMT Steel bars: Fe stands for iron chemically. This grade was replaced by the Fe-415 grade for its excellent bending properties and resistance to dynamic loads. In buildings, bridges and other concrete structures, it is used in RCC constructions.

Here are a few different sizes of TMT steel bars and their uses:

There are different diameters of TMT steel bars, such as 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 36mm, and some well-known TMT manufacturers are now planning to manufacture in larger diameters.

8mm-10mm size bars are used in Slabs and Stair ups, which serve as a load bearing component of slab houses.

12mm-25mm size bars are used in Beams & Columns, making them stronger against external forces.

32mm-36mm size bars are used in the construction of very complex projects such as dams and bridges.

The sizes are also determined by the designs. The size of the containers varies depending on the specifications of the project.
