TMT Bars
TMT (Thermo - Mechanically Treated) Bars or TMT Sariya are reinforced bars having a tough outer core and a soft inner core used in all types of general and heavy construction including building, infrastructural projects, housing projects, dams, bridges & houses.
TMT bars consider as best bars for all weather conditions including torrential rain, earthquake to toughen your construction and also help the building from catching fire and bond perfectly with cement, and is resilient to any kind of load.
TMT bars are a quality product for strong and durable construction, it comprises several grades including FE-500, FE-500D, FE-550.
Why TMT Bars:
TMT Sariya or bars is the best choice of all types of construction because of the following characteristics.
Earthquake-resistant:
Earthquakes are becoming common in some parts of India. An earthquake is different than another disaster like heavy wind, which forces or attack all the structure. earthquake, earth moves, and the structure foundation directly affected to its. The structure or construction that builds from the steel TMT bar is good earthquake resistance. steel TMT bars have a tough outer core and a soft inner core that provide construction flexibility and strength. TMT bars have elongation properties which help to absorb earthquakes
Ductile and Strength:
TMT reinforcing bar has an inner and outer ring, the soft inner layer gives the rebar a bendability and provides better ductility. In the TMT bars manufacturing processelements like sulfur and phosphorous are reduced and silicon & manganese are added which makes the rebar even more ductile.Steel is an alloy of iron and carbon, hence steel TMT bar comprise ductility and flexibility
High Thermal Resistance:
How much the material can resist the flow of heat, defined the thermal resistance property of that material, nowadays engineer consider the high thermal resistance bars to create the foundation of the construction, that has a hard surface outside with softcore inside which comes through 3 steps manufacturing process involves quenching, Self Tempering, Atmospheric cooling. High Thermal Resistance properties increase the life span of the construction hence economic savings to the projects.

TMT bars or Thermo-Mechanically Treated bars are high-strength reinforcement bars made with having a tough outer core and a soft inner core. TMT bars are generally used material in construction for enhanced protection against earthquakes& other natural disasters. TMT bars consider as best bars for all weather conditions including torrential rain, earthquake to toughen your construction and also help the building from catching fire and bond perfectly with cement, and is resilient to any kind of load.
The high strength of the TMT bars makes them an ideal material to be used with concrete for providing strength to the buildings. They are used in construction to add robustness and durability to the structure.TMT bars are widely used in general purpose concrete reinforcement structures, bridges and flyovers, dams, thermal and hydel power plants, industrial structures, high-rise buildings, underground platforms in metro railway and rapid transport systems.
The price range of various TMT bars ranges as per their grades. For more details on price kindlyvisit our website or contact us.
TMT steel bars are available in multiple grade variations, being used by construction and infrastructure firms for their projects. Choosing the right grade will help to preserve the structure during the events of an earthquake.For the TMT Steel category, the four primary grades of steel accessible in India are; Fe 415, Fe 500, Fe 550D, and Fe 600 where the number decides the yield quality of the steel product.
The full form of TMT bar/Rebar is Thermo Mechanically Treated bars.
Here are few tips to keep in mind while you evaluate your purchase for TMT bars
- When bent, bar should bend smoothly.
- Transverse Ribs or Lugs of the bar should be sharp. So that it bonds strongly with the cement.
- Before purchasing bar, one should check its price in the newspapers.
- Comparable weight of bar per meter should be according to ISI standards.
- Cross check when you weight the bar.
- bar should be of any ISI & ISO certified.
- Every meter length of bar should bear company's stamp.
- Every bundle should carry company's seal on it.
The first step of the manufacturing of TMT bars involves passing the steel wires through a rolling mill stand. Then the rolled steel wires are again passed through the tempcore water cooling system. While passing the wires through the cooling water system, the water pressure is optimized. The sudden quenching and drastic temperature change toughen the steel bar's outer layer, making it extremely durable. Once this process is completed, the TMT bars are subject to atmospheric cooling. This is done to equalize the temperature difference between the soft inner core and the tough exterior. Once the TMT bar cools down, it slowly turns into a ferrite-pearlite mass. The inner core remains soft, giving the TMT bar great tensile strength and elongation point. This design is unique to the TMT bars and gives superior ductility to the bars. This unique manufacturing technique and the absence of cold stress make this bar corrosion-resistant and boost its weldability...
CRS in TMT bars stands for Corrosion-resistant bars. It helps in reducing the rate of corrosion from the time of Construction and thus enhances the life span of the structure.CRS TMT bars are produced with an addition of corrosion resistance elements such as copper, chromium, and phosphorus. Thus, are considered to be more advanced and have a longer life than ordinary TMT bars. The high corrosion resistant feature makes them an ideal choice for projects near coastal areas and structures such as bridges and dams.
The features of the TMT bars are:
- Enhanced strength combined with high ductility
- High thermal Resistance
- Better Malleability
- Excellent weldability without loss of strength at welded joints
- Cost-efficient
- Earthquake Resistant
TMT steel bars are known to have a longer life span than regular bars due to their anti-corrosion and anti-rusting Properties. The exact life span of the TMT steel depends on the quality of the construction materials used, the construction style, and many other factors.
