TMT Bar FAQ

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 constructionmaterials used, theconstruction style, and many other factors.
