Best TMT Bar Manufacturer and Supplier in India

The infrastructure sector is growing at a rapid pace in India contributing to a major part of the economy. The infrastructure sector comes hand in hand with the construction and real estate industry, where TMT bars are widely used in the process of reinforcing several concrete structures including houses, high-rise residential/commercial buildings, office/industrial structures, roads, highways, bridges, flyovers, dams, thermal and hydro power plants, oil refineries and so on. Thanks to their excellent weldability, superior bendability with corrosion, fire and earthquake resistance qualities, QST bars or TMT Rod are witnessing a significant surge in demand paving a new era of advanced growth in the entire steel market and Construction Steel industry. Elegant Steel boasts of being primary quality steel produced at our integrated steel plants where the fine quality of raw iron ore is brought under strict monitoring while manufacturing of TMT bars, processed through various state-of-the-art technologies to convert iron into quality crude steel. Stringent quality checks in every step of the production process along with superior quenching and tempering system contribute to produce world-class QST bars. Thus, Elegant QST bars exhibit consistent superior strength and high ductility/flexibility, which is required to ensure superior and safe structures.

TMT Bar Application Areas

Different projects call for different types of TMT bars depending on the compositional strength, dimensions and features. Available in multiple variations, Elegant QST bars are used by reputed construction and developer firms across residential, commercial, industrial as well as infrastructure sectors. Given their ability to provide optimum strength, safety and durability to the structure, TMT bars are used for critical civil construction purposes such as power plants, dams, long-span bridges & flyovers, roads & highways, underground structures & underwater or marine structures, oil refineries and so on which are produced by TMT bar manufacturers in Kolkata. Apart from these, QST bars are also used in high-rise buildings, malls, schools, airports, hospitals and other large structures.

QST bars are extremely important and often used in earthquake-prone areas since their high bendability/elongation property can protect the structure from being uprooted. Elegant TMT bars are the perfect choice for corrosion-prone areas as the tough outer layer prevents rust, which is often responsible for causing cracks in the structure. Be it a residential building, hospital or any other construction – no structure can skip the risk of being exposed to fire. Being fire-resistant with high heat-withstanding capacity with Reinforcement Steel, Elegant QST bars can be used for all types of construction purposes.

Why should you choose the Elegant QST Bar in India?

  • Elegant QST bars give up to 20% stronger concrete structure compared to conventional bars using the lesser quantity of steel made by steel products manufacturers in India.
  • The high bend ability of Elegant QST bars provides better resistance to any structure during natural calamities.
  • Elegant TMT steel manufacturers in India makes QST bars which comes with uniform ribs that provide an unshakable bond with the concrete mix.
  • Elegant QST bars are extremely shock-resistant due to their high elongation capability. This feature makes them the ideal choice for significant construction activities in seismic zones.
  • Elegant QST bars are known for their corrosion-resisting capability. The tougher outer layer of the TMT bars made with the world-class QST system prevents the bars from getting oxidized from TMT bar company in Kolkata. Thus keep the bond with the concrete intact and resist harm to the structure.
  • High heat-withstanding capacity due to their unique self-tempering process makes the QST bars fire-resistant.
  • Elegant QST bars can ensure up to 14% savings in steel usage through their uniform and controlled sectional weight and also higher yield and tensile strength than grade 550D.

Manufacturing Process

QST or TMT stands for Quenched and Self-Tempered steel rebars fabricated by a quick cooling process called quenching and self-reheating of hot-rolled steel bars. The manufacturing process of Elegant QST bars usually involves 3 essential steps –

  • Quenching
  • Self-tempering
  • Atmospheric cooling

The Process

  1. The raw materials such as iron ore, coal, dolomite etc. are piled, recovered and mixed in required proportion and converted into metallic iron.
  2. The primary construction steel making process begins with the conversion of metallic iron to crude steel through electric heating and refining and after refined steel is brought to the continuous casting machine to solidify into rectangular cuboid called billets/blooms.
  3. Hot billets are rolled through thermomechanical treatment in fully automatic rolling mill, processed through quenching and self-tempering system and finally, rested for atmospheric cooling to produce the world class quality QST bars.
  4. The stringent quality checks are carried out through in line production and final products are tested for chemical, mechanical and physical properties. Batch identification is attached to each lot.

From procurement of the raw material to the manufacturing of TMT bars and dispatch of the final product, the entire process takes place in our integrated steel plant, which allows us to produce the best quality TMT bars in India.
