Thermo Mechanically Treated (TMT) bar is one of the most popular reinforcement bars used for the construction of houses, multi-storeyed buildings, bridges, flyovers, and civil engineering structures. Sugna TMT is known for its excellent tensile strength, durability, and ductility. TMT steel is the safest option for construction, as they are highly resistant to earthquakes.
In the manufacturing process of Steel TMT bars, Iron scrap is an important raw material. This material (or metal) is melted in an electric furnace and then cast in a casting machine into rectangular shape Billets. Thereafter, they pass through the polishing, and the rolling process is called Hot Rolling Process. The processes of several types above the recrystallization temperature are conducted to get the required size and shape
The hot steel bars undergo a specially designed water cooling system, which is called quenching. This process hardens the outer surface of the bar while the inner core remains a soft and ductile inner core. The variation in the microstructure of the steel bar between the outer and inner core provides huge strength to the TMT bar.
TMT Steel Prices
Sugna TMT steel prices are lower compared to the TMT bars that offer greater structural strength with the same amount of steel. Moreover, this brings down production costs,s and hence, the TMT steel price in the market is much lower. Sugna TMT Bars use one of the best technologies in the manufacturing process with superior raw material, and their affordable prices are another attraction. Therefore, in the construction industry availability of Grades Fe-500 and Fe-600 results in a steel saving of 14 – 19 percent of revenue. This could run into lakhs of rupees for the engine or construction company.
Some of the Applications of TMT bars:
The best part of preferring TMT bars is they offer longevity and robustness to any concrete structure in the construction field.
High rise buildings
Bridges
Flyovers and Dams
Underground structures
Important Features of TMT bars:
Strength:
The High strength TMT bars give much greater strength to the concrete structure.
Corrosion resistance: TMT bars are highly resistant to corrosion. TMT bar shows negligible rusting due to its advanced manufacturing technology. The high thermal stability of the TMT bars is making them safe from fire; hence, TMT bars have longer and safer life than concrete structures.
Flexibility
Sugna TMT bars are incredibly flexible and have a great degree of elasticity. They can be molded into any shape, the most unique feature of TMT bars include higher elongation. This makes it bendable making it safe from natural calamities like earthquakes. TMT Steel bar can elongate up to 50 percent more than its original length. Hence due to its flexibility, TMT bars are used for a wide range of construction purposes.
