This financial year has given a boom to the global iron and steel market and the demands for the Thermo Mechanically Treated bars are all time high. The FY 2015-2016 has been extremely great for the iron and steel industry. TMT bars have been a blessing to the construction industry and a major cause behind its sprawling growth and soaring economy. The construction industry doesn’t seem to be complete without the use of TMT bars. From the bridges and flyovers to buildings and power plants – TMT bars are used in a broad spectrum.

What are TMT Bars?

The TMT bars are in fact Thermo-Mechanically Treated bars. Such bars are manufactured by combining the heat treatment and work hardening process. Such bars are one of the strongest steel products and have a great resistance to corrosion. The TMT bars majorly comprises of the chemicals like Carbon, Sulphur, Manganese and Phosphorus. In general, there are different grades of TMT steel that decide its strength. The primary grades include Fe 415, Fe 500, Fe 550 and Fe 600. All these TMT bar grades have different yield strength, tensile strength, elongation and chemical ...
... properties. The high strength TMT bars are in a huge demand as per the present scenario. The view of a construction site is pretty common nowadays and every site includes the use of TMT bars.

Manufacturing of TMT Bars

Manufacturing of TMT bars is a hi-tech and profitable business. The process needs cutting-edge equipment. It is done on medium or large scale. TMT bars are one of the strongest forms of the modern steel. The manufacturing of TMT bars is done keeping few vital factors in mind like bendability, ductility, strength and weldability. In the first place, the raw steel wires are passed through a rolling mill and then through specially designed water cooling system. The pressure of the water is optimized while passing through the water cooling system. The outer layer of the steel wires becomes tough and enduring experiencing the abrupt alteration in the temperature. After this, the steel bar or TMT bar is kept outside for atmospheric cooling. This is done to balance the outer layer and inner core temperatures. Once the temperature gradient is created in the bars, they attain a great tensile strength due to the soft inner core.

How is TMT Bar Manufacturing Profitable?

The evolution in the quality and strength of TMT bars have made them immensely popular in the global construction industry. A customer avails a range of benefits paying a reasonable price for the TMT bars. The key benefits of TMT bars include earthquake resistance, resistance from corrosion, great bonding strength, great thermal resistance, high tensile strength, toughness, sustainability and more. Apart from the huge productivity of steel, the iron and steel industry receives a great support from the government in the nations like India, China, US and Japan. The construction industry is already flourishing and without TMT bars, it’s tough to imagine the enduring and reinforced construction.
