TMT STEEL INTRODUCTION
TMT steel Full form is Thermo-Mechanically Treated steel. TMT is high-strength reinforcement steel having an outer core very hard and the inner core is very soft.
TMT MANUFACTURING PROCESS
The manufacturing process of Thermo Mechanical Treatment includes the Below steps:-
- Extraction of iron from its ore.
- Heating, rolling and forming of a reinforced bar.
- Quenching.
- Self-tempering.
- Atmospheric cooling.

What is the Difference between FE 500 & FE 500D TMT Rebar?
TMT Rebar is the backbone for all types of construction in civil engineering.
TMT stands for ‘Thermo Mechanical Treatment’ that is also known as metallurgical process. Its manufacturing process follows IS codes
The construction field mostly uses FE 500 & FE 500D TMT Bars are most used for all civil & retail construction purposes.
Standard Grades of TMT Bars as per IS are:
- Fe 415
- Fe 415D
- Fe 500
- Fe 500D
- Fe 550
- Fe 550D
- Fe 600
In any RCC construction, TMT rebar and Concrete are the two most important components. The life span and safety of these types of structures entirely depends on the properties of the rebar and Concrete. Structural Designers / Engineers should accept TMT Re-bars, only after proper testing and verification of the same irrespective of the name of the manufacturer.
What are the Special Features of TMT Steel Bar?
The best quality TMT Bar comes with the perfect balance of Strength & Flexibility & durability for low carbon content in it.
- TMT Bars undergoes Bend & Re-Bend test because they are relatively high strength steels, and the ribs on the bar surface act as stress concentrators which also improves bonding strength.
- Higher yield strength, Ultimate tensile strength and higher percentage elongation when compared to cold twisted bars (CTD) of the same grade of steel.
- Highly Weldable that makes it usable for all purposes(steel structures building)
- Highly Corrosion Resistant & Seismic Resistant
- Using Fe 500D TMT Rebar can save 2 kg. Per metric ton.
- TMT Bars contain a lesser amount of Sulphur that makes the structures Fire Resistant which can be used in electric towers
- Metallurgical Process called “Thermo Mechanical Treatment” is about dephosphorize the steel in the ladle and desulphurizing the steel in Ladle Refining Furnace and now steel is at par with Primary steel producers.
