Why TMT Bars are Most Preferred Over Tor Steel?

What is a TMT Steel Bars?

TMT bars also known as Thermo Mechanically Treated bars predominantly used in the construction industry are high-strength reinforcement bars with a tough outer core and a soft inner core. These bars well known for their corrosion resistance; fire resistance & earthquake resistant properties were introduced to the construction world for the first time in the year 1979. The distinctive manufacturing process of these TMT bars ensures higher flexibility & bendability.

What is a TOR Steel Bars?

TOR Steel bars are High Yielding Strength Deformed steel bars which are cold twisted and deformed after undergoing the heat treatment process. These deformations present on the surface increase the binding properties of concrete, minimize spillage, ensure greater stability & durability. TOR steel bars possess higher tensile strength owing to the uniform placement of deformations along the length the bar.

How is a TMT steel bar different from a TOR steel bar?

In simple words, TMT bar manufacturing process differs vastly from that of TOR steel bars giving each a unique set of characteristics and strengths. TMT bars have a greater advantage over TOR steel owing to their superior strength, corrosion resistant property, ductility, tensile strength and more.

Advantages of TMT bars over TOR Steel bars:

• • TMT bars possess significantly higher tensile strength & lower residual stress as they do not undergo any physical deformation. Thereby making them an apt choice for building durable large-scale & small-scale concrete structures.


• • Additionally, the lack of physical deformation during the manufacturing of TMT bar reduces/nullifies the chances of surface defects which eventually aids in safeguarding structures from the harmful effects of corrosion and ensures longevity of the structure.


• • Consumption of steel is lowered by approximately 20% when TMT steel bars are used over TOR steel for the construction.


• • TMT bars possess a stronger external layer as compared to TOR Steel bars owing to their unique manufacturing process.


• • TMT steel bars contain high thermal resistance and can absorb heat up to 600 degrees Celsius making them a perfect choice for building fire resistant structures.


• • The high elongation property of TMT bars couples along with their high tensile strength and ductility makes structures strong, flexible and earthquake resistant.


• • The unique rib pattern that runs across the entire length of the TMT bars facilitates strong bonding with cement when compared to TOR steel bars.


• • The low-carbon ingredient in TMT bars makes them a viable choice for hassle-free welding works.


• • TMT bars can be used for a wide range of construction works owing to their amazing flexibility and durability.
