Steel is considered to be one of the important construction material for building any kind of structures. Its uniqueness lies in the fact that, when it is combined with concrete it not only protect wear and tear but also protect structures from natural calamity like earthquake.
There are so many different types in Steel bars which are used for various purposes. Generally, the type of steel bars varies depending upon the geographical. Earlier TOR steel was being used vastly, later on TMT Bars gradually captured the market.
TMT vs TOR Steel
Through this blog lets understand the difference between TMT vs TOR Steel.
TOR came into existence after the brand name ‘Toristeg Steel Corporation’ of Luxembourg. Because of high adherence TOR was one of the best grades of steel used in the concrete reinforcements. But due to more tensile stress and high elasticity value which intern created residual stress and the end of TOR steel corrosion-prone.
TMT which stands for Thermo Mechanically Treated Bar, also called as Reinforcing Bar or Rebar. TMT bars are described as a high-strength reinforcement bar with a tough outer core and soft inner core. Since they have stepped into the market, they have proven to be extremely viable for reinforcing concrete structures.
Because of the features like high-strength, sturdy built and robust appearance TMT bars are proven to be the ideal bars for building earthquake-resistant structures. They not only help to minimize the effects of damages during any seismic activities but they also offer the perfect optimum balance between toughness and flexibility (Elongation).
Through the below points lets understand the difference between TMT vs TOR Steel
TENSILE STRENGTH:
TMT bars have higher value of tensile strength and yield-strength as compared to TOR steel. For an applied load on the structural element, usage of TMT bars will result in lower steel quantity whereas the use of TOR steel results in 20% more steel quantity.
DUCTILITY:
Ductility is the ability of any material to deform, without collapse even after reaching the failure point. TMT bars have more ductility as compared to TOR Steel which protect construction structures from structural collapse. Also due to extraordinary strength associated with TMT bars, they help a building structure acquire more strength.
ELONGATION:
Elongation is ability of any material to elongate before failure occurs. This factor plays a very important role in deciding ductility of any bar. The higher the elongation, the higher will be the ductility thus lesser will be the chances of occurring damage to any construction structure. TMT Bars have higher elongation compared to TOR which ensures safety of your constructions.
BENDABILITY:
Bendability is a very important factor when it comes to the properties related to bars. Because when building a construction, bars need to be given some specific bend to achieve required shape. TMT Bars have more bendability and re-bendability properties which makes them easiest materials to work with, which can be molded into any shape during construction.
WELDABILITY:
Lower the carbon content higher the weldability property which intern makes them easier for construction purposes. TMT Bars have low carbon content as compared to TOR steel thus TMT bars are the best choice for building constructions. Another important property is TMT bars require no pre or post-welding treatment, which makes them easier for construction purposes.
DURABILITY:
During any construction works, the TMT bars can stay exposed to water for a longer period without in any way getting affected. Traditional bars do not possess the anti-corrosive properties of TMT bars and hence remain vulnerable to rusting.
SEISMIC-RESISTANT:
TMT Bars are intrinsically hard and strong than TOR steel. Though TOR steels are strong, gradually they show softening behaviour which makes them vulnerable to earthquake shocks. TMT bars on the other hand can firm up the tensile strength to construction structures.
RUST RESISTANT:
High concentration of chloride ions present in the TOR steel makes the steel prone to corrosion. TOR steel corrodes in the concrete very quickly on the other hand, as TMT Bars are treated using Thermo Mechanically Treatment these are highly rust and corrosion resistant.
FIRE-RESISTANT:
Because of low thermal stability, TOR cant resist high thermal temperature. On the other hand, TMT bars with their higher thermal stability can retain more than 80% of the ambient temperature which helps the construction structures to stay safe and secure during fire disasters.
BONDING:
Because of high bonding capability as compared to TOR, TMT Bars allows to form a strong structure with concrete or cement, which intern provides superior strength to the construction thus increasing their longevity.
