For decades, steel has been an integral part for all types of construction. It reinforces the concrete and protects the construction structure from getting worn out from rust or any natural calamity. Although it must be noted that there are different types of steel bars. The type of steel bars to be used depends on geographical and environmental factors. TOR steel was primarily used till the 1990s but soon TMT bars took over, their superior flexibility and other unique properties captured the entire market.
Tor Steel & TMT Bar
TOR came into reality after the brand name ‘Toristeg Steel Corporation’ of Luxembourg. Because of high adherence, TOR was one of the best grades of steel used in 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.
Whereas,
Thermo Mechanically Treated or TMT bars are high-strength support bars that feature a tough outer core and a soft inner core. Known for their superior strength, corrosion resistance, and fire-resistance properties, TMT bars are capable of providing better reinforcement to any concrete structure and are ideal for constructing earthquake-resistant structures.
The below points will help you to understand the difference between TOR &TMT Bars.
Ductility
TMT bars have more ductility as compared to TOR Steel which protects construction structures from structural collapse. Also due to the extraordinary strength associated with TMT bars, they help a building structure acquire more strength.
Elongation
Elongation means the ability of any material to elongate before failure. The higher the elongation, the higher will be the ductility. When compared to TOR Steel, TMT bars have a hard outer layer and a soft inner core. And this makes construction structures strong and flexible.
Tensile Strength
TMT bars have a higher value of yield strength when compared to TOR steel as it has 2 layers of the soft inner core and hard outer core that can withstand external force and stress.
Seismic-Resistant
TMT bars are intrinsically hard and strong than TOR steel. TOR steel softens in the long run and makes them vulnerable. On the other hand, TMT bars with their excellent concrete bond of soft ferrite-pearlite core and reinforcement strength.
Fire-resistant
TOR steel contains low thermal resistant capability. On the other hand, the best TMT bars are highly thermal/fire resistant and can absorb heat up to massive 600 degree Celsius. Using TMT bars for construction makes your building highly fire-resistant.
Conclusion
The above points clearly illustrate the difference between TMT bars and TOR steel bars and why TMT bars are far better than the latter.
