Different Types of TMT Bars
TMT Steel bars not only provide solidity to the buildings but also inordinate strength to them. They are also known as Thermo Mechanically Treated bars. They were presented to the construction world for the initial time in the year 1979. They are manufactured by means of high-grade steel, possess greater strength and are said to raise the structural firmness of the structure to a great degree. The exclusive manufacturing process guarantees higher flexibility as well as bendability by virtue of recollecting a softer inner core while the outer core is quite hard.
In layman terms, TMT Steel Bar retain the concrete intact and deliver stability to the whole structure.
Significance of TMT Bars in Construction
These bars are tremendously important as the offer higher stability to the building. They do so by counterattacking bending, compression along with slanting resist clipping forces while bearing the complete load of the edifice on them.
The numerous types of loads it takes on are live load, wind load, dead load in addition to earthquake load.
Different Forms of TMT Bars:
Fe-415, Fe-500, Fe-550 along with Fe-600 are the four diverse types of TMT steel bar grades shaped by TMT steel bar producers in India.
The dissimilar grades of the steel bar specify its strength and stiffness factors. The number represented the force that requires to be applied in order to distort or modify the steel bars for several purposes.
Smaller grades of bars are applied for small constructions for example homes whereas the advanced grades are utilized for heavy construction for example multi-storey buildings, bridges as well as even dams etc.
Advanced grades of TMT steel bars are also employed for creating the core of structures for robust flooring, roofs etc. Railing in addition to other decorative structures are constructed with smaller grades of steel bars since they do not claim high strength and the capacity to bear harsh weather conditions.
One would need different grades of TMT steel bars for diverse areas of applications while erecting a building.
Grades of TMT Steel Bars and Its Applications
- FE 415 GRADE
These TMT steel bars possess greater elongation properties and are frugally possible making them the finest choice for small buildings. They are favoured for areas disposed to to natural disasters such as earthquakes. It comes with corrosion resilient properties.
- FE 500 GRADE
These steel bars are acknowledged for their flexibility making them the perfect choice for underground constructions as well as multi-story buildings. They have good steadiness and pliability and offer high seismic safety from earthquakes along with other natural disasters.
- FE 550 GRADE
These TMT steel bars have greater tensile strength as well as are put into bids where Fe-500 grade turns out to be a little difficult to achieve. Illustrations of Fe-550 grade applications are marine structures.
- FE 600 GRADE
These TMT steel bars have the uppermost Tensile to harvest strength, ductility and elongation associated with all other grades of these steel bars. This grade of the steel bars comes into application for heavy constructions that need maximum strength and toughness that lasts for a lifetime and resist harsh weather conditions as well as earthquakes.
