To understand why TMT is so popular, what part of its manufacture makes the real difference, and where using these bars is beneficial, stay with us until the end. You will certainly know why TMT bars are worth it. Follow along!
What makes the difference?
The production of TMT steel implies that the processes of mechanical and thermal deformation take place simultaneously. Compression and rolling mechanical deformation steps along with thermal deformation processes such as heat treatment followed by quenching occur in a single course during the production of TMT steel bars.
After hardening the metal by heating the core area, the quenching process is immediately done in air. This allows tempering of the metal to take place, so that stable martensite is eventually produced. It is this procedure that adds hardness to the steel because it reduces internal stresses and brittleness. Also, since the process involves strengthening the ferrite phase, we get added levels of toughness in the final product.
As a leading producer of the best TMT bar in Kerala and South India, Pulkit TMT uses modern manufacturing techniques to produce steel bars that are more viable for industrial and residential projects.
Why are TMT steel bars popular?
In India, TMT steel bars are available in various shapes and grades. All of the different types of TMT bars have certain specific benefits to offer, making them a popular choice for construction. Check out the benefits of these grades to choose the best steel for home construction and industrial work.
Benefits of Fe-500 D
Although the grade of these TMT steel bars is low, they possess excellent uniform elongation capabilities and superior ductility. Their remarkable resistance to aging makes them a necessary building material for RCC projects in corrosion-prone areas.
Benefits of Fe-550 D
Builders prefer to use Fe-550 D as it adds to the advantages of Fe-500. With an impressive yield strength of 550 N/mm2, these TMT bars or CRS Bars in South India provide comprehensive benefits as they are strong, resist dynamic loading and are even corrosion resistant. The 'D' here denotes ductility, indicating its superior elongation qualities. This is why they are the best TMT steel bars for RCC constructions in earthquake prone locations.
Benefits of Fe-500 S
The 'S' in 500 S denotes superior tolerance to saline environments. This makes them suitable for construction in coastal areas. These bars have a great tensile strength to yield strength ratio, which infuses them with a considerable amount of toughness. They even provide decent protection against lateral buffeting and can also withstand large amounts of disruptive forces.
Most popular use cases of TMT bars
From what we have discussed so far, it is evident that TMT steel bars manufacturers offer full benefits for construction. It is the reason why almost all large and small scale construction activities use TMT steel in one form or another.
Since TMT bars such as Fe-550 D possess extremely high durability, they are used in colossal projects such as power plants, dams, airports, stadiums, highways, etc. Here, the main purpose of using TMT bars is not only to increase longevity, but also to ensure the safety of the common public.
Construction of a residential complex in an otherwise earthquake-prone region will also require TMT steel bars. The malleable and flexible nature of these bars allows them to be easily bent or shaped according to building and architectural plans.
