The introduction of reinforcement drastically changed the phase of construction of building structures of steel. Reinforced steel provided the necessary tensile strength which the concrete lacks. Today, very few constructions are done without using reinforced cement concrete. At the current scenario, the most used reinforced steel bars are the Thermomechanically Treated (TMT) steel reinforced bars. They are preferred for their excellent tensile strength and optimum ductility. The TMT steel bars are of different grades namely Fe 415, Fe 500, Fe 550 and Fe 600.
The Part-I of this blog explained about the two most important factors to be considered in a TMT steel reinforced bar which was Tensile strength and Ductility. Also, a brief introduction of Ductility was described. The hot and soft inner ferrite-pearlite core is responsible for endowing the reinforced bar with optimum ductility. The ductility is not something that should be neglected. It is an integral part of handling the forces or loads of a building structure.
Reinforced steel bars, the supporting platforms in the construction of modern building structures. The current innovation in reinforcement steel is the TMT steel reinforced bars. Known for their unparalleled tensile strength and ductility factor, reinforced steel bars have literally dominated the construction sector in India and all over the world.
With the ever-increasing demand of Steel for the visionary development around the globe, this reliable metal has been undergoing constant up-gradations and newer technologies and processes are being used for its manufacturing. With 1500 types of high-grade Steel available around the globe, there is immense growth seen to fulfill the different requirements Steel can cater to for development and infrastructure for the modern world.
Steel grading is one of the main characteristics used for selection of Steel for the different purposes. These grading systems are developed by National and International Standard organizations to ensure standard categorization and aid selection of Steel for their purpose.
Buying or building a house can be a daunting decision which carries a long-term financial implication. Owning a home has become relatively easy when compared with olden days, whether be it financial institutions who have made the dream of owning a home more affordable and governments have helped this cause by imposing stricter guidelines when it construction safety standards. The remaining problems are of longevity and the complexity of the structures.
TMT bars have changed how homeowners look at these problems, they as in TMT bars have greatly reduced the prices associated with purchasing and building homes, all while making homes safer and long-lasting, in short, TMT bars have made homes as a perfect investment. Before getting to know TMT bars in detail with respect to their types and grades, let’s just go through why TMT bars are better than iron rods by default. TMT bars have been accepted by civil engineers, contractors and even by governments. Below are some of the advantages of TMT bars over iron rods.
There was a time when homes and commercial buildings in India was built with unprocessed iron rods and concrete slabs. The problem with this process was that rods would soon begin to rust away much more earlier than expected. This, in turn, affects the stability of the structures in the long run. Making them unsafe, unreliable, prone to frequent repairs, leakage due to rains and general dissatisfaction of the owner. TMT bars is a solution for all the above-mentioned problems, they are made according to universal standards of strength, rigidity and flexibility. The arrival of TMT bars has made structures more safe and reliable across acts of god. TMT Steel bars have also changed how we use concrete, instead of slabs, we now use concrete bars for better overall results.
