Introduction

The TMT in TMT Bars stand for Thermo-Mechanically Treated, it is a process of rapidly cooling down bars in the molten state. This cooling down process is either done spraying water at regular intervals. This regular interval will further define the characteristics of the bars. This interval of quenching of bars will give rise to different grades of TMT bars in fact.  The goal here is to have a solid and hard outer surface with a pliable inner core. This outer shell is coated with a protective film, making them resistant to corrosion and rust, making them apt for constructing sensitive structures such as high rise residential buildings and bridges in humid areas. TMT bars and different Steel Grades.

Fe 415 and Fe 500 – The Common man’s TMT Bars

Where It’s Used

When building a home, a common man looks for a home which will last a long time, wants to have his/her influence on the designs and doesn’t have a lot of money to throw around. To accommodate these needs, the common looks to Fe 415 and Fe 500. These TMT bars have the ability to tick all the boxes of expectations and demands of the common man such as design influence, cost dependability, and maximum usage of the available space. The reason why these bars have to say even space is a concern is this, even though the number of TMT bars needed may reduce but these bars are purpose made for small structures.

Properties of Fe 415 Steel Grades

Introductions

TMT bars of the same grade usually have more than one type, while it is uncommon to hear about Fe 415D or Fe 415S. One must surely be heard of Fe 500 and Fe 500D, here Fe stands for iron, 500 stands for the tensile strength and D stands for ductility. Other than the names they also have a different chemical composition as well. When talking about carbon content Fe 415 has a maximum per cent 0.30 carbon while Fe 415 D and Fe415 S has a maximum carbon per cent of 0.25.

In this blog we will be taking a close look at Fe 415, the choice of the common man/ woman for building his/her dream home. We will taking a detailed look on how different grades of steel react to different standards tests undertaken by the Government of India. The number 415 in this grade of steel simply refers to its yield strength. Below some of the characteristics by different grades are marked.

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.

Based On Structures

Fe 415 and Fe 500 are the TMT bars made for the common man, what a common dreams off is a home or a small scale commercial structure. What to choose to based is based on many different criteria and the prevailing geographical conditions. Beyond the the structures there is wriggle room both for owners and architects to choose between Fe 415 and Fe 500, looking at the cost and the timeline for the construction also comes into the picture.

Things to Remember Before Bending TMT bars

Rust

It is expected that in construction there will become unexpected surprises and in one of those many unexpected surprises not many of the same long-term effects as the need to bend TMT bars. Bending TMT bar is a tricky skill, there are some obvious downsides such as broken TMT bars. The long-term negative effects come from the breaking of the protective film from the surface of the TMT bars. These films are coats of special paints which does rust or corrosion to happen. This happens as TMT bars have a strong shell and a soft inner core, while outer shell can withstand rust and corrosion for a long long time as they come prepared with a protective coating.

Concrete is the heart and soul of any construction project, they can moulded into almost shape and can withstand anything weather and climate around the world. But, what the concrete lacks is the strength, ductility and a low tensile strength. This is where TMT bars come to save the day, a mix of concrete and TMT bars can help engineers to build structures like never before in the history of mankind.

TMT Bars – Thermo-Mechanically Treated Bars – An Introduction

tmt-bar

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.
