Right TMT Grades to Withstand Earthquake

Right TMT Grades to Withstand Earthquake Fe415 Rightsteel

Steel is an indispensable part of construction. The possibilities presented by steel in the field of construction is not just limited to steel sections, but  also as steel bars as reinforcement to cement concrete in construction of structures. The story of steel as a reinforcement presents a picture of innovation in the field of construction. Starting as iron as reinforcement to structures, to highly ductile mild steel to deformed bars (High yield strength deformed bars) and finally to thermo mechanically treated (TMT) steel bars, showcase an evolution of steel reinforcements to keep up with the needs presented by humans in the field of construction.

Bendability of Reinforcement bars

Bendability of TMT reinforcement bars fe415 rightsteel

Construction of a house requires perfect planning and the sufficient strength to withstand loads of the structure and the certain natural disasters. In order to deliver such strength, the TMT steel reinforced bars are primarily used. Thermo Mechanically Treated (TMT) steel reinforced bars are known for their absolute strength and ductility. TMT is actually an innovated procedure performed on the hot rolled steel bars, which results in a strong outer martensite layer that deals the tensile strength and a soft ferrite-pearlite inner core which deals with the ductility factor. TMT reinforced steel bars are known for its Bendability.

Fe 415 Or Fe 500D For your Homes

Fe415 or Fe500 reinforcement tmt bars for construction of homes

This is two of the most used TMT bars when it comes to building homes in India and the average homeowners have a tough time getting their heads around to knowing their difference. So let’s begin with basics itself. Fe stands for Iron, the numbers 500 and 415 is their tensile strength and the ”D” stands for ductility. Here the word signifies the extra ductility which is generally not found in Fe 500. So why would steel companies go to the trouble of making a new grade of TMT bars instead of just promoting Fe 415? In this blog, we will try to find an answer for this conundrum.

First things first, these TMT bars are completely different due to the differences in their manufacturing process. It is where they are used is where the confusion arises. Fe 415 is a fan favourite among the average homeowner and Fe 500 is the choice for home contractors, this is mainly due to their combination of strength and ductility. Fe 500D seems to solve the problem of choosing between either strength or ductility. Fe 500 is perfect medium and small-sized commercial buildings as well as homes, and the Fe 500D can be used to construct both them, the versatility gives the Fe 500D an advantage of over Fe 500 but not over Fe 415.

Fe 415 is naturally more ductile than Fe 500D, while Fe 500D may seem like a combination of strength and ductility, it actually compromises between them. With Fe 415 homeowners get more ductility which can withstand earthquakes and other natural disasters. Fe 415 with its superior ductility can be made into shapes such as columns, slabs and other shapes. Fe 415 can be easily bent without needing the use for any bar bending and bar cutting machines as well. This significantly reduces the cost associated with building a home.

How TMT Bars Changed The Construction And Infrastructure Sector part 1

tmt bars best reinforcement bar for construction and infrastructure

Overview

India is one of the fastest growing economies, this means that construction sites are very common in India. From small-scale structures to massive infrastructure projects, India has rapidly increased its rate of urbanization from 11% in the late 1940s to 31% in 2018. This push towards to urbanization has been helped by many different factors, the government’s willingness to invest in infrastructure has been one of the important factors in this push. The real estate and the construction also helped this vision by actively taking part in this urbanization plan.

TMT Bars And Their Influence

TMT bars have become the backbone of every civil construction out there, they can give structures shapes, strength, and they can be moulded to make slabs, beams and columns as well.
As the expectations and demands of the common man rise with respect to make real estate structures. The need for high-quality materials for building structures has also gone, and this is one of the reasons why TMT bars have taken the centre stage in the construction field. TMT bars come in different grades so as to cater to different needs. These TMT bars have the approval of the Bureau of Indian Standards for building and construction projects. While Fe 415 is the popular choice among homeowners, Fe 500 and Fe 500D have carved out a market for themselves. In the blog, we will take a look Fe 500 and Fe 500D, just like Fe 415 they too are popular with a section of architects and engineers.

What are the different types of TMT bars?

Different-grades-tmt-bars-fe415-fe500-fe550-fe600

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.

Difference Between Fe 550 And Fe 500

Almost every modern structure made anywhere in the world nowadays contain TMT bars, they are right up there with concrete and bricks. Beyond a raw material, TMT bars can be used make beams. slabs, grids, columns and more. This makes TMT bars even more valuable. Even when TMT bars are bent to make secondary microstructures they do not lose their corrosion and anti-rust properties.

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.
