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.

Soil Factors To Consider – Part 1

Soil-factors-construction-piling

But even before the foundation works starts, it is very important to understand the local soil and the site factors that come together with the soil. This will help engineers to avoid any unforeseen circumstances, some clients and site engineers conduct soil test before the construction of the structure. It is generally a wise move to perform a soil test before starting the construction. Below are some of critical individual factors to consider before building a home.

TMT Bars and Galvanic Corrosion

tmt-bars-prevents-galvanic-corrosion

The Problem

When the word corrosion pops up, we think of corrosion of metals due is to constant interaction with air (much more specifically oxygen), corrosion is the process of the metal actually becoming stable than its refined state. The corrosion we are discussing here is entirely different, galvanic corrosion occurs when 2 metal is in contact for a long duration of time. This happens due to the fact that different metals have different electrochemical properties. The metals act as anode and cathode and the process of stabilizing the metals start, meaning by which is corrosion.

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.

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.
