Constructing buildings is not an easy task, It requires a lot of resources, technical skills, dedication and commitment. When we talk about the resources, the most vital components for constructing buildings are reinforced steel and concrete. Reinforced steel is primarily known for its excellent strength and ductility which provides the necessary strength to withstand the load of the structure. However, there are several factors that can affect the strength of the steel in such a way that it becomes extremely dangerous to the whole structure, and one such factor is rusting.
Use of Thermo Mechanically Treated (TMT) reinforced bars for construction is now a standard practice. With newer technologies developing, it results in efficient constructions strategies which in turn improves the lifespan and structural integrity of the building structure. However strong the building structure claims to be, in order to for its longevity the building structure has to face several hurdles, even the natural disasters.
Nowadays TMT steels are commonly used in constructions. What is TMT? Why is it used than other types of steel? Well, before TMT was introduced Mild Steel (MS) bars, Cold Twisted Deformed (CTD) bars were primarily used with concrete for constructing buildings. Those steel were graded Fe 250 but their low strength was a problem for buildings requiring more strength.
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.
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.
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.
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.
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.
Before getting to know TMT bars in detail, lets 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.
