The strength of any building depends on the materials used. Tmt Steel is hands down one of the most widely used construction materials. Its strength, durability, ductility, corrosion resistance, fire resistance, and flexibility make it indispensable when developing a building. These are the reasons why it fares better than other steel. 

Though it comes with a flurry of attributes, flexibility is considered one of the best qualities of TMT Steel. The question is, “Why the hype for flexibility?”. Is it what you are wondering as well? Well, continue reading. In this blog, we explain why the flexibility of TMT Steel bars is a significant attribute. 

TMT Steel Bars In a Nutshell

TMT bars, also known as Thermo-Mechanically Treated bars, are solid and flexible steel bars heavily relied on by builders for construction purposes. TMT steel bars are a widely chosen material for various construction requirements ranging from minor slab construction to constructing large building structures. 

It’s the array of features TMT steel bars offer make it an ideal choice of steel. Firstly, it can resist heat and corrosion. Secondly, it’s cost-effective. TMT steel bars are also highly flexible, ductile, and offer great tensile strength. 

Why Flexibility of TMT Steel Is a Big Deal?

Now let’s see why the hype for the flexibility of TMT steel bars.

• You Can Bend It As Per Your Requirments

When we hear the word ‘flexibility’, the first thing that comes to mind is that TMT Steel can be twisted and bent into different shapes. Well, that’s true. You can bend it according to the structural requirements of the building. This is because its inner part is soft, unlike its outer part, which is solid. Moreover, this feature also makes it unbreakable.  

• Flexibility Also Suppress Pressure & Weight

When you use TMT steel bars, you could also expect your establishment to withhold weight and pressure assuming your building boasts high-quality TMT Steel bars. This also means that TMT Steel bars could help your building stay solid during natural calamities like earthquakes, cyclones, floods, or others, giving you peace of mind. 

Why? 

TMT Steel is ductile and has elongation properties. These attributes enable TMT Steel to stretch when there is an extra load to bear. Hence, it won’t break. All these are why flexibility is a salient feature of TMT Steel and why the majority of the builders opt for it. 

However, the TMT bar you buy must be high-grade to get the best out of it. You could check out some of the finest TMT Steel Bars at Kairali TMT. 

• Why Are TMT Steel Bars Flexible?

During production, thermal processing takes place where the steel goes through heat treatment and water quenching continuously. This is what gives strength and flexibility to TMT Steel bars. 

Here Is How the Process Works

1) Steel goes through heat treatment

2) Following that, it is quenched in water to cool down. This quenching process ensures that the steel’s outer surface hardens and the core part not only retains the heat but also becomes soft.

3) Next, the core part is let to supply heat to the surface. Thus, self-tempering happens.

4) Lastly, the steel goes through a cooling process where the core changes to a structure called ferrite-pearlite-crystal, which provides better flexibility, ductility, and elongation properties for the steel.
Simultaneously, the outer surface becomes solid. Altogether, the steel becomes flexible as well as strong enough to withstand tough conditions. 

More About Quenching Process

This quenching process is known as Thermex Quenching. It’s a process that changed the steel manufacturing industry. Before the arrival of the quenching process and TMT bars, only Cold Twisted Deformed bars were available. However, Cold Twisted Deformed bars are seldom used since TMT bars are low-cost, and offer better tensile strength, ductility, and flexibility. 

Are All TMT Steel Bars Flexible? 

You can rest assured that TMT Steel bars from top brands will be flexible and ductile. 

In fact, TMT bars go through a flexibility test called Bending & Re-bending, where the bar is bent 135 degrees and submerged in hot water for 30 mins. Afterward, the bar is re-bent to 157 degrees. This is how steel manufacturers ensure the flexibility of TMT steel bars. 

Wrapping Up

In a nutshell, one of the main reasons why TMT steel bars are used is because they can be bent according to the requirements, and they can defend a structure or building from natural calamities, all thanks to their flexibility. It’s the flexibility that enables you to shape the TMT bars and ensure the bars do not break, but rather expand and elongate when there is excessive force. And, this is why it’s said that flexibility is the most important feature of TMT steel bars. 

However, you ought to ensure you are buying high-grade TMT steel bars or your could not leverage these benefits. Kairali TMT offers high-quality TMT steel bars that conform to industry standards. If you require TMT steel bars, feel free to take a look at our offerings.
