The Dramatic Rise in demand for TMT Steel Bars in India

 

The introduction of Thermo Mechanically Treated (TMT) steel bars began a new era in the Indian construction industry. Round plain steel reigned supreme until the sixties but was then ousted by TOR steel in the seventies and maintained dominance until the nineties came into the picture. In the late nineties, TMT steel and corrosion resistance steel made their grand debut, transforming the face of RCC structure by making them more resilient and long-lasting. 

What Makes TMT Bars Stand Apart?

The term TMT bars has become the industry staple for constructing any structure, starting from bridges, flyovers, dams, hydel power plants, industrial structures, high-rise buildings, rapid transport systems, and more. TMT or Thermo Mechanically Treated bars uses Quenching and Tempering technology during production, obtaining their unique strength from that process. There is no chemical treatment involved in the manufacturing of TMT bars. 

But what gives TMT bar the unique edge that allows them to conquer the construction industry? 

Here are some of the attributes:

  • TMT bars’ carbon content is limited to 0.2% to achieve weldability and suffers no strength loss. 
  • Ordinary electrodes have the ability to weld joints without any extra precaution.
  • Due to their tough exterior and soft interiors, they have incredible ductility.

TMT bars tick all the three crucial boxes, strength, weldability and ductility, making them economical and safe for usage. A bonus is the corrosion resistance that TMT bars obtain since the cooling process avoids the formation of coarse carbide. The soft ferrite pearlite increases seismic loading. TMT bars are usually produced in Fe- 415, Fe – 500,  Fe – 550, Fe 500D, Fe 550D grades with diameter starting from 8,10,12,16,20,25, 28, 32, 36, 40 MM, with a standard length anywhere from 5.5 -13 metres.

TMT Bars and the Indian Market 

India’s iron and steel industry has come to occupy a dominant place in the country’s socio-economic development. India also ranks seventh as the largest crude steel-producing nation in the world. The Indian steel industry has gone through tumultuous business cycles, with several ups and downs. Today the industry is on the cusp of a significant change as it gears toward an expansion of ambitious standards. 

The secondary producers of the Indian steel industry are joining forces with the main producers. The emergence of the secondary producers has initially been modest in the post-liberalized decade in the steel scene. Still, it steadily contributes to the development of the domestic steel and iron industry in aspects of capacity, production, spread,  necessitation and commodity basket. 

Steel production in India received a massive boost with the introduction of the Industrial Policy Resolution of 1956. This is where the public sector saw three SAIL plants being set up in the late 1950s and the fourth one in the early !970s. These plants, along with VISL, TISCO and IISCO(now a part of SAIL), were the sole producers of integrated steel till the eighties (RINL came into production in the early nineties)  

There was a rising demand for the secondary sector for smaller-scale steel producers in the seventies. Specifically for those who had opted for induction furnace routes or the scrap-DRI based electric arc furnace, particularly for meeting local demands. 

Semi-finished billets and ingots manufactured by this part led to the commissioning of considerable re-rolling units to transform semi-finished steel into rods and bars that can be utilised mainly in the construction industry. 

The re-rolling part faced several market challenges, especially in high energy consumption and prices. However, there is a bright prospect of future growth, given the pace of construction and infrastructure activities. Experts estimate that the secondary producers in total crude steel production will increase from the current under -50% mark to at least 53%. 

We are also seeing an increase of foreign steel plants setting up steel plants in India, gearing up to venture into their dream project as the steel industry of India prepares for a new era. An era that will include the dominance of the Indian iron and steel industry. The steady growth of the Indian economy because of the steel industry has also increased infrastructure from township complexes to roads, bridges, and civil construction projects, which guarantees the continuous demand for TMT bars.

5 Best Reasons Why TMT Bar is the Future of the Steel and Construction Industry

 

The Indian construction industry has gone through a transformative phase since the late 1990s, both in technology and research. The proof of this rapid developmental stride is in the steel industry’s products- most of today’s products did not exist a decade ago. The industry has also made its presence in India’s numerous developmental plans in rural, urban and metropolitan areas. With the introduction of robust technological advancements, the popularity of steel products has also increased in the nation. 

But to be the future of any industry, products must meet the growing consumer demands and address the environmental factors. Historically, the steel industry has always been associated with ecological deterioration and destruction. To improve upon that aspect, the steel and construction industry worldwide has advanced into more environmentally conscious modes of production. The goal is to become more sustainable and reduce the industry’s carbon footprint. 

Here is where products such as the TMT bars come into action. TMT bars have proven to be the solution as the bars have adapted to future demands. Let us find out how they have proven to be a massive asset to the construction industry. 

What are TMT Bars?

Before we delve into the benefits, let’s find out all about TMT bars? ‘Thermo Mechanical Treatment’ bars, better known as TMT bars, are among the most necessary construction materials worldwide. They are high-strength reinforcement bars manufactured using a distinctive technique that endows them with a rigid outer surface and a soft internal core, making them strong yet flexible.

TMT bars are steel bars of a new era, suited for concrete reinforcement. These bars are employed widely in modern-day construction work, emphasising quality, safety, and longevity. 

Before TMT Bars

Before TMT bars came into the industry, Cold Twisted Deformed Bars, also known as CTD bars and M.S or Mild Steel Bars, were used for Reinforced Cement Concrete work. These bars failed to deliver on ductility and corrosion resistance compromising structural integrity in the long run. Hence, TMT bars came into existence to combat the downsides of previous construction materials and have now evolved into the most commonly used material for long-lasting structure construction. 

Why is TMT Bar The Future of the Industry?

When we observe the construction industry’s economy, we can witness the advent of the TMT (Thermo mechanically treated) steel bars. These bars are paving a new epoch of advanced growth and demand graph in the steel market.

Here is the reason why we are seeing such growth: 

1. Recyclability and Waste Management

The steel industry is circular, meaning that the generated waste can be used as an input in further production without losing its core properties. Therefore a waste generated can easily be melted and reconstructed, raising the rates of recovery in comparison to other products. It is also relatively easy to recover steel from other waste materials. At present, recycled steel represents as much as thirty percent of the whole new production process of steel making.

2. Longevity 

A key reason why TMT bars are becoming the face of the future of construction is their longevity. TMT bars production takes place, keeping in mind durability. Before TMT bars, iron rods were used in construction, making them prone to corrosion. For example, during the CTD bar manufacturing process, the method of twisting the rods negatively affects the ductility of the bar. It also breaks the protective blue oxide, making the CTD bars susceptible to corrosion.

On the other hand, TMT bars obtain anti-rust properties during the manufacturing process. Due to the intense cooling, coarse carbide, which is the foremost cause of the corrosion, does not get a chance to build up, creating the most durable bars. 

3. Strength 

Compared to ordinary reinforcement bars, the strength of TMT bars sets them apart and makes them the most suitable choice for any construction. The reason behind their strength and ductility is the extreme cooling it receives. The manufacturing process passes through a water cooling system which causes the outer surface to toughen. The ribbed texture of the TMT bar also allows better adhesion with the concrete, offering it more strength, while the flexibility makes it easier to work with. 

4. Disaster Resistant 

All scenarios are considered during construction, even the possibility of man-made or natural disasters. TMT bars are known to be earthquake and fire-resistant, making them a safer choice than other bars. 

The advantage of using TMT bars is their high thermal stability. Because of this property, they can tolerate severe temperatures varying from 400 to 600 degrees Celsius and maintain more than 80% of their ambient temperature yield strength at 300°.

TMT bars are a staple in earthquake-prone zones due to their ability to withstand high levels of stress and pressure because of their fatigue-resistant properties. The soft inner core and the rigid exterior make the bars very ductile, which permits them to absorb shock causing minimal damage to the structure.

5. Weldability 

Architects and engineers are looking to create more unorthodox and unique designs in this modern era without compromising basic structural integrity. TMT bars have high weldability because of the low carbon content. Also, since there is no pre or post-welding treatment, the process is more efficient for the workers.

The Future of TMT Bars

The growth potential of TMT bars is very promising, mainly because of the speed and scale of the infrastructure and the construction activities. Since India is still a budding market, construction-related works have a tremendous scope, which can pump the demand potential in the steel and TMT industry markets.

How Quality TMT Bar Adds Strength & Longevity to Construction

 

No matter how much you paint the walls or furnish the interiors, a weak structural foundation of any building can be detrimental to its strength and longevity. The only thing that guarantees your construction will survive the test of time is using good quality materials that make your base strong such as TMT bars.

What is a TMT Bar?

Before we delve into why and how quality TMT bars are crucial for your construction project, we need to learn all about TMT bars. 

TMT bars, also known as ‘Thermo Mechanical Treatment’ bars, is one of the most indispensable construction material worldwide. They are high-strength reinforcement bars manufactured using a unique technique that leaves them with a rigid outer surface and a soft inner core, making them strong yet flexible.

6 Advantages of Using Quality TMT Bars 

TMT bars are called the backbone of every RCC (Reinforced Cement Concrete) structure, but why? Let’s find out how these bars enhance a building’s longevity and strength.

1. Ductility and Strength 

Compared to regular reinforcement bars, the strength of TMT bars is what sets them apart and makes them the best choice for any structure. The reason for their strength and ductility is the intense cooling it receives. During the manufacturing process passes through a water cooling system which causes the outer surface to harden. The ribbed texture of the TMT bar also allows better bonding with the concrete giving it more strength, while the flexibility makes the bars easier to work with.

2. Corrosion Resistance

Based on the manufacturing process, the TMT bars anti-rust properties. Due to the intense colling, coarse carbide, which is the leading cause of the corrosion, does not get an opportunity to build up, making the bars more durable.

3. Fire Resistance

For a structure to have longevity, fire safety is a necessity. The perk of using TMT bars is their high thermal stability. Due to this, they can tolerate extreme temperatures ranging from 400 to 600 degrees Celsius and can retain more than 80% of their ambient temperature yield strength at 300°.

4. Weldability

TMT bars have high weldability; because of this quality, TMT is an exceptional choice for architects who intend to innovate and create unorthodox designs without compromising on the structural integrity of the building. The low carbon content not only makes weldability easier, but since there is no pre or post-welding treatment, it makes the process easier for the workers.

5. Earthquake Proof

TMT bars are favourite during construction projects is due to their ability to withstand high levels of stress and pressure because of their fatigue-resistant properties. One natural calamity that causes the most property damage is an earthquake. The soft inner core and the hard exterior make the bars very ductile, which allows them to absorb shock causing minimal damage to the property.

6. Cost-Effective

Because of its tensile strength, high elongation value, and uniform sectional weight per unit, using TMT bars in your construction project saves up to 20% steel, in turn saving money. Its high structural strength also reduces the cost of production. On top of that, these bars are easier to manage on-site, reducing the construction and fabrication costs.

The search for a quality TMT bar starts from its very inception. Known for its soft inner core and hard exterior, it will have no value if it is not manufactured correctly. TMT bars have an advanced manufacturing technique that includes three essential components: Quenching, Self-tempering, and Atmospheric cooling.

6 Ways TMT Bars Rolling Mills Reduce Manufacturing Costs

 

Rolling mills are critical products for the manufacturing industry. So if you have been searching the web to find all you can about TMT bar rolling mills, their applications in the manufacturing industry and the benefits they offer, read on. Here we bring to you everything you should know about TMT rolling mills – particularly about how they can help you reduce manufacturing costs.

What is a Rolling Mill and What is it used for?

In simple words, TMT rolling bars are used in the metal forming process. They are primarily responsible for reducing the thickness of metal and making it uniform across the length and breadth of metal, using a process called rolling. The rolling process also adds strength and durability to the steel. TMT bars that you see around you at construction sites are a product of this rolling process.

Rolling is of two types – Hot Rolling Process and Cold Rolling Process. Both processes are equally rewarding, and they, in their capacities, process more tonnage than any other manufacturing process.

However, there are distinct differences in metals that have been hot rolled or cold rolled. The hot rolling process makes the product more pliable and the surface of the metal, post-treatment, is not shiny. On the other hand, cold rolling yields a harder finished product with a distinct shine on the surface.

What are the Benefits of Rolling Mills?

The rolling aspect in the TMT manufacturing process offers several benefits – the most critical of them being the reduction in material wastage. Here is a glance at the general benefits of rolling:

  1. Rolling ensures that the metal has uniform thickness across its length and breadth
  2. A rolling mill saves you the cost of purchasing different and separate equipment. The same rollers can be used for the production of a wide range of components
  3. Close tolerance is possible for components in the rolling
  4. Saves time as high-speed production takes place in the rolling

How Can Rolling Reduce Costs?

Now that you have understood the generic benefits of using TMT rolling mills and the rolling process, here is the information you have been looking for all this while. Can rolling reduce costs? How?

Yes, rolling can save you a lot of money and here is how:

One of the most important products that come out of the rolling process is TMT Bars. These TMT bars are a preferred choice for most builders because of the strength, flexibility and durability it offers. So in a way, rolling mills can serve you a great deal by saving loads of money. Here is how:

1. Lesser quantity: 

TMT bar manufacturing machines lend TMT bars high tensile strength, which means they are stronger than any other ordinary steel. So TMT rolling mills help you by causing a tremendous drop in the amount of steel required for production.

2. Reduced Labour: 

Through the rolling process, high-performance TMT bars are made. These bars are extremely malleable, which means that they are easier in terms of handling by construction labour and easily transportable. This, significantly, reduces labour and construction costs.

3. Maintenance Savings: 

TMT Bars made in TMT rolling mills are corrosion-resistant. As a result, they stay robust longer even in the face of seasonal wear and tear. Hence, they offer greater RoI and require less maintenance and repair.

4. Protection During Earthquakes

One of the major concerns that manufacturers have to address during the production of construction materials is to ensure that they are earthquake resistant. The TMT manufacturing process strengthens TMT bars to ensure that they can withstand earthquakes efficiently.

5. Flexibility/Usage Benefits

TMT bars are extremely strong, offer flexibility and weldability without compromising on the core strength. This allows builders to not only build stronger structures but also experiment with various designs.

6. Transportation Savings

TMT bars are extremely lightweight and flexible, hence their transportation is easy. As a result, there are lesser labour and transportation costs.
