TMT Bars: Unique Features that Make it an Indispensable Construction Material


TMT bars are the most crucial factors in determining the durability and strength of the concrete structure. These bars form the basic structure of the building and are used widely for their earthquake-resistant quality. That’s why before buying TMT bars, ensure that you are buying from the best TMT bars manufacturers.

There are certain reasons that make TMT bars a crucial factor for any construction. Let’s take a look:

1. TMT bars ductile. These bars are available in many grades including Fe-415/500/550. Compared to conventional reinforcement bars, TMT bars are extremely strong. Higher the grade, better the strength. All the major construction projects in India use TMT bars. Before buying TMT bars check the list of best TMT bars companies in India and buy from them. SRMB is one of the best TMT bar companies in India and is famous for produce high-quality TMT bars. To check their products, visit

2. TMT bars are cost effective. This is because compared to conventional bar you can save about 20% of steel. Moreover, TMT bars give you 20% stronger structure with the same amount of steel. This helps in keeping your production costs low.

3. TMT bars are resistant to Fire. This is another exclusive quality of TMT bars. They can withstand extreme heat and that’s why they can survive any fire hazard. This is another reason why TMT bars are mostly preferred in the construction industry.

4. TMT Bars can withstand fatigue. This is another important quality and this is what makes TMT bars the best option for construction in earthquake-prone zones. TMT bars can absorb a huge amount of shock and have excellent bending and re-bending properties. The core of the TMT bars is softer and it has a strong outer core. This makes them withstanding high-degree of pressure.

5. TMT Bars are manufactured through a unique Tempcore technology. This makes the bars corrosion-resistant. TMT bars are exposed to moisture during construction projects and the anti-corrosion properties help prevent rusting. Conventional bars do not have this property and this makes them vulnerable to rusting.

6. TMT Bars have superior weldability. And that’s why the civil engineers and architects can design innovative structures using these bars without compromising the strength of the bar and the structure quality.

7. Unlike conventional bars, the steel rods are not twisted during the manufacturing process of the TMT bars. That’s the reason the TMT bars do not have any residual stress. This unique manufacturing technique gives them corrosion-resistant property.

8. High elongation power is another unique feature of the TMT bars. This is the quality to deform before the bar breaks. High elongation power protects the building from any damage during natural calamity such as an earthquake.

These unique features make TMT bars apt for any kind of construction. Before buying TMT bars, determine the grade that you’ll need for the construction. And do not forget to check the quality of the bar before buying.


5 Steel Manufacturing Facts


From centuries, humans are experimenting with the steel making process. Fuelled by innovation, the manufacturing process of steel has come a long way. Today, it has evolved as the most important industries across nations and is a key contributor to their economies. Steel is extremely versatile and its unique properties and strength set it apart from any other material.

The manufacturing of steel involves a number of processes. It has come a long way since ancient times. Let’s take a look at the facts on steel manufacturing:

Modern Steel Making Process

1. Iron-making

Iron is the basic material out of which steel is made. This is the first step. First, the iron ore is blended with raw material such as lime and coke. This mixture is then melted in the blast furnace. The end product is known as “sinter.” This process helps in reducing the levels waste and impurities. This molten iron contains about 4-4.5% carbon along with other impurities.

2. Primary Steelmaking

This is the next step in the manufacturing process of steel. This step involves two ways. One is the BOS method where the recycled scrap steel is mixed with the molten iron. After this, oxygen is blown through that mixture at an extreme temperature, thus reducing the carbon content of the mixture. Another method is the EAF method. This is a process where the steel scraps are fed through electric arcs on high power. This melts the metal and converts the metal into high-quality steel.

3. Secondary Steelmaking

This is the third step in the manufacturing process. The steel that is produced using both the BOS and EAF method is then subject to treatment. This is for adjusting the composition of the steel. Certain elements are added to the steel and several are removed from it. Even the temperature is sometimes manipulated along with the environment of production.

4. Casting of the molten steel

In this step, the molten steel is then put into moulds and is allowed to solidify. Guided rolls are used for withdrawing the shell strand. It is subject to further cooling and then the strand is cut. The length of the strand depends on the application of the steel.

5. Hot Rolling

The steel is given various shapes using the hot rolling process. This step is essential for removing any casting defects. The steel is given the desired shape and achieves better surface quality.

Steel Manufacturers in India

TMT bars, an important component for construction, are manufactured from steel. However, the innovative techniques used by the leading steel makers determine the quality of the bars thus produced. When buying TMT bars for your home, always check the brand and buy only from authorised TMT bars suppliers. If you are planning to buy TMT bars, check the products manufactured by SRMB at

History of Steel Industry in India: 10 points


The Iron and Steel industry are the two most important and basic industries in India. These are also one of the main contributors to the economic development of the country. From construction to manufacturing, almost all industries have to depend on them. But have you ever wondered, how old is the steel industry in India?

Here’s a brief overview:

1. History of steel in India dates back to 400 BC. At that time, Indian archers were a part of the Greek army. They used arrows tipped with steel. There is much more evidence that Indians had the knowledge of steel-making even before the advent of Christ. Archeologists discovered many pieces of evidence in Mesopotamia and Egypt that prove the fact that mankind knew the usage of iron and steel for more than 6,000 years.

2. It was in 1874 when the first attempt to revive the steel industry in India was made. In that year the Bengal Iron Works (BIW) started its journey at Kulti in Asansol, West Bengal. However, in 1830 a foreigner called Joshua Marshall Heath set up a small steel manufacturing plant at Porto Novo, Madras.

3. The BIW was acquired by Bengal Iron and Steel Company in 1889. Soon, it became a success story. In 1900, the plant produced 40,000 tonnes of pig iron. It continued to produce steel; Indian Iron and Steel Company (IISCO) acquired it in 1936.

4. August 1907 was a golden day for India’s iron and steel industry. It was on that day when the Tata Iron and Steel Company (TISCO) were formed. It was formed as a Swadeshi venture and was supposed to produce 120,000 tonnes of pig iron.

5. The then Prime Minister of India Jawaharlal Nehru believed that for development, India needs to maximize its steel production. It was then he formed a Government owned company called Hindustan Steel Limited (HSL). Three steel plants were set up in the 1950s.

6. The government changed their industrial policy once in 1956 and then in 1991. From 1992, Iron and steel industry was included in the list of “High Priority” industry. The policies bore fruit very soon. In 1997-98, India’s steel production went up to 23.37 million tonnes from a mere 1.1 million tonnes in1951.

4 Facts on Disastrous Earthquake That Hit Nepal in 2015


On April 25th, 2015, a devastating earthquake ravaged Nepal. It killed about 9000 people and injured a thousand others. More than 600,000 concrete buildings and other structures were damaged all across Nepal. The earthquake was so strong that the vibrations were felt as far as the Northern part of India and the North-western parts of Bangladesh including Western Bhutan and Southern parts of the Tibet plateau.

Devastating Nepal Earthquake


Here are a few more facts about the devastating earthquake:

Weak Infrastructure

The infrastructure of Nepal was very weak when the earthquake struck the Himalayan country. The majority of the houses and other structures were built without following a proper building code and also using low-quality construction materials. In 1994, the administration of Nepal tried to implement a building code following another earthquake; however, it turned out to be unenforceable. In majority of the cases, falling debris of the houses kills more people than the earthquake itself. And that’s why it is important to use good quality building material such as earthquake resistant TMT bars must be used to construct a house.

Earthquake resistant TMT bars have higher elongation as they have a soft ferrite-pearlite core and a tough exterior. These can withstand pressure (including seismic shaking, thus making it safe for being used in earthquake-prone zones. If you are looking for higher elongation TMT bars in West Bengal or Nepal, check the products from SRMB. For more details, visit

The Magnitude

The initial shock that struck the country was measured at 7.8 on the Richter scale. It struck shortly after noon, and its epicentre was about 34 kilometres East-Southeast of Lamjung in Nepal and was about 77 kilometres north-west of the capital city of Kathmandu. Within an hour of the initial shock, two shocks of magnitudes 6.6 and 6.7 shook the region. During the following days, the country experienced some smaller aftershocks.

The Cause

The Nepal earthquake and the resulting aftershocks were caused by a thrust in the fault line in the Indus-Yarlung suture zone. This area lies in the East-West region and is near about the length of the Himalayan range. The earthquake is said to relieve the compressional pressure that developed between the Indian section of Indo-Australian plate and the Eurasian tectonic plate.


Death Toll

About 9,000 people were killed in Nepal alone, and more than 10,000 people were injured. When the earthquake struck Nepal, it resulted in an avalanche in the Mount Everest. 18 mountaineers died in their base camp in that avalanche. About 75 people in India were killed due to the vibrations, and 25 people in China lost their lives.


Shift in Earth’s surface

The Nepal earthquake was so strong that it resulted in a shift in the Earth’s surface. It is reported that the Earth’s surface shifted about 3 metres in 7,200 kilometres. A few parts of the capital city of Kathmandu is said to be lifted by about 3 feet vertically. This caused immense damage in Kathmandu.

Hopefully, these facts have helped you gain some insights into the damaging effects of the earthquake in Nepal.

How to Select TMT Bars Manufacturers?


When constructing a home or a concrete structure, it is important that your select the right building materials especially TMT bars. It’s because the quality and strength of the TMT bars have a direct implication on the strength of the concrete structure. There are many TMT bar manufacturers in the market, but you need to ensure that you choose the best brand.


Here are a few tips to help you choose the right TMT bar manufacturer:

Check the Grades

The grades of TMT bars are essential in determining their strength. In India, TMT bars are available in a variety of grades such as Fe-415/500/500 and 600. The higher the grade, the stronger the bar. When selecting a TMT bar manufacturer, check whether they offer bars of superior grade or not. SRMB, one of the leading TMT bar manufacturers in India, manufactures TMT bars of superior grade that provide ultimate reinforcement to the concrete structure.

Certification of the Company

Always buy from ISO certified brands. TMT bar manufacturers who are ISO certified always maintain strict quality control, complete safety and security of the product. Also, when buying TMT bars, always buy from the authorised dealer of the manufacturer. In this regard, SRMB uses advanced Tempcore technology for manufacturing their TMT bars and their manufacturing plants are BIS and MIS certified (ISO: 9001, ISO:14001, and OSHAS: 18001). Moreover, SRMB is the first brand to implement TMT process control technology from CRM, Belgium. Also, it’s one of the first TMT bar manufacturers in India that installed “no twist V-block mill”, a high precision rolling mill for manufacturing TMT bars.

Conduct a Naked Eye Test

This is one of the many ways of selecting a TMT bar. When evaluating bars from different manufacturers conduct naked eye test. Every metre of the TMT bar should bear the logo of the company. The TMT bars should be free from rust coating and must look fresh. The ends of each bundle must be of equal length. SRMB TMT Bars are corrosion resistant and come with a water-resistant coating.

Due to their superior quality, SRMB TMT bars are preferred by the big names in the company. Some of the big names that prefer SRMB TMT Bars include Aecom, Scott Wilson, Bharat Petroleum, and Chennai Metro Rail Limited, to name a few.

Selecting the best TMT bar manufacturer will ensure that the concrete structure lasts for long.

Planning to Build a Home? Know The Facts of Construction Materials


Construction materials are important factors in deciding the quality of the structure. If the construction materials are not carefully chosen, the safety and security of the concrete structure are endangered. So, when planning a construction, the materials must be carefully chosen to avoid any kind of mishap. From TMT steel bars to bricks, there are many construction materials that are widely used for building homes and multi-storey buildings.

Construction Materials-TMT Bars

Here are a few facts about the commonly used building materials:

TMT Bars

From homes to bridges, TMT bar is commonly used in almost all type of construction. The manufacturing method of TMT bar follows processes such as compressing, rolling them in the mill, heat treatment followed by an intense quenching process with Tempcore system. The quenching process hardens the surface of the TMT bars, leaving the core of the bars soft. This process makes the TMT bars extremely durable and delivers superior strength. Also, it makes the bars ductile and gives it high bendability. Moreover, the ribbed surface of the bars helps form strong bond with the concrete, thus providing extreme strength to the concrete structure. For these reasons, TMT bars are highly preferred in zones prone to seismic activities.


This is a commonly used building material. Concrete is manufactured by mixing binder (such as cement) and aggregate composites. There are many types of concrete such as Rapid-setting concrete, fluid-fill concrete, Portland cement concrete, Roller-compacted concrete, to name a few. Among all, Portland cement concrete is commonly used in construction work. This cement is made of cement, sand, water, and gravel. After mixing all these components together, the mixture is hardened. The solid mass thus obtained is knows as concrete. Concrete has very low tensile strength. However, it’s highly durable and ensures longevity of the building.


Bricks, be it of clay or mud, or of ceramic material, is one of the most basic and essential construction materials. No construction is complete without bricks. These are used to make walls, roofs, partitions and other components of a house or building. Bricks are made by burning clay, mud or ceramic material in a brick kiln and then drying them to make them hard. The most common kind of bricks used for construction purpose is fired bricks. It’s because these bricks have cavities and thus, dries at a faster pace. Bricks are reinforced using a mixture of sand and cement and are placed upon one another for making walls and other parts of a building.


Cement is basically used to bind and reinforce all the construction materials such as TMT bars and bricks together. Cement is of two types:

  • Hydraulic Cement: this type of cement has adhesive properties and sets well with water.
  • Non-Hydraulic cement: It is a cheaper alternative to hydraulic cement and doesn’t harden with water.

Hydraulic cement is widely used for construction purpose.

We hope that these points will help shed some light on the various construction materials and their unique properties.

5 Facts on TMT Bars

TMT bars

Thermo-Mechanically treated bars, popularly known as TMT bars are the most common construction materials used in many construction projects worldwide. These are highly preferred due to their superior strength and strong bonding with the concrete.

Let’s take a look at a few interesting facts about TMT bars:

High Strength bar

TMT bars are Thermo-Mechanically treated through a unique Tempcore technology that delivers a high strength to these bars. This process involves quick quenching of the extremely hot steel bars just after they roll out from the rolling mill. The bars are made to pass through a sequence of water jets which turns their outer layer extremely hard leaving their inner core soft. This makes the TMT bars highly ductile and makes them extremely strong. If you want to buy TMT bars, check the bars from SRMB, one of the topmost TMT bar manufacturers in India.

Corrosion Resistant properties

During the manufacturing process of the TMT bars, these bars are never twisted like the steel bars of yesteryear. This makes the TMT bars devoid of any residual stress. Moreover, during the quenching process of the TMT bars, the controlled water-cooling prohibits the formation of coarse carbides which is the main reason behind the corrosive process of the steel bars. This makes the TMT bars resistant to corrosion. During construction of houses or any other structure, the TMT bars are exposed to water for longer periods but rust never forms on the surface of the TMT bars. Corrosion is a common issue in case of ordinary steel bars. And that is why using ordinary steel bars can endanger the safety and security of the structure.

High Ductility

TMT bars have high ductility. You will get TMT bars in a number of grades such as Fe- 415/500/550. These TMT bars are stronger than ordinary steel bars. And that is why all the major construction projects use TMT bars for their construction.

They have flexible bending ability

TMT bars have extremely high bending ability. And that is the reason TMT bars allows ease of use. One can easily mould the TMT bars in various shapes. Also, these can be stretched to meet the unique demands of construction measurements.

TMT bars are earthquake-resistant

Do you know that TMT bars are resistant to an earthquake? These bars have soft inside and tough outer layer. Also, these have superior elongation which makes it extremely flexible. This, in turn, gives high flexibility to the concrete structure. The fatigue resistance property of the TMT bars enables them to bear seismic loading. And that is why TMT bars are highly preferred and recommended for construction in areas that are prone to earthquake.

Also, TMT bars have thermal resistant properties which make them a safe choice for fire hazards. We hope that these points will help you understand the unique features of TMT bars.
