Before we begin, let’s get a brief knowledge about TMT Bars. Well, for starters, these bars are manufactured through a process called Thermo mechanical processing, where mechanical and thermal processes are combined to form high-quality rebars. This is done to determine how strong and flexible the product is by involving stages like water quenching, heat treatments, rolling, and atmospheric cooling. The quality of the bar is then determined upon the quality of raw materials, rolling mills that give out its shape and the system used for tempering and quenching the product.

Process of Manufacturing

The raw materials that are used to manufacture TMT Bars are Coal, Dolomite and Iron Ore. Firstly, the three materials are mixed together in equal proportions, and the metal fines present in the materials are gathered together to shape the pellets and sinter to increase efficiency. While that happens, coal is turned into coke and are all together added into the furnace along with limestone to melt. During this process, the impurities present in the limestone also get separated.

Finally, the furnace combines the oxygen with the carbon present in iron to eliminate CO2 (Carbon Dioxide), which is also known as pre-treatment of the initial product. After that, the molten steel is passed through an electric arc furnace, where liquid steel flows into the casting ladle, and from there it is dropped into a cooling mould to solidify.

TMT (Thermo Mechanical Treatment)

• ✓ Quenching: Once the mill releases hot-rolled bars, they enter the Thermex System, where the bars are cooled down with the help of high-end technologies to ensure ductility in the product. This process helps to harden the outer layer of the bar while keeping the inside core hot.
• ✓ Tempering: As the inside core still remain hot after the quenching process, it is kept aside for the heat to flow to the surface, causing create an outer layer structure called Tempered Martensite.
• ✓ Cooling: Finally, the bars are sent out for atmospheric cooling, which is done by placing them on cooling beds at room temperature. During this process, the core forms a two-layered structure, making the outer layer of the TMT Bar a high-quality ductile product. At the same time, it also helps in increasing its tensile strength.

ARS Steel

While the whole process of manufacturing is intense and requires a good amount of experience and knowledge, there are only a few industries out there that carefully focuses on the process to ensure high-quality TMT Bars. One of which is the ARS Group of Steel, an industry that was established in the late nineties to become one of the top steel manufacturing hubs in South India. Although their main focus was on Tamil Nadu, they’ve now grown to a level where they plan to expand their company abroad.

Thanks to the upgraded 25MT furnace, which has a capacity to produce 2,50,000 MTPA, the TMT 550D Steel Bars created are highly resistant to climatic disasters, as well as corrosions, and includes the right proportion of chemical properties needed to obtain a premium quality. They’re quite cost-efficient due to the ductility present in them, which results in less consumption of bars, and reduced labour.

For a successful construction, you must first be able to identify the best steel that can be used in the building of your home. TMT Bars, also known as Thermo Mechanically Treated Bars is a rising product in the market today, known for its high resistance and strong structure. Searching for the right material often consumes a lot of time, but you don’t have to worry about that, because ARS Steel, one of the largest steel-providing companies in South India offers the best quality TMT Rebars in Chennai. ARS Steel’s 550D TMT Bars have reformed the future of the steel industries by providing premium quality, better resistance in terms of climatic disasters and corrosions, and ideal structure.

Identifying your Steel

Scientifically

There are two tests that can help you identify the quality of your material; The Acid & The Magnetic Test. As the name suggests, the acid test is a scientific method that can prove the quality of your steel by using two spoons. However, both the spoon should differ in quality, one should be of a better caliber than the other. Once you have the spoons ready, add vinegar to them and leave them for a while for better distinguishing. Upon tasting, you’ll notice that the vinegar on the poor-quality spoon tastes purely like metal, while the spoon with a better caliber tastes exactly like vinegar. Thus, showing the difference between the two.

The magnetic test is another scientific method where you check the presence of nickel in the steel. If it contains nickel, then the magnet will not tend to stick to it, showing the real standards of the material. However, this test is not always reliable, but it’s worth a try.

Non-Scientifically

This test focuses on bending TMT Rebars through the process of plastic deformation. In this test, force is applied to the bar until it bends at a specific degree to determine the stability of the steel. The test is normally carried out with the help of two supports, and a mandrel in a room temperature area, while focusing on the length of the test piece, which totally depends on its diameter.

This test focuses on the effects of strain on the steel with the help of nitrogen diffusion, and that is because the risk of the material cracking is highly possible when the temperature is decreased. The test following the bending of a TMT Rebar at a 157-degree angle by applying load to it after immersing the material into boiling water for 30 minutes and then cooling it off via nitrogen.

Safety Guidelines

Being exposed to construction sites can be of high risk, and that is due to the fact that the work done there involves different processes, machinery and materials. So, it is of utmost importance that you ensure your safety before visiting such areas. This includes the other workers and engineers present there. The following factors are to be highly noted during a visit to a construction site:

• Safety shoes to keep your legs dry and warm.
• Construction helmet to protect yourself from harmful sun rays, as well as any damage that can be caused.
• Dust protective masks to avoid hazardous specks of dust from entering your lungs.
• Safety gloves to avoid direct contact with harmful objects.

They provide the certainty needed to escalate a customer’s experience, with the help of facilities like OES, and other Lab facilities required for the analysis of macro on the results. The company is known for its high-quality 550D TMT bars that have been in the market for over 4 years, offering safety against earthquakes and cost efficiency regarding construction.

TMT BARS: ARS 550D Grade

Being the backbone of construction, TMT bars cannot be compromised when it comes to quality. These bars are made metallurgically, where mechanical and thermal processes combine to form a single product while focusing on its ductility. Many buildings often break down or aren’t strong enough to face climatic disasters, and the primary reason for that is their lack of load-bearing capacity. If the ductility in a bar isn’t strong enough, then it’s obvious that it won’t be able to sustain the structure of the building long enough.

ARS 550D bars have greater strength in terms of ductility and are used for construction projects on a larger scale. They are a superior version of Fe 550 Grade TMT bars that offer greater stability and ductility, making them an ideal choice for construction. Their chemical properties consist of 0.100 S+P, 0.30 Carbon, 0.055 Sulphur, and 0.050 Phosphorous.

Benefits of ARS 550D TMT Bar’s during construction

• Lesser Consumption: Using ARS 550D TMT Bar’s reduces the consumption of steel by 12-15%, as compared to the others.
• Lower Labor Cost: Less consumption of steel will result in fewer laborers to work on a construction project, and therefore, lower the extra costs.
• Reduced Congestion: Using a stronger class of steel allows you to reduce the diameter of the bar, which then results in increased spacing and less consumption.
• Greater Savings: While congestion and consumption are reduced, the amount of steel needed in construction also decreases. Thus, resulting in money being saved.
• Quicker Construction: Since the required amount of steel to construct is lessened, cranes can work faster by carrying a definite number of bars, which also helps the construction speed to increase.

Differentiation Between Ductile & Non-Ductile Materials

A good example to understand the difference between a ductile and non-ductile material would be by observing the changes that take place when you drop a sponge and a rock from a good height. The sponge remains intact even when it has gone through a stressful situation, whereas the rock tended to break and lessen its natural properties. Similarly, a perfect TMT ductile bar will have its properties unscathed whether or not it is going through a forceful phase.
