Structural integrity is a significant aspect of the 21st-century construction domain. That’s where the need for high-quality steel bars comes in. However, regular steel bars are susceptible to rust and corrosion. They might weaken the structure after a few years. So, the construction domain has shifted its focus to a more reliable and sustainable solution. This is where the role of TMT bars comes into being.
Technically, it’s known as thermo mechanically treated bars that have become a significant element in this construction domain. However, with so many manufacturers competing against one another in India, finding reliable bars might be a challenging process. That’s why this post narrates the tips to select the right TMT bars.
5 Things to Keep in Mind When Selecting the Right TMT Bars
Due to its strength and durability, TMT bars have become an extremely important construction material. However, someone new to this industry may become utterly confused by checking multiple manufacturers selling the same type of bars. So, if you are a beginner who knows nothing about selecting TMT bars, here’s simplifying your job. Before consulting the TMT steel bars wholesale dealers, let’s check out the five practical tips.
Importance of Quality Testing
Noteworthy to state, various TMT bar manufacturers operate in a land like India. But do you think everyone delivers premium-quality bars? The answer is a simple no. A customer should always focus on comparing different manufacturers. The best way to start this survey is by conducting quality testing. You can conduct the tests to assess the bars’ bendability, strength, and durability.
You should always remember that after every test, the bars should return to their previous state. That means it should be strong from the outside and soft from the inside. That makes these bars incredibly significant for construction purposes, regardless of the type.
Types of Manufacturing
A TMT bar’s manufacturing process determines the overall standards. The manufacturing procedure includes these things:
● Rolling
● Water quenching
● Heat treatment
● Cooling (various stages involved)
With these processes, the TMT bar becomes highly durable and flexible. As a construction company or professional, your job is to ensure premium quality bars. Bars that are produced using premium quality methods ensure minimum impurities and improved strength.
Which Grade You Need for the Construction Project
TMT bars are available in India in various grades like the following:
● Fe 415
● Fe 500
● Fe 550
● Fe 600
A bar with a higher grade ensures more strength. That means the highest one (i.e., Fe 600) is used for industrial or civil projects. The lower ones are used for smaller constructions. You can choose a bar based on the type of construction.
Adaptability
A TMT bar should be flexible and durable to offer the construction project the kind of structural strength it requires to be durable for years. That’s why you also need to ensure adaptability as a prime aspect to consider while selecting the TMT bar for your project. Remember, a bar that breaks easily would never support the house’s strength. In addition, it may also not resist natural disasters like earthquakes or storms.
Corrosion or Rust Resistance
The TMT bars should be able to support a building’s weight and its entire structure. Thus, a construction company should only work with durable TMT bars. You may conduct the atmospheric exposure testing. It is also referred to as a weathering test. Here, the durability of the bars is examined by exposing them to cyclic cooling or heating and UV light.
Besides, some standard tests are there that can measure the corrosion resistance of these TMT bars. Note that TMT Sariya is the best material that ensures the construction’s overall stability over the years.
What are the Raw Materials Used in the TMT Bar Manufacturing?
The following are the raw materials used for manufacturing TMT bars:
Iron Ore
It is a mineral substance heated to produce metallic iron. It’s used for extracting metallic iron. After it is extracted from mines, iron ore undergoes several methods to transform into steel. It offers the core strength to the TMT bars.
Dolomite and Limestone
These are sedimentary rocks. While dolomite has a higher content of magnesium, limestone comes with a higher content of calcium carbonate. Basically, dolomite is a mixture of calcium and magnesium carbonate.
Both these materials are the fluxes used in the TMT manufacturing process. They act as refractory materials that react with unwanted elements such as alumina and silica. So, they create slag and separate impurities from molten iron. They are responsible for making the TMT bars purer.
Coke and Coal
Next are the most important materials – coke and coal. These elements come from fossil fuels and are derived from various materials.
Other Raw Materials Used
Other materials are the alloying elements that are responsible for increasing the cast iron’s strength. A few common alloy elements used in the process are:
● Manganese
● Copper
● Vanadium
● Nickel
● Molybdenum
● Chromium
The above raw materials are used to refine the bars’ properties. Ian is also used in the refinement process. Supplementary materials used in the manufacturing process include boron, calcium carbide, or ferroalloys to improve the quality of the TMT bars further.
Additional Tips to Choose a Reliable TMT Bar Company
The most effective way to identify the best TMT bar company is by checking their certifications. Whenever you search for a trustworthy TMT bar manufacturer, always ensure the company has the ISO 9001:2015 certification. Pricing is another important aspect that you need to consider. You may compare three or four TMT bar suppliers’ pricing with the above certification to ensure quality products at affordable prices.
You also need to evaluate the company’s reputation. You may check the manufacturer’s official website and customer reviews before selecting the TMT bars. Remember that quality TMT bars will keep your constructed structure durable for decades. So, to ensure customer satisfaction and safety, you should keep the above things in mind before selecting these bars.
