If you are researching about TMT Bars it is most likely that you are looking to lay the foundation of your home, or are going to undertake a building project. Doing something as significant as either of the two is a herculean task, which means that the pressure of choosing the right thing every time falls upon you. In the case of TMT bars, there are a few factors you must keep in mind before making a choice to ensure that you choose exactly what suits you.
• Grade of the bar
The grade of a TMT bar is a measure of how strong it is, and the higher the number, the stronger the bar. The different grades range from Fe-415, Fe-500, Fe-550, to Fe-600, with varying strengths. Bars with a higher grade are more suitable for the core of your building. They are also used when their function matters more than the form, and in large structures such as airports and harbours. Lower grade bars are more useful in constructing decorative structures and things like balcony railings.
• Ability to bend
Bars that are higher on strength do not fare too well when it comes to flexibility, and they are not ideal to build aesthetic structures. Even then, make sure that the bars you invest in do not develop cracks under stress. This is especially important for earthquake resistance.
• Ability to elongate
Another aspect to enquire about is the extent to which bars can elongate. This is also known as ductility and is important since bars that can elongate can withstand natural calamities better. The better the bars are at elongating, the more you can save on construction, and they are also cheaper to transport. Besides, these bars also offer more longevity.
• Resistance to corrosion
This quality is very important to consider, since TMT bars will come into contact with moisture frequently. Without corrosion resistance, they will not be durable. It is important to ensure that they have been coated with water-resistant material.
Lastly, you must check for yourself whether the bar has the seal of the manufacturer, such as Jindal TMT on it. This will help you purchase only the best and the most reliable quality bars.
Do not settle for cheap bars and make sure that your investment is worth it. These bars determine whether the structure of the building will last for long or not. Before taking a decision, research more about which kind of bars will suit which part of your construction, and plan accordingly keeping your budget constraints in mind.
