The thing is that your TMT bar is the very framework on which your house would be standing, so it would be better if you could get an idea of the varieties of the TMT bars. The Top Quality TMT bars have a set of specified features that fit your demands. In this article, we discuss the composition of the various grades of the TMT bars that would play an umpteen role in keeping your dream construction safe and secured. So stay tuned and keep reading.
The thing is that the Best Quality TMT bars possess the umpteen qualities to keep your construction safe and secure. However, do you think that all the categories of the TMT bars come with an equal volume of strength? Not!! There are different grades with each of them possessing different strengths in terms of corrosion resistance and ductility, getting suited for different purposes. The primary differentiating factor that causes the differences in properties is the difference in grades. In the following points we would be discussing the various grades and composition of the TMT bars.
1. Fe 415 Grade
Fe 415 grade TMT bars contain Carbon-0.30%, Sulphur- 0.06%, Phosphorous-0.06% and S+P-0.110%. These properties give Fe 415 grade bars a yield strength ranging between 415 N/sq.mm. As far as elongation it ranges anywhere between 415 N/sq.mm and 485N/sq.mm. As far as elongation is concerned, these bars give you an elongation of up to 14.5%. With this chemical composition and its properties, Fe 415 grade bars are ideal for small-scale construction like houses and residential apartments.
2. Fe 500 Grade
Fe 500 Grade also contains Carbon at 0.30%. However, in this grade, Sulphur composition stands at 0.055% and Phosphorous at 0.055%. The S+P composition stands at 0.105%. With these properties, you get yield strength in the range of 500 N/Sq.mm and 545N/sq.mm, which is superior to Fe 415 grade. Hence, these bars are suitable for higher-end constructions like high-rise buildings, multi-story apartments, stadiums, bridges, etc.
3. Fe 550 Grade
As far as Fe 550 grade steel bars are concerned, the composition comprises 0.30% Carbon, 0.055% Sulphur, 0.050% Phosphorous, and 0.100 S+P. This gives an even higher ductile strength of up to 585N/sq.mm, which is one of the highest for any grade of TMT Bars. At the same time, the bars have an elongation as high as 10%.
4. Fe 600 Grade
Fe 600 grade is the highest grade of TMT bars which offer the highest strength. Its composition comprises 0.30% Carbon, 0.04% Sulphur, 0.04% Phosphorous, and 0.075% S+P, and offers a tensile strength of up to 660 N/sq.mm. Such high-strength TMT bars are not generally used for regular construction projects but are the best for projects which require extraordinary strength and characteristics.
Choose the Best TMT bars per your needs, and stay secured for a lifetime.
