In the previous blog we broadly discussed the subtle differences between FE415 and FE500, in this blog we will discuss some details about the real world implications when using FE415 and FE500 TMT bars. Let’s first discuss the needs and demands of an average homeowner strength, aesthetics, reliability, longevity and again strength.
TMT Bars for Aesthetics
When it comes to aesthetics, FE415 is the clear winner as this TMT bar have better bendability that FE500. It’s not that FE500 TMT bars cannot be bent, but it takes specialised equipment to do so. This is somewhat an expensive exercise, but the real problem lies in the fact that due the strength of FE500, while bending the protective coating can get torn off. This torn off coating protects the TMT bars from rust and corrosion, using rusted TMT bars can severely reduce the strength of the TMT bars. FE415 have better bendability making them perfect of structures with circular elements of a structure.
TMT Bars for Strength
When it comes to strength, FE500 is stronger than Fe415. But the strength of FE500 is bit much when it comes to building homes, FE415 is a better choice as it is cheaper and can withstand earthquakes of considerable magnitudes as well. FE500 is not suited to structures built along the earthquake prone areas of India. Another issue that comes with FE500 is weldability, it can be done but when compared with FE415. It is an expensive process and the danger of rust and corrosion also looms if the welding process is not done properly. Welding can also reduce the overall strength of TMT bars. Try to avoid welding TMT bars as much as possible, it doesn’t what the grade is.
