Using TMT bars of Fe-500 grade instead of Fe-415 grade leads to up to 20% savings on material thus leading to a saving in the amount spent on buying TMT bars. The difference in the strength between Fe-415 and Fe-500 grades is 20%, Fe-500 being 20% stronger than Fe-415. The reason for this is as follows:
– Fe-415 denotes that a force of 415 N/sq.mm. is required to deform the TMT bar, whereas Fe-500 denotes that a force of 500 N/sq.mm is required to deform the TMT bar.
– The difference in the strength between Fe-415 and Fe-500 grades therefore is 20%.
This gives Fe-500 a superior structural strength than Fe-415 and therefore lesser number of Fe-500 TMT bars are required to hold the structure as compared to Fe-415.
For instance, if a structure requires 1 ton of steel, which costs Rs 50,000 for Fe-415, then Fe-500 grade would require, 0.8 ton of steel, which would cost Rs 40,000 leading to a saving of Rs 10,000 per ton. Unlike other brands which claim to manufacture Fe-500 while actually manufacturing Fe-415, Moira guarantees it’s Fe-500 grade TMT bars are 100% genuine.
