TMT steel bars are available in various grades such as Fe-415, Fe-500, Fe-550, and Fe-600, each indicating different levels of tensile strength measured in megapascals (MPa). Fe-415 is commonly used in general construction, while Fe-500 and higher grades are suitable for structures requiring higher load-bearing capacity, such as bridges and high-rise buildings. Fe-600 offers the highe... https://bit.ly/3xtYW15
