When it comes to constructing a building structure, the right set of resources must be used for ensuring the overall life and the integrity of the building. The introduction of reinforcement in construction improved the overall life expectancy of the structure and made them strong enough to withstand the forces of nature. Steel is the primary component used as reinforcement because of its excellent tensile strength, recyclability and similar thermal coefficient of expansion to that of concrete.
This is two of the most used TMT bars when it comes to building homes in India and the average homeowners have a tough time getting their heads around to knowing their difference. So let’s begin with basics itself. Fe stands for Iron, the numbers 500 and 415 is their tensile strength and the ”D” stands for ductility. Here the word signifies the extra ductility which is generally not found in Fe 500. So why would steel companies go to the trouble of making a new grade of TMT bars instead of just promoting Fe 415? In this blog, we will try to find an answer for this conundrum.
First things first, these TMT bars are completely different due to the differences in their manufacturing process. It is where they are used is where the confusion arises. Fe 415 is a fan favourite among the average homeowner and Fe 500 is the choice for home contractors, this is mainly due to their combination of strength and ductility. Fe 500D seems to solve the problem of choosing between either strength or ductility. Fe 500 is perfect medium and small-sized commercial buildings as well as homes, and the Fe 500D can be used to construct both them, the versatility gives the Fe 500D an advantage of over Fe 500 but not over Fe 415.
Fe 415 is naturally more ductile than Fe 500D, while Fe 500D may seem like a combination of strength and ductility, it actually compromises between them. With Fe 415 homeowners get more ductility which can withstand earthquakes and other natural disasters. Fe 415 with its superior ductility can be made into shapes such as columns, slabs and other shapes. Fe 415 can be easily bent without needing the use for any bar bending and bar cutting machines as well. This significantly reduces the cost associated with building a home.
