Why Are FE 500 and FE 500D The Most Preferred TMT Bars

If you are using TMT bars in your construction, then one of the most important things to keep in mind while choosing the right TMT bars is their grade. TMT bars are of different grades - Fe-415, Fe-415D, Fe-500, Fe-500D, Fe-550, and Fe-600. In these names, ‘Fe’ represents iron and the number represents the yield strength of steel. ‘D’ stands for ductility. Thus, different kinds of TMT bars have different chemical compositions which leads to differences in their tensile strength, yield strength, thermal conductivity, ductility and durability. Among all these grades, Fe-500 and Fe-500D are the most preferred grades for TMT bars in civil construction.

Chemical Composition and Mechanical Properties

The chemical composition and mechanical properties of both Fe-500 and Fe-500D TMT bars are conducive to strong and reliable construction, which makes them a market standard in civil construction.

Advantages of Fe-500 TMT Bars

With 18% elongation, Fe500 TMT bars are highly ductile

With 520 N/mm2 of yield strength, Fe500 TMT bars have a high level of strength. Their physical and chemical properties make them suitable for construction of houses.

They can bear seismic and dynamic loading effectively which makes them suitable for construction in earthquake zones 3, 4 and 5.

The carbon content in Fe500 TMT bars is optimal and makes them highly resistant to corrosion.

If they are built using Ladle Refining Furnace (LRF) technology, then they are devoid of impurities like sulphur and phosphorous and harmful gases like oxygen, hydrogen and nitrogen.

They contribute to making the building fire-resistant.

Advantages of Fe-500D TMT Bars

Fe500D TMT bars are highly ductile with a minimum of 18% elongation. In fact, they are most ductile among all grades of TMT bars.

With 520 N/mm2 of yield strength, Fe500D TMT bars have a high level of strength.Their physical and chemical properties make them suitable for construction of large-scale projects like airports, multiplexes, flyovers, malls, etc.

They have exhibited good performance in seismic and dynamic loading which makes them suitable for use in construction in earthquake zones 3, 4 and 5.

They are highly resistant to corrosion as they have the optimum carbon content.

They help in increasing the fire-resistance of structures.

If they are built using Ladle Refining Furnace (LRF) technology, then they are devoid of impurities like sulphur and phosphorous and harmful gases like oxygen, hydrogen and nitrogen.
