Generating Powerful Product
From making huts by hand to today, creating bigger structures using modern tools, construction can be said to represent one of many of our civilizations’ biggest achievements with Thermo Mechanical Treatment (TMT) Bars as one of the biggest and revolutionary contributors to fast-tracking the dream structures in recent times. TMT Bars have become an integral part of the construction material as they are lighter, yet stronger, in giving support to larger surfaces. The TMT Bars have truly empowered the momentum in the world of construction.
Processing
Thermo Mechanically Treated (TMT) bar is one of the most common reinforcing bars used in the construction of homes, multi-story buildings, bridges, flyovers, and other civil engineering projects. It is renowned for its superior tensile strength, ductility, and longevity. TMT bars are the most secure solution for building because of their high level of seismic resistance. Thermo Mechanical Treatment is the name of the procedure used to create TMT bars. An essential input in this procedure is iron scrap. The iron scrap is melted in an electric furnace and then shaped into rectangular billets using a casting machine. To get the appropriate size and form, these Billets are now subjected to different rolling and polishing procedures above the recrystallization temperature. Hot rolling is the name of this procedure.
Producing Quality with Strength
The letter Fe stands for iron in TMT bar grade Fe 500, while the number 500 represents its minimum yield strength in N/mm2. This type of TMT bar is corrosion-resistant and ideally suited for the construction of multi-story and commercial structures.
Mechanical characteristics of Fe 500 TMT bar:
They have a
-500N/mm2 yield strength
-545N/mm2 ultimate tensile strength
-12 elongation
-1.09 YS ratio.
The number "500" in the Fe 500 & FE 500D TMT Bar denotes the minimum yield stress in MPa. Compared to other grades of TMT Bar, FE 500D has a higher percentage of elongation.
The top TMT Bar should be able to resist corrosion, absorb excess energy during earthquakes, and protect buildings from fire.
The top TMT Bar should be able to resist corrosion, absorb excess energy during earthquakes, and protect buildings from fire.
It contains the amount of 0.25% of carbon, 0.04% of sulfur, 0.04% of phosphorus,
0.075% of sulphur+ phosphorus.
In the TMT bar grade Fe 550D, the letters Fe stand for manufactured of iron, the number 550 represents their minimum yield strength in N/mm2, and the letter D represents greater bar ductility. The largest industrial building projects are the greatest candidates for this grade of TMT bar. It works best when used in an earthquake-prone location.
The yield strength (FY) of TMT bar grade Fe550D is 550N/mm2, while the ultimate tensile strength (fu) is 585N/mm2, and the elongation is 16.
The construction of huge subterranean structures and large-scale projects like bridges are best suited for this grade of TMT bar. They have yield strength of 550 N/mm2, an ultimate tensile strength of 585 N/mm2, an elongation of 10, a YS ratio of 1, and a tensile strength ratio.

Depending on the style of the construction, picking the appropriate grade is crucial. The designer chooses the suitable grade of TMT bar during the structural design of the construction based on material availability and economic factors. The most used TMT bar/steel grades are Fe500, Fe 500D, Fe550, and Fe550D which offer enough strength for the majority of reinforced concrete applications.
According to IS:1786 requirements, maXXon TMT Fe-500, 500D, & fe550, 550D are manufactured entirely of billets, and their chemical compositions of carbon, sulfur, and phosphorous are tightly under control. Our TMT bars and the concrete that surrounds them form an unbreakable link. Our TMT Bars’ unique rib layout is to blame for this. Our TMT bar is flexible and perfect for construction because of its soft core and robust outer surface. According to IS: 1786 specifications, bending around significantly smaller mandrels is a distinct benefit on construction sites. Our bars are better weldable due to their reduced carbon content. Manual arc welding does not require pre-warming or post-welding. Our product comes with a section weight that is lower than average and is guaranteed not to be hefty. Our TMT bars have a soft ferrite-pearlite core that allows them to withstand seismic and dynamic loads. Our TMT Bar’s strength and ductility are more than the minimum values stipulated by IS:1786. Superior strength and ductility ratings signify a better level of safety.
MECHANICAL PROPERTIES
A combination of strength and ductility produced by maXXon TMT Bar’s distinctive manufacturing procedures exceeds the minimum limit stipulated in the standard IS: 1786 certification. Although the standard calls for minimum yield strength of 500 N/mm2 for Fe500 grade, we manufacture at a minimum of 540 N/mm2. Additionally, our product’s normal ductility value, as determined by elongation, is 18 percent minimum, as opposed to the industry standard of 12 percent. As a result, our goods have outstanding strength and ductility properties. The ability to withstand the pressure of an earthquake is reflected by the UTS/YS ratio and percentage of elongation.
