Concrete buildings and structures heavily rely on the thermo-mechanically treated bars, or TMT saria. These rods are specially formed to provide support to the concrete structures. It is made by heating the bars at a specific temperature and rapidly cooling them by quenching. That is why it is called a thermo-mechanically treated bar. We at Rana Max Steel make these bars to be used in construction projects of buildings, dams, flyovers, airports, auditoriums, etc. By providing them in robust quality for excellent performance, we have earned our reputation as one of the best TMT saria bars Distributor. We are sharing our expertise as top manufacturers to tell you what the key technical factors are to assess the TMT saria.
Key Technical Aspects of TMT Saria Bars
There are many technical aspects associated with these bars. These are divided into various grades, and each grade has many features that need to be known when choosing the best TMT saria bars Distributor. Here are those aspects in broad terms:
Chemical Composition
TMT bars use iron as a base metal in which carbon, sulphur, phosphorus and traces of corrosion-resistant elements are added. The percentage of these compositions decides the grade of bars.
Grade
The grades of TMT bars are denoted by Fe, followed by a number. The higher the number, the stronger the tensile strength. These grades are decided by Indian Standards (IS:1786), American Standards (ASTM A 615), and European Standards (DIN 488) in different compositions.
Tensile Strength
The tensile strength is different for different grades and standards. For example, the tensile strength of Fe 415 as per the Indian Standard is 485 N/mm2, while for the European Standard it is 500 N/mm2.
Elongation
The elongation is the maximum amount of stretching before the TMT bar breaks. It is expressed in percentage. The bars by Rana Max Steel can elongate up to 17, 15 and 10% for Fe 415, Fe 500 and Fe 550 respectively.
Bend Test
In testing the bars for bending, a mandrel is used that with sizes larger than the nominal diameter of the TMT bars. Being the best TMT saria bars Distributor, our product has 4D and 5D rating, which means it can bend 4 or 5 times before breaking.
Final Words
To analyze the best TMT Saria Bars Distributor, you must first understand which grade of bar is suitable for your construction project. The low traffic and less load facing structures can do with Fe 415, while the heavy structures like flyovers need Fe 550 because it has better strength. At Rana Max Steel, we provide them in different grades and each of our variants has higher value than the standard ratings.
