It is very difficult to choose one from so many brands and grades available in the market. Because many low quality bars are also sold in the market, which is important to avoid.
Here are some important tips, keeping in mind that you can choose the best bar.
1. Availability and Rates
The most important thing is availability and rates. Make a list of 3 to 5 rebar brands by rate from among the bar brands you find in your area.
2. Certifications
Then the next most important point is that the bar brand you choose should be certified by BIS standard IS 1786: 2008 and ISO standard. Certifications signify a high standard of quality and protection.
You can see it on the TMT rebar packet or directly ask the shopkeeper or you can check it on the website of that TMT rebar company. You may also visit www.bis.gov.in and www.iso.gov.in for satisfaction.
3. Grade
The durability of a TMT bar is determined by its grade. The order of selection for the grade of TMT bars will be as follows.
Fe 550SD, Fe 550D, Fe 500D, Fe 550, Fe 500, Fe 415D, Fe415.
You should prefer Fe 550D grade or Fe 500D grade of TMT bar (Sariya) as your first choice. Their SD grade or CRS Fe 550 grade would be even better if they were available. Here CRS stands for Corrosion Resistance Steel.
4. Corrosion Resistance
If you are constructing your building in water prone areas then it is better to use CRS grade of TMT rods.
5. Earthquake Resistance
If you are constructing your building in earthquake prone areas you should use Fe 550SD or Fe 550D grade of TMT rebar.
6. Length and Weight
The length and weight of the TMT bars must be similar as standard. Each TMT bar is of length of 12 Meter or 40 feet. But each size TMT bar has different unit weight.
7. Manufacturing Techniques
High quality TMT steel bars are manufactured using virgin iron ore and pure steel with latest technology. You can learn the technique of making that bar on the website of the baria company. HYQST and LRF technology is currently in vogue.
8. Size
The size of TMT bars must fulfill the construction structure’s requirements. Because of different construction applications require different sizes of TMT bars and also various construction sites have different requirements.
Some Characters of the Best Quality TMT Bars
Here are some of the important characters of excellent quality bars.
Uniform Rib Pattern:
The rib pattern on the TMT bar should be uniform. In poor quality bars, the pattern does not remain the same. This uniform rib pattern is what allows the bar to bond well to the concrete.
Earthquake Resistant:
TMT bars protect your home from natural calamities like earthquakes. Fe 550SD or Fe 550D grade bars are ideal for earthquake-prone areas.
Corrosion-Resistant:
The TMT bars must be corrosion resistant. When the bar gets rusted, it weakens the concrete structure. Almost all good quality TMT bars are resistant to corrosion. However, if you are building your project in an area with high rainfall or in an area prone to waterlogging, you should use Fe 550 of Fe 500 grade rebar with high CRS.
High level of weldability:
Higher quality bars have higher weldability. And they lose their properties to a very small extent at the welding site.
High degree of ductility:
Ductility is a very important quality of rebar. This ductility is what makes the bar earthquake resistant. It is denoted by D in the grade of TMT bar.
High level of bendability:
The higher the bendability of the bar, the more easily it can be bent.
The amount of carbon, sulfur and phosphorus in the bar:
The maximum amount of carbon, sulfur and phosphorus in the bar should be as shown below. They live in the form of impurity in the water. That is, their quantity in the bar should not be more than the table given below.
The TMT bar you choose must have the above qualities. You can see them on the website of the company of TMT brand. You can check the quality of the TMT bars by getting it tested in a lab.

Tata Steel Limited, JSW Steel Limited, Steel Authority of India Limited (SAIL), Jindal Steel & Power Limited, Rashtriya Ispat Nigam Limited, ESSAR Steel India Limited, JYOTI TMT, Radha Smelters Private Limited, Sree Metallics, SRMB Srijan Pvt Ltd, Shyam Steel Industries Limited, Kamdhenu Limited and VISA Steel Limited are some of the bars manufacturers you can trust for high quality bars.
