The selection of the appropriate grade of the TMT bar is a crucial step in the construction of your dream project, work with your architect and engineer to look for and choose the bar best suited to your design requirements.

The Bureau of Indian Standards (BIS) has provided a wide range of grades to help you make your choice. Each grade of the TMT bar has its own individual use and application, and while there is significant overlap, the devil is in the details.

The stress should be on selecting a TMT bar best suited to your project design, and not on cost of the bar or grade.

SUMANGALA 550D

The Sumangala Fe550D series of TMT grade bars are ideal for high-rise structures and buildings that are expected to bear heavy footfall, like malls, hospitals, flyovers, etc. or for regions prone to seismic volatility. The percentage elongation is higher in these bars as they will face higher tensile stress and/or thermal variation.

SUMANGALA 550

The sacrifice of ductility in favour of greater yield and tensile strength, along with a stress on corrosion resistance makes the Fe550 ideal for use in coastal, humid and other geologically stable regions. These bars are also a viable choice for construction of underground structures.
