The unique rib pattern of RATHI SHAKTIMAN Steel Bars is not only uniform but also solid and provides unparalleled bond strength between the bar and the surrounding concrete. RATHI SHAKTIMAN Steel Bars conform to the stipulations of IS: 1786 and international standards.

The higher tensile strength of RATHI SHAKTIMAN Steel Bars enables reduction in quantity of steel required in civil projects. RATHI SHAKTIMAN Steel Bars have exceptional dimensional tolerance and are rolled on the negative side of the Indian Standards Code, resulting in lower steel consumption.

With their tough outer surface and soft core, RATHI SHAKTIMAN Steel Bars have excellent bendability, which makes the work at construction sites easy and safe. RATHI SHAKTIMAN Steel Bars can be bent around mandrels much smaller in diameter than those specified in IS: 1786..

Due to controlled quantity of Carbon and Manganese, RATHI SHAKTIMAN Steel Bars derive excellent welability. There is no loss of strength at weld joints. This ensures that they can be butt-welded or lap-welded without any requirement for pre or post welding treatment.

RATHI SHAKTIMAN Steel Bars are a perfect combination of strength and ductility. Elongation in RATHI SHAKTIMAN Steel Bars is a measure of ductility, and the very fact that RATHI SHAKTIMAN Steel Bars attain elongation of up to 22%, says it all.


Manfacturing Process

Unique Production Process by Hot Charging

Using the world's best technology, RATHI SHAKTIMAN Steel Bars draw their strength from computer controlled in-line process of hardening & tempering using hot rolling (TMT). After leaving the last rolling stand at the required temperature, the hot rolled bar passes through a set of specially designed cooling pipes. The outer layer gets cooled while the core is still hot. The surface of the bar gets self-tempered by the heat from the core. The combination of a tempered martensite surface and ferrite + fine pearlite core provides considerably higher strength and ductility to the finished material, making it ideally suited for building strong structures

We use the unique hot rolling process of production in which we use the best quality MS Sheet Cutting to produce inhouse high quality chemically tested billets, which are directly hot rolled into the rolling mills this being a unique facility only with Rathi in the whole of Northern India


Every step in the operation of the Thermomechanical (TMT) process as been scientifically engineered to ensue perfection to the core. From monitoring the chemistry of raw material, diameter of the bar and speed of rolling to calculating the quantity, pressure and temperature of water to attain the optimum physical parameters every time.
