Benefits of Shivangi TMT Bar

Use of Billet

The use of billet which is a superior semi finish than ingot used by traditional mills reduces slag inclusions, gases and piping as compared to Ingot which are harmful for TMT bar.

Fe500 & Higher Strength

Controlled chemistry, added alloys to strengthen and modern process is used to produce the desired grade. Tested and guaranteed Fe 500 grade ensures safety and helps saves cost because less steel is consumed in this grade

Ductility & Easy Bends

Because of the TMT process, the soft inner layer gives the rebar a bend ability and hence provides better ductility. Also, using processed iron ore in melting, brittle elements like sulphur and phosphorous are reduced and silicon & manganese are added which makes the rebar even more ductile. This can be verified through elongation test.

Low Tramp Elements

Minimum tramp elements both ferrous and non-ferrous are minimum due to the use of processed iron ore for producing clean steel.


Superior weld-ability attained because carbon is in the ideal range. Also because the brittle sulphur and phosphorous are under control, tendency of weld to crack is little.

Yield Stress & UTS & Elongation

Better than standards due to lower tramp elements and controlled chemistry of melt. Also due to ideal inner and outer ring in the tmt bar, the bar is ductile as well as strong. Therefore, elongation is 18% which is ideal for fe500 grade.

Uniform ribs & lugs

The focus during the rolling process provides a better reinforcement grip.

Corrosion Resistance

In the TMT process, no twisting of the rebar takes place. This increases the corrosion resistance as compared to the CTD(Cold twisted) bars.

Fire Resistance

SHIVANGI TMT BARS have high thermal stability and can counter temperature up to 400 to 600 degree Celsius

Earthquake Resistant

The TMT bars produced have typical elongation between 16-25%, well above the minimum 14.5% in BIS standards. Elongation helps to absorb earthquakes.

Cost Effective

Using SHIVANGI TMT Fe 500+ re-bars instead of Fe 415, can save up to 17 – 18% per quintal in the total cost of construction.
