TMT Bars

Our Thermo Mechanically Treated TMT steel bars are widely used in all types of construction purposes. They exhibit very high bend ability and also re-bend ability features due to lower carbon content and higher elongation with excellent yield and diuctility characteristics, our TMT steel bars are ideally suited for application in earthquake zones.

Process
These bars are manufactured at our state-of-the-art plant located in bhiwadi in rajasthan, under the close supervision of frontline engineers and metallurgists. Our extensive experience in rolling has empowered us with the capability to develop TMT steel bars of teh highest quality. The bars through a highly controlled in-line process of hardening and tempering during hot rolling. Once passing through the finishing stand, ribbed bars are passed through specially designed water-based cooling systems. The co#21ADF6oling system transforms the outer surface to martensite, while the core remains comparitively hot and austentic. The composite structure so formed high yield strength and excellent ductility characteristics.

Some of the salient features of our Trimurti - TMT steel bars are -

  • Excellent Bond Strength:
    The rib pattern of Trimurti - TMT bars has been specially designed to ensure excellent bounding between the bar and the surrounding concrete. The ribs are uniform and concrete due to cutting by automated machines. Thus the bond strength is 100-200% higher than the M.S plain bars and convectional CTD bars.

  • Excellent Weld Ability:
    Trimurti bar has a far more superior weld ability than convectional CTD bars. Due to its low carbon content, it can be butt- welded or lap - welded using ordinary rutile coated electrodes of matching strength.

  • Super Bend Ability:
    The tough outer surface and the ductile core of Trimurti TMT bars makes it extra high ductile and bendable as compared to reinforcement steel bars.

  • Highly Resistant Against Corrosion:
    Our premium product Trimurti -TMT is manufactured by thermo mechanical treatment processes with no torsional residual stresses on the bars. This results in superior corrosion resistance characteristics than conventional bars.

  • Dimensional Tolerances:
    Our bar confirms to the IS : 1786 standard laid for dimensional tolerances, and has section weight generally lower than found on other bars.

  • More Economical:
    Our TMT bars are new generation high strength bars, with usable yield strengths in excess than required to meet Fe-415 grade and IS:1786 standard. It helps our bars take higher stress levels, resulting in less consumption of our steel bars than other conventional bars. Thus it helps in saving the valuable money of our clients and avoiding unnecessary loads on the structure.

HSD Bars

We offer to our clients premium quality 'High Strength Deformed Steel Bars'. We use modern machinery and infrastructural facilities, with premium grade raw materials in the production processes. Our quality control processes ensure that the mechanical quality of the product is manufactured in a consistent precision based atmosphere. It also helps us in meeting dimensional tolerance and surface quality requirements as per the international standards.

Some of the salient features of our HSD bars are -

Lower Carbon Value:
Our product feature lower carbon level, resulting in good ductility, strength and weld-ability.

Dimensional Tolerances:
We offer excellent dimensional tolerances as per the specifications.

Superior Bond Strength:
Our HSD bars are well known to have excellent bond strengths, when used with concrete.

Welding Capability:
As our bars have lower carbon content, it has better welding capability than conventional bars.

High Tensile Strength:
Our bars feature high tensile strength. It is a great asset in construction process, where a lot of bending and re-bending is required.

Wide Application Range:
Our premium quality product has a wide application range like in building residential, commercial and industrial structures, bridges, etc.

The Quality & Dependability Symbol:
All the products manufactured by us come with a hologram, with our name and type of product written on it. Our customers does not take it just as a hologram, but as a seal of quality, durability and dependability.

CTD Bars

CTD Bars

Our CTD steel bars are both economic and efficient, and is suitable for all reinforced concrete constructions. Our product is widely used in buildings, reservoirs, power structures, etc.

The salient features of our CTD steel bars are -
  • Greater yield and bond strength.
  • Good bend ability and weld ability.
  • Lesser cracks.
  • Better safety features due to hyper resistance.
  • They are suitable for both compression and tension reinforcement.

Product Chemical Composition:
Trimurti TMT bars are produced in Fe 415, Fe 500 & Fe 550 grade. As carbon levels are restricted to much lower than the requisite specifications, it results in excellent ductility high bend ability and superior weld ability. The chemical composition of our product is as under:


Chemicals Unit IS: 1786-(Fe 415) Trimurti – TMT
Carbon % 0.30 max. 0.17-0.24
Sulphur % 0.060 max. 0.060 max.
Phosphorus % 0.60 max. 0.055 max.
S & P % 0.110 max. 100 max
