TMT Steel Bars
Description:
Argee Steel Inc
has expertise in manufacturing of world class Construction TMT Bars used in diversified construction requirements. Our manufactured Thermo Mechanically Treated Steel Bars exhibit high bendability and re-bendability features due to due to lower carbon content and higher elongation. Excellent yield and ductility characteristics of our Building TMT Steel Bars make them perfect to use at earthquake zones. Argee Steel TMT Bars are made at our state-of-the-art plant and under the close supervision of frontline engineers and metallurgists.
The Construction TMT Bars are passed through a highly controlled in-line process of hardening and tempering during hot rolling. Prior to passing through the finishing stand, Ribbed Bars undergo specially designed water-based cooling systems. The cooling system transforms the outer surface to marten site, while the core remains comparatively hot and austenitic. The composite structure has so formed high yield strength and excellent ductility characteristics.

Features
Excellent Bond Strength
: The rib pattern of TMT Bars has been specially designed to ensure excellent bounding between the bar and the surrounding concrete. These 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
: TMT Bar has 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 retile coated electrodes of matching strength.
Super Bend Ability
: The tough outer surface and the ductile core of I TMT Bars make it extra high ductile and bendable than reinforcement Steel Bars.
Highly Resistant Against Corrosion
: Our premium product TMT is manufactured by thermo mechanical treatment processes with no tensional residual stresses on the Bars. This results in superior corrosion resistance characteristics than conventional Bars.
Dimensional Tolerances
: Argee Bar confirms to the IS: 1786 standard laid for dimensional tolerances and has section weight generally lower than found on other bars.
More Economical
: Argee manufactured TMT Bars are new generation high strength bars with usable yield strengths in excess than required to meet Fe-415 grade and ARE - 1786 standard. It helps our Argee 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.
