TMT Bars – Thermo Mechanically Treated Bars are made of a newer variety of steel solely used for construction purpose. Having varied advantages over the conventional TOR steel, TMT Bars are superior in:

Bendability
TMT Bars have lower carbon content and higher elongation which makes them bendable as well as re-bendable. With internal diameters of 1D and 4D, TMT Bars can withstand bending & re-bending respectively. (D = Diameter). This feature helps in working with TMT Bars.

Weldability
TMT Bars do not loose strength at welded points and hence can be easily welded. The process of welding TMT Bars doesn't require pre-heating or post-heating as well. Pre-welded meshes can be used for construction avoiding time consuming manual bindings due to this good weldability feature.

Resistance from Rust & Corrosion
TOR steel when used in the concrete of any structure corrodes over a period of time because of the chloride ions. This results in the failure of TOR steel in most concrete structure building. Due to its thermo mechanical treatment, TMT Bars are highly rust and corrosion resistant and hence are best suited in humid as well as coastal states too.

Fire Resistance
The presence of tempered martensitic layer in the outer surface of TMT Bars, helps them retain significant strength at extremely high temperatures. This makes TMT Bars comparatively safe in case of fire hazards where temperature rises up to 600º C.

Affordable
It is evidently encountered that higher the yield strength, lower will be the support required leading to low cost of construction. Therefore, TMT Bars are affordable and save steel up 20% being technically superior having higher tensile strength than the usual TOR steel.

Usage
Several engineering properties of TMT Bars make them much more superior than the usual TOR steel. Hence these TMT Bars can be used for a variety of purposes like Residential Buildings, Bridges, Industrial Establishment, Drums and all other types of concrete support purposes.
