Kavalakkat TMT Fe 500 XD
Kavalakkat manufactures high-quality TMT steel bars by implementing modern technology. TMT bars have superior properties such as superior strength, higher ductility, better weldability and bendability.
Thermo mechanically treated (TMT) steel, can be described as new-generation-high-strength steel having superior properties which meet the highest international quality standards.
The role of ductility in steel bars, the geography of India is divided into 4 seismic zones II, III, IV and V in the earthquake zoning map, of which zone V is the highest and zone II is the lowest level of seismic activity. Only buildings with high ductility are able to withstand seismic activity and maintain their structure. It is the TMT steel bars used in construction that give buildings this feature compared to normal grade TMT steel bars, Kavalakat TMT-XD (Extra Dutile steel bars) are able to withstand seismic forces earthquakes, ensuring better strength and security.

Here are some key properties of TMT Steel Bars that you need to remember:
Yield Strength
A Yield Strength or yield milt of material is defined in engineering and material science as the stress at which a material begins to deform plastically, prior to the yield, the material will deform elastically and will return to its original shape when the applied stress is removed.
Tensile Strength
Tensile Strength is a measurement of the force required to pull something such as rope, wire or a structural beam or a TMT steel bar (in this matter) to the point where it breaks. The Tensile strength of a material is the maximum amount of tensile stress that it can take before failure, for example, breaking.
Elongation
Elongation in continuum Mechanics is the confirmation of a body from a reference configuration to a current configuration through an external unbalanced force.
