Gagan Ferrotech Ltd. manufactures Thermo Mechanically Treated re-inforcement bars using the world renowned Thermex Technology. “Gagan TMT” Re-Bars are produced in the state-of-art plant under close supervision of its front-line senior engineers. Gagan TMT is the only one that is produced through a thorough process with adequate capabilities, process optimisation and strict control that should be used.

Cost Saving

Gagan Thermex TMT Bars are very cost effective and saves steel up to 20% being technically superior and having higher tensile strength that other TMT bars.


Fe415: Houses, small buildings etc

Fe500: Houses, high rise buildings, industrial constructions,bridges, roads, dams etc.

Fe600: Houses, high rise buildings, industrial constructions,bridges,roads, dams etc.

Better fatigue strength, 100% weldability, excellent bendability, strong and extra casting grip with cement

 Better control on chemical composition with automatic rolling scientific design for better quality

 Tensile strength 20% extra compared to ISI
