Sangam TMT Q&A: Top 10 FAQs

1. What is Sangam TMX TMT?
Sangam TMX bars are thermo-mechanically treated rebars processed using the Thermex Tempcore method, which creates a hard martensitic outer layer and a ductile inner core. This dual microstructure, combined with precision-controlled rib patterns, delivers superior yield strength, excellent ductility, strong concrete bonding, and easy weldability—ideal for earthquake-resistant structures and heavy-duty applications.


2. What is the history of Sangam Steel?
Sangam Steel, based in Wardha, Maharashtra, expanded under the OfBusiness Group from a regional re-rolling facility to a fully integrated manufacturer. The company installed two induction furnaces, automated billet casting, and advanced rolling mills capable of producing up to 500,000 tonnes annually. Since its early days, Sangam has focused on quality, sustainability, and cost-efficiency to become a leading TMT brand in central India.


3. Who owns and runs Sangam Steel?
Sangam Steel operates under the OfBusiness umbrella and is led by a team of industry professionals and manufacturing specialists.
