Manufacturing Process
In the realm of construction, the choice of materials is paramount, dictating the strength, durability, and safety of structures. Among these materials, TMT (Thermo-Mechanically Treated) bars stand out as a crucial component, widely used in reinforced concrete structures globally. TMT bars are predominantly composed of steel, primarily carbon and other alloying elements like manganese, sulfur, phosphorus and silicon. These elements are meticulously combined to achieve desired mechanical properties, ensuring optimal performance under various stress conditions encountered during construction and throughout the lifespan of structures.
TMT bars can be described as new generation-high strength steel having superior properties such as weld ability, strength, ductility and tensile strength, which meet the highest international quality standards. They are fire resistant and can withstand temperature up to 600c and can retain significant strength even at higher temperatures. Basically, the steel bars are passed through a specially designed water-cooling system, after the bars pass, the outer surface of the bar solidifies while the core remains hot.
This creates a temperature radiant in the bars, after intensive cooling, the bar is exposed to air and the core re-heats the quenched surface layer by conduction, therefore tempering the external martensitic. When the bars are taken out of the cooling system, the heat flows from the core to the outer surface, further tempering the bars which helps them attain higher yield strength. The resulting heat-treated structure imparts superior strength and toughness to the bars. One of the special features of these bars is the ability to withstand bending without losing strength. Their weldability and bonding strength is very high and thus, being cost effective, they are widely used and preferred.
