For most kinds of building purposes, TMT bars are indispensable and make any structure solid and durable. The majority of people prefer TMT Bars all over the world for construction purposes.
Suppliers tend to deliver quality TMT Bars to maintain goodwill in the market. There are different types of TMT steel available in the market. They are suitable for general construction works and for the construction of heavy-duty structures like bridges, flyovers, dams, high-rise buildings, etc. TMT bars are helpful in equipping a structure with great strength, toughness, and ductility. Many steel companies offer high-quality steel for any structure.
TMT stands for Thermo Mechanical Treatment. TMT bars have a hard outer surface and a soft inner core. Their manufacturing process involves hot-rolled steel wires that are passed through cold water. This makes the outer surface hard and keeps the inner core warm and soft. This contributes to the steel’s corrosion resistance property and increases its durability.
Advantages of TMT Bars over TOR Steel or other Steel
Bending properties: TMT steel bars have excellent bending properties due to the higher ductility achieved by using German technology.
Corrosion resistance: Controlled water cooling prevents the formation of coarse carbides in TMT Bars. This is the main cause of corrosion susceptibility in conventional bars. The absence of surface stresses caused by the cold forming process is another reason for the better corrosion resistance of TMT.
Durability: The carbon content of TMT steel is less than 0.25%. You can use it for welded joints without decreasing the strength of the joints.
Seismic resistance: Steel TMT bars have higher fatigue resistance to dynamic/seismic loads due to their higher flexibility which increases their popularity even among the suppliers. The low carbon content and tough physical properties not only improve elongation but also provide better safety during earthquakes.
Precise gauge control: The gauge control system ensures a precise and accurate weight of the bars by automatically controlling the gauge of the bars within strict tolerances.
Better metallurgical properties: Perfect temperature control system to ensure better metallurgical properties.
Customized product: We design the chemical, metallurgical and physical properties of TMT Bars according to the customers’ requirements. Additional relevant services are provided according to specific customer requirements.
Higher bond strength: The uniform and precise rib pattern of the TMT bar bond optimally with concrete. It gives the best structure greater strength and, therefore, a longer service life.
Perfect rounding: Stress-free rolling by the Loop Scanner system during the rolling process ensures a reduction in the oval shapes typically present in products manufactured in traditional rolling mills. The automated system ensures consistent, uniform, and precise round shapes.
Cost-effective: Consumers can save up to 15% of steel consumption in construction, thanks to the high-strength Fe 550, compared to the current use of Fe 415. TMT bars are sold on a price basis, ensuring better value for money for customers.
Strain aging: Due to the unique scientific manufacturing process and chemical composition, TMT bars are not prone to brittleness during welding or cold forming of welds.
Finer grain structure: Size reduction from billet to bar is made gradually in several stages to achieve a better and uniform grain structure. The refined grain structure gives the bars better metallurgical properties for longer service life.
The TMT bars used these days meet the highest quality standards worldwide. Moreover, TMT steel bars have proven to ne more heat resistance, especially during fires, which adds to the strength and keeps the whole structure safe. That’s why TMT bars are termed as the new generation high strength steel.
