FAQ's
TMT (Thermo-Mechanically Treated) bars are high-strength reinforcement bars with a tough outer core and a soft inner core, used in construction to provide enhanced strength and durability to concrete structures.
The 'Thermex' process is a patented technology involving rapid quenching of hot-rolled steel bars, resulting in a hardened surface layer while maintaining a ductile core, thereby enhancing the strength and flexibility of the TMT bars.
TMT bars are available in diameters ranging from 8 mm to 32 mm, catering to various construction needs.
Common grades include Fe 415, Fe 500, Fe 550, Fe 500 D, and Fe 500 CRS, each indicating the yield strength of the bar in megapascals (MPa).
Higher elongation indicates better ductility, allowing the bars to withstand deformation under stress without breaking, which is crucial for earthquake-resistant constructions.
Yes, quality TMT bars have better corrosion resistance, ensuring no rusting even after prolonged exposure, which enhances the longevity of structures.
Yes, TMT bars maintain their strength even at high temperatures up to 600°C, making them suitable for structures exposed to fire hazards.
SRJ Thermex TMT bars offer higher elongation, better corrosion resistance, thermal stability, excellent straightness, higher weldability, earthquake resistance, prominent ribs, and higher ductility, ensuring superior performance in construction.
While concrete is strong in compression, it is weak in tension. Reinforcing it with steel, which has high tensile strength and ductility, provides the necessary support to handle various stresses, ensuring structural integrity.
TMT bars provide the required ductility and flexibility to absorb and dissipate energy during seismic activities, reducing the risk of structural failure.
Key factors include raw material quality, manufacturing process, consistent quality throughout the bar, bonding with cement, low impurities, ductility, ease of application, and transparent pricing.
Prominent ribs, achieved through CNC rib cutting, enhance the bonding between the TMT bar and concrete, improving the overall strength of the structure.
Yes, TMT bars have excellent weldability due to their optimal chemical composition, allowing for secure joints without compromising strength.
Quality assurance ensures that TMT bars meet stringent standards through continuous monitoring and testing, covering aspects like customer satisfaction, manufacturing excellence, and organizational performance.
SRJ Steel employs advanced equipment and adheres to a comprehensive quality control process, including inspection, control, assurance, and Total Quality Management (TQM), to deliver superior steel products.
