TMT (Thermo-Mechanically Treated) bars are high-strength bars made using a unique process of heat treatment and cold working, which gives them superior strength, ductility, and resistance to corrosion compared to mild steel.
TMT bars are designed with a tough outer surface and a soft inner core, giving them excellent bendability and the ability to withstand seismic forces, making them ideal for earthquake-resistant constructions.
Look for TMT bars that are ISI certified, manufactured by reputed companies, and have a good balance of strength, ductility, and corrosion resistance. Checking the brand reputation and customer reviews can also help in choosing high-quality TMT bars.
These grades refer to the yield stress of the bars. Fe 415 has 415 N/mm² yield stress minimum, Fe 500 has 500 N/mm² minimum, and Fe 550 has 550 N/mm² minimum. Higher grades offer better strength but may be less bendable.
Yes, TMT bars are highly corrosion-resistant due to their strong surface and high-quality steel, which helps them resist rust and corrosion, especially in areas with high humidity or exposure to moisture.
The price of TMT bars is determined by factors such as raw material costs, production processes, brand reputation, grade of steel, and local market conditions. Prices can vary from region to region.
Branded TMT bars offer better quality control, higher strength, more reliability, and long-term durability. They are produced by BIS & ISO-certified companies and adhere to strict quality standards.
TMT bars are designed to last for several decades if used correctly. Their corrosion resistance, strength, and ductility ensure that they provide lasting durability for structures.
Yes, TMT bars are versatile and can be used in both residential and commercial construction due to their strength, flexibility, and ability to withstand heavy loads and environmental conditions.
HYSD (High Yield Strength Deformed) bars are produced through a process where the bars are subjected to mechanical deformation under high force, which induces residual stresses within the steel, making them more prone to plastic deformation and corrosion. In contrast, TMT bars undergo a thermomechanical treatment process that imparts a tough outer surface while maintaining a ductile inner core, offering superior corrosion resistance, bendability, and earthquake resistance compared to HYSD bars.
