During efforts to revive the steel industry in the late 19th century, there came a point where the traditional steel bars were no longer meeting the needs of the construction industry. There was a need for something better, and something better is what we got. TMT bars are now the top choice for steel reinforcement bars because of their unmatched strength and durability.
(Source)TMT bars get their name from the manufacturing process that gives them high tensile strength and unique features such as flexibility, enhanced bonding, durability, corrosion resistance and more. These features result from special treatments and the addition of specific materials. This blog will explore how TMT bars get these unique features.
High-Tensile Strength
Tensile strength refers to the maximum strength any material can withstand without compromising stability. It measures the ability of TMT bars to resist deformation under tension or stretching forces. Top TMT bar manufacturers produce various grades of TMT bars from Fe 415 to Fe 600. With the tensile strength of TMT bars measuring up to 600 N/mm2, they make an excellent choice for a range of structures, from houses and other residential structures to commercial buildings and dams.
Corrosion Resistance
TMT bars are frequently used for construction in coastal or humid areas, where ordinary steel rebars may succumb to corrosion. TMT bars are made resistant to corrosion with the addition of copper, phosphorus, and chromium in specific proportions.
For the construction of marine and industrial structures or structures in areas with high salinity/acid content in the air, TMT saria manufacturers coat their rebars with Zinc for an added layer of protection.
Weldability
The low carbon content of TMT bars allows hassle-free welding. Moreover, TMT bars don’t require any pre-welding or post-welding treatments, further adding to the convenience. This feature allows construction designers and architects to construct innovative structures without compromising the stability of the construction works.
Fatigue Resistance
The unique manufacturing process of TMT bars makes the outer layer extremely tough while the core forms a soft ferrite-pearlite structure. The outer layer enables the bars to withstand any pressure, dynamic loading, and other stressors that can cause fatigue.
The soft ferrite-pearlite core of the TMT bars allows them to withstand any kind of loading, including seismic loading, significantly reducing the risks of collapse. This makes them particularly suitable for construction in earthquake-prone areas.
Seismic Resistance
The rib pattern of TMT bars provides enhanced bonding with cement and concrete. During an earthquake, it prevents the cement or concrete from slipping, preventing the buildings from collapsing. The soft ferrite-pearlite core allows the bars to absorb a large amount of energy released during an earthquake, ensuring the longevity of structures.
Heat Resistance
TMT bars provide exceptional protection against disasters caused by fires. This is possible thanks to the high thermal stability. TMT bars can resist high temperatures caused by fires and don’t melt easily, keeping structures safe and secure even during a fire. Top TMT bar manufacturers pay special attention to preventing structural damage. This allows the bars to maintain their basic properties, such as tensile strength or crack resistance.
Cost Effective
TMT bars are easier to transport, maintain, and assemble because of their flexibility, lightweight, and higher elongation. This boosts the pace of construction, consequently reducing costs.
The high dimension tolerance of TMT bars provides the same amount of strength and stability with less steel. Due to their superior strength and durability, they last much longer compared to traditional steel reinforcement bars.
Conclusion
This informative blog is aimed to help individuals and companies make informed decisions about TMT bars. TMT bars are undoubtedly an essential component of any construction. Whether a house or a commercial complex, TMT bars protect against dangers such as corrosion, fatigue, heat, seismic loading and much more.
