Fire Resistance
Good quality TMT bars have higher thermal stability and retain more than 80% of their ambient temperature yield strength at 300° Thus makes the concrete structure safer in fire hazards.
Cost Effectiveness
Batch to batch consistency and uniform sectional weight per unit minimizes steel wastage and makes it beneficial for the customers to buy TMT bars in small quantities as well.
Weldability
Low carbon content in TMT bars makes it easy for welding works. Excellent weldability in steel rebar requires no pre or post welding treatment and makes it easier for the construction workers..
Bendability
Advanced quenching process toughens the surface layer yet the core remains soft, this in turn makes the TMT bar easily bendable. The cutting and bending strength can be determined as per the Bar Bending Schedule (BBS) certification.
Dimension Tolerance
Nominal values specified in BIS code determine the grades of dimension tolerance. Closer values of sectional weight ensure higher meterage per unit weight in good quality TMT bars, compared to ordinary rebar..
Chemical Composition
Certified composition of Sulphur, carbon and phosphorus and exclusion of unwanted materials such as cast iron, non-metallic and non-ferrous etc. are the determinants of a good quality TMT bar.
Seismic Resistance
Seismic resistant structure is dependent on its reinforcement strength. Buildings that are compliant to the recent seismic building code and standards are obviously more capable of withstanding the earthquake damages. TMT bars along with a good concrete bond, fortify the tensile strength of a structure. However, grades of TMT bar differ at different seismic zones.
