Jagshakti GOLD Fe 500D
Technically, in a construction, while concrete takes care of compressive stress, steel takes care of the tensile stress. JAG SHAKTI GOLD Fe 500D is a high strength ribbed TMT reinforcement bar. The consistency in strength across the rebar is maintained by reducing the elements like Sulphur and Phosphorous combined to a level below 0.060%. '500' refers to the strength of the rebar n MPa and 'D' refers to ductility of the rebar. JAGSHAKTI GOLD Fe 500D conforms to the latest standards set by Nepal Standards (NS). JAGSHAKTI GOLD Fe 500D is not just a brand; it is a symbol of TRUST.
Lets talk about difference between Fe 500 and JAGSHAKTI GOLD Fe 500D TMT bars.
Fe- 500 Grade : Fe 500 grade TMT bars were introduced as an one step up technological marvel over conventional Fe 415 grade product. The superior tensile strength of Fe 500 TMT bars resulted in approximately 17% lesser consumption of steel in construction.
TFe-500D: This category of TMT bars demonstrates higher tensile strength and ductility over and above normal grade TMT bars. D variety TMT bars are manufactured through special category of billets and critically controlled thermal treatment during manufacturing process. The best part of D type TMT bars are the ideal products for earthquake resistance and totally free of mechanical fatigue.
Fe 500D is one of the best TMT steel bars available today. The letter "D" in Fe 500D implies ductility which means that the steel bars have a higher percentage of elongation. They also have lower quantities of carbon, sulphur and phosphorous, which helps in preserving the steel and resisting earthquake shocks in future. There is supreme connection between the steel and concrete. Concrete has only high compressive power, and hence when it is combined with the TMT steels bars, together they become ductile and highly tensile. TMT bars can be used in a variety of projects like bridges, dams, flyovers, buildings, railways and any other construction work.
