Description
TATA Tiscon 500 D is a high strength ribbed TMT reinforcement bar. The consistency in strength across the rebar is maintained by reducing the impurities like Sulphur and Phosphorous to a level below 0.075%. ‘500’ refers to the strength of the rebar in MPa and ‘D’ refers to ductility of the rebar. TATA Tiscon 500 D conforms to the latest standards (last revision 2012) set by Bureau of Indian Standards (BIS).
SpecificationTATA Tiscon 500 D is manufactured through a superior quality and controlled steel making process to diminish the levels of impurities like Sulphur and Phosphorous. These impurities decrease the strength of steel in extreme hot and cold conditions. Therefore lower these values the better.
TATA Tiscon 500 D is available in sizes from 6mm to 40mm. A comparison chart on specifications of 500, 500 D and BIS standards is mentioned below –
