tata tiscon SD

Introduction

Buildings and infrastructure in seismic zones have to be better prepared for earthquakes and so have special criteria for reinforcement. TATA Tiscon SD (Super Ductile) high strength ribbed TMT reinforcement bars are particularly suited to meet these requirements. Its superior ductility ensures that it has more pliability and hence, can be bent to a much larger extent. That is, it has a higher threshold of ultimate tensile strength. This is ideal for safety of constructions in frequent earthquake zones.

Specification

Tiscon follows a novel process in the production of TATA Tiscon SD rebars that involves use of special chemicals and treatment post rolling. This makes the rebars more ductile, with great capacity to absorb energy beyond the yield limits. This is an essential quality in preventing collapse buildings during earthquakes.

TATA Tiscon SD is available in sizes from 6mm to 32mm. A comparison chart on specifications Tiscon SD and BIS standards is mentioned below –
