Icon 550 DS
WELCOME TO A NEW TMT ERA WITH DS SURAKSHA
After 30 years of constant research and experience, Icon Steel has launched a new age TMT bar – DS Suraksha. Usually, a higher grade of steel promises to have a higher yield of strength but a decrease in ductility. With this quantum leap in the steel industry with DS Suraksha, the composition of the TMT bar has the perfect balance of Ductility (D) and Strength (S).
The DS TMT bar matches the higher requirement of safety in present-day structures as the scale of the construction and its utilization/occupancy are much higher than in previous decades. It is also versatile for use in all geographies and district zones. This is a material that successfully addresses the concerns of an engineer regarding major projects – whether infrastructure or residential. DS TMT bar is a versatile and safe option as it offers tensile strength, lower maintenance, and is damage resistant.
