Kairali TMT Steel Bars are available in sizes ranging from 8mm to 32mm so that you get to choose the best product for your need.
Owing to our international production standards, Kairali TMT Steel Bars have an unique blend of strength and ductility. The tensile to yield strength ratios are greater than 1.12. In normal bars, where the increase in the yield strength of the bars is accompanied by loss of percent elongation, Kairali TMT is superior as the loss is negligible and elongation values are higher that specified.
Tough outer layer and the ductile core of the Steel Bars result in Excellent Bendability.
Presence of Martensitic Layer on the outer surface and formation of adherent scale file due to water quenching during rolling ensure better corrosion resistance properties of Kairali TMT Steel Bars.
Quality of the raw materials used and the perfect chemical combination helps Kairali TMT Steel Bars withstand the torments of nature.
