The severe earthquake that struck Nepal on April 25, 2015, claimed almost 9,000 lives, many thousands more were injured, and 600,000 structures in Kathmandu and other nearby towns were either damaged or destroyed. The staggering figure of structural damages forces us to believe that it is not the earthquake that kills but poorly built buildings.
Nowadays TMT steels are commonly used in constructions. What is TMT? Why is it used than other types of steel? Well, before TMT was introduced Mild Steel (MS) bars, Cold Twisted Deformed (CTD) bars were primarily used with concrete for constructing buildings. Those steel were graded Fe 250 but their low strength was a problem for buildings requiring more strength.
Continuing from the previous blog, we will be taking a close look at how TMT bars changed Indian construction sector. One of the huge factors which not many discuss is that India is itself a source of cheap and high-quality TMT bars. The steel industry has always one of the successful heavy engineering sectors in India. This meant that India always had a steady supply of TMT bars no matter the situation in the markets.
