Rethinking steel rebars
Steel rebars used in construction in the country are dangerously outdated, observed a recent seminar conducted by and for representatives of the steel industry.
Outdated CTD (Cold Twisted Deformed) rebars are still being used by most builders.
There is a need to switch over to high-strength rebars, as 60 per cent of India are in the high-risk seismic zones, 3, 4 and 5.FE 415 is the only type of steel rebars that builders have been using for the past several decades.
The industry needs to be educated in distinguishing between the spurious bar and the real bar. If the per capita consumption of steel in a country is above 250 kg, it is a developed nation; if it is between 50 to 250 kg, it is a developing nation; and anything below 50 kg points to an underdeveloped country. In India, the per capita consumption is only 50 kg.
Today, the steel industry is aspiring to produce 300 million tonnes of steel, of which only 35 per cent is constituted by rebars, which needs to be urgently increased with improved quality.
