IN CONCLUSION

It is estimated that that steel consumption in India will rapidly rise in the next 10-15 years to reach a level of 140-150 million tonnes per year by 2020 of which 55% (77mT) will be long products. Rebar demand will see more than a five-fold jump to around 35-40 mT/year to allow for development of the vast hinterland. The best of quenching and tempering technologies are today available in the country and Q & T rebars have already made a dent in the market. By 2020 over 90% of the rebars used will be Q&T rebars. It is imperative that the B. I. S. put into place a relevant Code for rebars at the earliest so that the country utilises this technology to its full potential – savings in steel consumption and safety. The new Code could be on lines of the one adopted by New Zealand. It should make it mandatory for all rebars to have marks that make it easy for the Grade and name of producer to be identified. This will clean up the rebar sector and be beneficial to the entire construction industry.
