The demand of zinc is expected to double in India in the next five to 10 years on the back of huge investments in infrastructure sector, including steel, International Zinc Association said on Sunday. The demand for zinc in India depends largely on the growth of the steel market as zinc is mainly used to galvanise steel to protect it from corrosion.

The market for primary and refined zinc in India is currently close to 800 to 1,000 tonnes (per annum) and has a great opportunity to increase with all the developments that we are witnessing in India. We see huge investments in additional steel capacity and ...steel still needs to be protected by galvanized coatings. We see a lot of plans and investments going on for new galvanizing lines. So I expect a strong role for zinc in India," International Zinc Association Global Director Martin Van Leeuwen told PTI in an interaction. The current demand for zinc in India
