IZA Calls for Use of Galvanized Rebars for Costal Infrastructure
Leading industry association International Zinc Association along with India’s largest and world’s second largest zinc-lead miner Hindustan Zinc Limited organized a knowledge webinar to throw light on emerging, sustainable construction technologies like Continuous Galvanized Rebar. IZA Belgium Director, Technology & Market Development Mr Martin van Leeuwen said “India is one of the fastest growing economies in the world. The recent budget allocation in infrastructure development along with ambitious projects by central and state governments only emphasize how crucial this sector is for the development of the nation. At the same time, the annual losses and infrastructure failures due to corrosion, especially on the coastal regions poses a roadblock in these plans. This calls for an urgent need to deploy effective and sustainable technologies that can stimulate growth in the sector. CGR technology has proven to be extremely effective in resisting corrosion and giving strength to the structure. As the government of India looks to strengthen Indian infrastructure, it calls for the need to adopt durable and proven corrosion protection methods, like galvanization of steel reinforcement for concrete structures.”
IZA Director (India) Dr Rahul Sharma added “India loses as much as 5-7% of its Gross Domestic Product every year on the account of corrosion. These are staggering figures that require immediate and appropriate measures by authorities to control further damage.”
International Zinc Association in collaboration with Madhav KRG Group had inaugurated South Asia’s first ever Continuous Galvanized Rebar Manufacturing Facility last year in Punjab. Continuous Galvanized Rebar are value added rebars for higher life and low maintenance of infrastructure to provide significant cost savings compared to other corrosion resistant rebar systems. It offers on-site formability of the finished product, superior corrosion resistance in concrete at a price cheaper than other corrosion resistant rebar like Epoxy Coating & CRS rebar. This technology provides significant cost savings compared to other corrosion resistant rebar systems together with the advantage of preventing corrosion, thereby enhancing the lifetime of the underlying steel.
India has a coastal line that extends over 8000 kms. Coastal areas including parts of Maharashtra, Gujarat, Andhra Pradesh, Tamil Nadu, Kerala, West Bengal, which are prone to corrosion because of salty atmosphere leading to frequent maintenance requirements thereby adding to loss of material and impact on the productivity. Next to direct costs of repairing or rebuilding damaged infrastructures, indirect costs resulting from road closures, road diversions, building closures and personal accidents due to failing structures shall be taken into account.
