Hindustan Zinc Limited has announced that its premium-grade zinc was used in galvanising India’s heaviest transmission steel pole structure. The massive 400 kV dual-pole structure, standing at ~57 metres, was galvanised using a mix of Hindustan Zinc’s low-dross jumbo special high-grade zinc and SHG zinc ingots. 

 

The company stated that this process provides protection against corrosion, enhancing the structure’s durability by creating a barrier against air, water, heat, and pollution. Designed and manufactured by Skipper Limited, this structure is part of the 400 kV Quad Moose DC Transmission Lines Project under Andhra Pradesh’s Pinnapuram Integrated Renewable Energy with Storage Project. 

 

Skipper Limited, India’s largest manufacturer of power transmission and distribution structures, operates one of the biggest galvanising facilities in the country. The dual-pole structure, weighing over 200 metric tons, is optimised for use in urban areas, offering a space-efficient alternative to traditional four-legged lattice towers. The zinc layer applied during the galvanization process extends the structure’s lifespan by 30-35 years. This structure, specifically designed for coastal areas prone to corrosion, is particularly important in regions like Andhra Pradesh, where high humidity, salt, and moisture levels accelerate rusting and compromise structural integrity.

 

Zinc, known for its sacrificial properties that protect steel, plays a crucial role in bolstering India’s infrastructure, including railways, roadways, bridges, and power transmission systems. The galvanisation process significantly reduces corrosion, lowering maintenance and replacement costs. A report from the International Zinc Association highlighted that corrosion costs India up to 5% of its GDP, higher than other nations due to lower utilisation of galvanised coatings. 

 

Arun Misra, CEO of Hindustan Zinc, emphasised the company’s commitment to providing innovative products for building durable infrastructure, collaborating with industry leaders like Skipper Limited to strengthen India’s critical infrastructure projects. 

 

Sajan Kumar Bansal, Managing Director of Skipper Limited, echoed this sentiment, underscoring the success of their collaboration in advancing the Atma Nirbhar Bharat initiative.

 

Hindustan Zinc continues to innovate, offering one of the world’s largest zinc product portfolios and recently launching EcoZen, Asia’s first low-carbon “green” zinc, manufactured with renewable energy. EcoZen reduces the carbon footprint by 75% compared to the global average, contributing to decarbonization efforts and offering customers a sustainable edge.
