Every bridge, transmission tower and highway railing in India has a quiet enemy: rust. Now, the company that produces more integrated zinc than anyone else on Earth has given galvanisers two new weapons against it. Hindustan Zinc has launched VedAZ and VedAyush, two next-generation zinc alloys unveiled on 3 November 2026 at ZnAL Confluence 2026, designed to make galvanised steel more consistent, more durable and longer-lasting — from coastal ports to humid factory floors.

Galvanising — coating steel with a thin layer of zinc — is how India protects the steel inside its infrastructure, vehicles and power systems from corrosion. The company points to a 2026 CII–Nomura Research Institute report estimating corrosion-related losses at approximately 4.3% of India’s GDP each year, which is why coating quality matters far beyond the factory gate. When a coating is uneven or weak, the steel beneath it starts losing the battle years earlier than it should.
VedAZ: precision for the galvanising bath
VedAZ is a specialised zinc-aluminium master alloy, built for the galvanising bath itself. The company says it gives galvanisers finer control over aluminium levels in the bath, keeping the chemistry stable so coatings come out uniform in thickness, with a better surface finish. Its optimised composition is also designed to reduce dross formation and zinc losses, helping manufacturers use their material more efficiently and deliver higher-quality galvanised products, run after run.
VedAyush: armour for the harshest environments
VedAyush is a specialised zinc-aluminium-magnesium alloy, engineered for the places where ordinary coatings struggle most. The company says the addition of magnesium improves corrosion resistance, coating adhesion and surface stability, particularly in high-humidity, coastal and demanding industrial environments. Its applications span infrastructure, automotive components, consumer appliances, power transmission and industrial systems — the very places where a coating failure is most expensive to fix.

Made in Rajasthan, for India and the world
The new alloys are manufactured through the company’s wholly owned subsidiary, Hindustan Zinc Alloys Private Limited, which operates a 30,000-tonne-per-annum zinc alloy melting and casting facility at Rajpura Dariba in Rajasthan. Backed by Hindustan Zinc’s integrated operations, the facility strengthens domestic availability of application-specific zinc alloys and supports a more resilient manufacturing supply chain. The alloys join an existing specialised portfolio that includes the zinc die-casting grades HZDA-3 and HZDA-5, with HZDA-5 also holding Bureau of Indian Standards (BIS) certification.
“We see significant scope to grow our value-added zinc business across infrastructure, automotive, engineering and consumer products,” said Amarendu Prakash, CEO and Whole-time Director of Hindustan Zinc. “Customers in these sectors need specialised grades tailored to their manufacturing processes and performance requirements. VedAZ and VedAyush broaden the range of needs we can address and create opportunities to build closer customer relationships.”
Hindustan Zinc, a Vedanta Group company headquartered in Udaipur, is the world’s largest integrated zinc producer and among the top 10 silver producers globally, supplying more than 40 countries. With VedAZ and VedAyush, it is pushing further up the value chain — turning the zinc India already produces into smarter, more specialised materials that help the country’s steel last longer, look better and stand up to whatever the climate throws at it.
