Did you think the world’s largest hydropower project was still China’s Three Gorges Dam?

In fact, a new giant is rising — the Yarlung Tsangpo Hydropower Project, expected to be three times the scale of Three Gorges, has officially broken ground.

Based on previous experience, this project is estimated to require 4 to 6 million tons of specialty steel.

Each ton of steel needs 20 square meters of protective coating, at a cost of around 30 RMB per square meter.

That means just the anti-corrosion work alone could cost 2.4 to 3.6 billion RMB — or $330 to $500 million USD.

A staggering, often invisible investment — but one that protects the entire foundation of the project. Once completed, the dam is expected to generate 300 billion kilowatt-hours of electricity annually — enough to power 300 million people for a year.

But behind this engineering miracle lies an overlooked defense line: heavy-duty anti-corrosion coatings.

👉 Without corrosion protection, there is no long-term safety.

👉 This isn’t just paint.

👉 It’s the shield of a century-level project.

Projects of this scale demand extreme performance:

Aging resistance. Corrosion resistance. Moisture resistance. Long-term durability — there’s no room for compromise.

At Mengneng, we specialize in graphene-based heavy-duty coatings.

Whether it’s bridges, hydropower stations, or marine structures,

we’re ready to provide long-lasting solutions for the most extreme environments.
