The country’s cathodic protection (CP) market—an essential technology used to prevent corrosion in pipelines, marine structures, and buried infrastructure—is projected to grow from USD 186.9 million in 2025 to USD 304.4 million by 2035, registering a compound annual growth rate of 5.0%, according to a recent analysis by Future Market Insights.
That isn’t just market growth. It’s a signal of long-term strategic thinking. South Korea is preparing for a future in which infrastructure resilience is non-negotiable. And, let’s be honest, the U.S. and much of the West are falling behind.

Beneath the Surface: The Corrosion Crisis
Corrosion is not glamorous, but it’s dangerously underestimated. Pipes, bridges, and foundations deteriorate silently—until they fail catastrophically. South Korea sees that threat clearly. The country is ramping up investment in CP systems as a first line of defense, not a last-minute patch. That mindset is what’s driving their market forward.
By contrast, the U.S. still treats corrosion prevention as a footnote. And while we rebuild aging infrastructure piece by piece, South Korea is building systems to last decades longer, with corrosion protection baked into the design from day one.
Why South Korea’s CP Push Matters
South Korea isn’t just investing in CP because it’s smart—it’s necessary. The nation is expanding its offshore infrastructure, scaling renewable energy systems, and modernizing transportation links. All of those projects rely on corrosion-resistant engineering. Without robust cathodic protection, they won’t endure.
And this isn’t just a matter of throwing equipment at the problem. The country is deploying smarter, more efficient systems—adaptive designs that respond to environmental conditions, consume less energy, and reduce the need for costly repairs down the road.
This kind of forward-thinking infrastructure policy deserves more attention in Western planning circles. South Korea is showing what a national corrosion strategy actually looks like—and how it ties directly into economic and energy resilience.
The West’s Lagging Response
What’s happening in South Korea puts a spotlight on what’s not happening elsewhere. In the U.S., corrosion is still seen as a maintenance issue, not a strategic one. Budgets for corrosion control are often the first to be cut, and CP systems are frequently retrofitted instead of integrated from the beginning.
That reactive approach is costing us—not just in dollars, but in reliability, downtime, and public safety. Failures in buried pipelines, foundations, and critical infrastructure could often be prevented with a proactive CP strategy. But we continue to accept a break-fix model, while South Korea is moving toward build-prevent-protect.
Looking Ahead: A Global Imperative
South Korea’s investment in cathodic protection is more than a domestic win. It’s a blueprint for how industrialized nations should be addressing the silent crisis of corrosion. Infrastructure resilience isn’t just about steel and concrete. It’s about designing systems that resist failure over decades—not just survive to the next repair cycle.
If the global community wants to build smarter, greener, and longer-lasting infrastructure, cathodic protection must move from the margins to the mainstream. It’s not optional. It’s foundational.
And right now, South Korea is leading the way—while others risk learning the hard way.
