# Galvanized Steel

Galvanized steel is a critical material in civil and industrial engineering, fundamentally defined by its protective [zinc](https://www.o2oh.com/glossary/zinc) coating.

This coating, typically applied through [hot-dip ](https://www.o2oh.com/glossary/hot-dip-galvanizing)[galvanizing](https://www.o2oh.com/glossary/hot-dip-galvanizing), prevents corrosion via a dual mechanism: a physical barrier against the environment and, crucially, sacrificial corrosion.

Since zinc is electrochemically more active than iron, it corrodes preferentially, thereby protecting the underlying steel even if the coating is scratched.

This process dramatically extends the material's lifespan, minimizes maintenance cycles, and ultimately contributes to the sustainability of infrastructure projects.
