From Molten Zinc to Rust-Proof Steel: How Galvanizing Works - Video

What exactly is galvanized metal, and why is it used in everything from rooftops and fences to bridges and streetlights? In this video, we explore the science behind galvanization, the history of the process, and why a simple layer of zinc can protect steel from rust for decades. You'll learn how hot-dip galvanizing works, how it differs from electrogalvanizing, and why galvanized steel has become one of the most widely used construction materials in the world.
