Electrogalvanizing is an electroplating technique used to place a layer of zinc metal on top of a steel surface. It involves immersing a steel component into a solution containing zinc salts, followed by the application of electricity to induce an electrochemical reaction on top of the steel. Compared to hot dip galvanization, electrogalvanizing provides a thinner coating and more aesthetic appearances.

Bare steel surfaces are prone to corrosion because they contain iron that oxidizes when exposed to oxygen. Zinc, being more anodic than iron, becomes a sacrificial anode and prevents corrosion of the underlying steel.

Steel sheets and wires are often electrogalvanized. Common applications of the technique occur in the automotive and appliance industries.
