Cold galvanization (electro-galvanizing) is in electroplating groove through the current mono-direction make zinc plated metal appearance, gradually in production speed is slow, coating thickness, thinner, usually only 3-15 microns, the appearance of brightness, corrosion resistance, general months will rust.
Relative electro-galvanizing, galvanized lower cost of production and environmental impact than electroplating.
