Definition - What does Line Plating mean?
Line plating is a technique to electroplate a thin layer of a protective corrosion-resistant metal onto a metallic surface in an efficient manner through the use of repetitive automated machinery.
Metallic structures that are line plated are typically used collectively in a processing plant or some other industrial application that requires corrosion resistance.
Corrosionpedia explains Line Plating
Line plating can be performed with several protective metals such as chromium, zinc, copper or cadmium depending on the base material type to be electroplated.
