Prepainted Galvanized Steel Coil
When steel components are used to make more complex finished products, they can be galvanized before the product is assembled. This is called pre-galvanizing, or "pre-galvanizing". It may also be referred to as "in-line", "continuous" or "rolled" galvanizing. Essentially, steel components (such as sheets or wires) are galvanized using an automated process before they are cut to size.
This automated process will vary depending on the type of galvanized part. In general, steel components are immersed in a "galvanizing bath" of molten zinc for a short period of time. After the steel is removed from the bath, excess zinc is removed using a mechanical wiper, air knife, or steam. This leaves a relatively thin layer of galvanizing.
