Pre-galvanized steel refers to steel which was galvanized while in sheet format, thus prior to further manufacturing. Pre-galvanization is also known as mill galvanized, due to the fact that the steel sheet is rolled through molten zinc. After the sheet is sent through the mill to be galvanized it is cut to size and recoiled. A specific thickness is applied to the entire sheet, for example pre-galvanized Z275 steel has a 275g per square meter zinc coating. One of the advantages which pre-galvanized steel has over hot dip galvanized steel is that it has a better appearance.

pre-galvanized materials are used for a wide variety of products including conduit, lip and open channels.
