Manufacturing method of a coated metal product

摘要

A coated metal product (10) is disclosed in which the surface of a ferrous component (11) is coated using an anticorrosive layer (12), and the surface of the anticorrosive layer is coated using a coating film (13). The coating film has numerous very small uncoated portions (14) for exposing the surface of the anticorrosive layer to the exterior of the coated metal product, rather than the entire surface of the anticorrosive layer being coated.
