Abstract
A public specification of baked enamel coating for metallic building materials does not exist in present Japan. Therefore, when the baked enamel coating is adopted, a detail coating specification has been specified in the design document. However, it is usual that the coating specification depends on the manufacturer and a designer and an inspector for the project watch only the appearance of the product. In this paper, it is introduced that a detail of a design specification and the manufacturing method were considered by the test coating results for a real project. And it is proposed that an actual decision method for a baked enamel coating specification and its standardization based on the above results.
