Why aren’t the bottom of the cast iron grates enameled?
Due to the enameling procedure, only the tops can be enameled. The top & bottom can be furnished with an acid resistant coating or the bottom of the enameled grates can be painted. However, this requirement should be specified and ordered as such. The enameling procedure is an industry standard that has been supplied this way for many years. Only the top of the grate is where the liquid stands.
