For temporary identification, water-soluble paints or markings are recommended. Oil-based paints should not be used as they must be removed manually before galvanizing. For temporary identification, use heavily embossed metal tags wired to the work.

For permanent identification, intended to remain legible after galvanizing, the fabricator should provide heavily punched or embossed figures either on the work or on steel (not aluminium) tags wired to the work.
