You can galvanize any steel item, provided that it is perfectly polished and set and designed for a correct draining of the liquefied zinc. This means that there must be no rust on it, no grease, no sludge or drooling: pre galvanization treatments (pickling, fluxing, sandblasting) ensure this, but a correct design is required in order to let zinc glow on surfaces without any block. Draining holes and feasible shapes are compulsory in order to avoid bad galvanization and manufacturing risks.
