Q:I would like to build steel galvanization plant.: That's depending on what type of metal you want to cover the steel parts in the galvanization process. The galvanization in words refers only to that kind of process which is using electric deposition of a metal through a bath of a electrolyte from a plate containing pure metal needing to be deposed on steel tide at the anode electrode or + polarity and at the other side (other electrode, cathode or - polarity). There needs to be a certain recipe of mixed salts for creating very tight and uniform growth crystals, for not being corroded or leafed away with time. There are certain salts which provide this king of growing in the same time with the polished look of the piece galvanized. This salts can be dissolved in water, for creating the electrolyte or being melt (which is not so safe technique) and used and kept like that. The dipping is no so used any more and it can not be called galvanization. More recent techniques use hot plasma blowers, meaning a torch with plasma and a wire of the specific metal to be deposited being melt in the plasma and blown to the surface of the steel part. Anything you'll do you have to deal with the local Environmental Agencies and with the tap water supply/ sewerage administrator, because you;ll have to make a contract with them for you to show that you retain the hard metals from the water dropped to sewerage, if any.
