Generally, galvinizing is done by dipping metal parts in liquid (molten) zinc. Two processes, hot dip and electro galvanized. Hot dip is just that, dip metal in a tin, lead, zink compound which varies depending on the application. Electro galvanized is when metal is connected to a DC source of electricity and dipped into an acid compound while the OTHER electric connection is on a big piece of alloyed tin, lead and zink.
Galvanizing is a process of coating iron with zinc to protect against rusting. The process may be electrochemical, (the origin of the name) nowadays the term is most often appled to a hot dip porcess , simply dunking a clean iron/steel piece into molten zinc pulling it out and letting it cool.
One advantage is economic: Tin is more expensive than zinc. Another, probably more important one, is that zinc, unlike tin, is higher in the electromotive series than iron. Therefore, galvanized iron can continue to provide protection against rust, even when small holes develop in the zinc coating, because the zinc will be oxidized in preference to iron.
It depends on what the metal is going to be used for. A hot dip galvanized steel generally has a thicker zinc layer than an electrogalvanized steel which improves its properties against corrosion. On the other side, the thicker layer might make it inferior in an application in which space is limited.
Zinc is used in galvanizing to protect iron or steel from corrosion. The process involves coating the metal with a layer of zinc to provide a protective barrier against rust and other environmental factors.
The process of depositing zinc on iron is called galvanization. This technique is primarily used to protect iron and steel from corrosion, as zinc acts as a sacrificial anode, preventing rust formation. Galvanization can be achieved through several methods, including hot-dip galvanizing and electro-galvanizing. The resulting zinc coating provides a durable barrier against environmental elements.
Galvanizing protects steel from oxidization (rusting).
Galvanizing is the process of dipping steel or iron into a bath of molten zinc. The zinc coating served as a corrosion prohibitor, and was applied to structural parts, sheeting, pipe, various containers, and hardware.
jigging is the name of the process of hanging items on a wire prior to suspending into molten zinc to galvanize the steel
"Galvanized" is an adjective used to describe steel which has been coated with zinc metal. Galvanized steel is quite well protected from corrosion by the zinc coating which provides the steel with both physical and chemical protection. There are currently 3 processes which are used for galvanizing steel: (1) hot dip galvanizing, (2) electrogalvanizing, and (3) thermal diffusion galvanizing.
Zinc
Electro galvanizing is the process of applying a protective metallic coating to an underlying piece of metal.
Typically, galvanizing refers to hot-dip galvanizingwhich is process of submerging steel parts into molten zinc. Zinc will melt at 787.15 °F. In a galvanizing environment, most of the smoke is flux burn-off from the preparation process. Depending on the specific galvanizing company, zinc is generally maintained between 820 - 860 °F.Hot-dip Galvanizing Zinc Temperature Range820 - 860 °F (449 - 460 °C)Zinc Melting Point787.15 °F (419.53 °C)
duration depends on thickness, size and configuration of what is being galvanized The steel is dipped into the zinc tank for 2-10 minutes

Coatings Cathodic Protection If steel- galvanizing
Steel is a base, hence the reason it corrodes. The Iron and other elements in the steel are formed to create 'steel', and hardened in a process called galvanizing to stop the corrosion. Also by definition, any metal is a base.
Galvanizing is a process of coating sheet steel with zinc. It makes the steel rust resistant, thereby prolonging it's life. That's why the galvanized roof lasts longer.
