Galvinized steel is simply steel with a thin layer of zinc on the surface - it is placed there electrochemically (through galvanic action), hence the name.

Galvanise is not a metal.
Steel is galvanised by covering it in a thin layer of zinc. This stops oxygen and water reaching the steel's surface and causing rust

I used to work in a steelworks that did this.
We had a 20 ton bath of molten zinc and the 3km long coils of 1m wide steel ( 1mm thick ) were run through the zinc bath. As it came out of the bath the molten metal was blown with hot air to remove most of the material leaving a smooth thin layer of zinc.
The steel went straight up after the blowers and was solid in about 40 metres.
The steel ran at 120 metres/minute so it was scary when it got stuck and 100's metres of steel sheeting flew everywhere.
The plant (line) was over half a mile long.
Its used in all sorts of products such as washing machine sides, buildings etc.

Galvanise is a process where steel is coated with zinc. Usually the steel is hot dipped in molten zinc

to galvanise means to electroplate.
it comes from galvani, a scientist who discovered that dead frogs legs could be made to twitch if an electric current were applied to them (i'm sure he discovered lots of useful stuff, but thats just what i recall from science class :-)
you usually galvanise steel/ iron with zinc to prevent rust

Che is spot on give him the ten points

the hot dip galvanized steel is pretty good for corrosion protection
