Will galvanized steel rust if you grind it?

Answer 1

Yes , eventually it does rust but it takes a long time, in normal weather conditions, if you subject it to extreme conditions, it does not last as long, but still lasts quite a bit longer than normal steel.

So eventually you get rust; how can you deal with that and not get it spreading?

Answer 2

Because iron reacts with oxygen to form Fe2O3. Galvanized metal is a metal that is coated with a layer of zinc. As zinc oxidizes and reacts with gases in the atmosphere it will eventually form a protective coating of zinc carbonate that will protect both the zinc and the iron beneath it. T

Answer 3

Galvanizing steel with a more reactive metal like zinc helps because it reacts with air or water by losing it's electrons instead of steel and so prevents steel from rusting.....hope that helped XD

Answer 4

A galvanized nail has a rust-proof coating of tin, however, that coating can get scratched, in which case the iron is slightly exposed and can begin to rust. Eventually even galvanized nails rust, but they do last longer than the non-galvanized variety.

I've read a lot of misinformation on the web, but this is the first time anyone has claimed that tin is used for galvanizing nails. It is zinc that coats a galvanized nail. The rest is correct.

Answer 5

This depends on the thickness of the steel and the galv - galvanisation is the process of adding a zinc layer to the outside of the steel to protect it from the elements. On average it would be expected to last 30years +, although some sources say upto 70years before the zinc is worn away

Answer 6

If the metal has been galvanized, it is coated with zinc, which will rust before iron because zinc is more reactive than iron. Once the zinc is gone, then the iron will begin to rust. So, the galvanization process extends the life of something mostly made of iron.

Answer 7

NO it doesn't from what I know

Actually it does but its zinc coating makes it take longer zinc is to protect it without the zinc it would instantly rust

Answer 8

Yes, after the corrosion of the sacrificial zinc plate (white rust) in a given localized area of the sheet that area will then begin to red rust (iron corrosion).

Answer 9

Yes. Galvanising is coating the steel with a substance that is less prone to corrosion. Usually zinc. Grinding would remove the zinc and expose the steel to the atmosphere.

Answer 10

Yes - where there are breaks in the tin.
