Gt-4

[nialusa]

Errr, come on, think about it for a while, there is a big difference between a galvanised pipe and a body panel, there are different methods of galvinising something aswell, Audi have been galvonising cars for years before they started using aluminium.

A snip taken from an Audi sight

- It was the first Audi to have a fully galvonised body, leading to a 10 year Guarantee against corrosion,

oh no im not debating or disagreeing, all floorboards and panels are coated, but the whole body is not made of a galvansied product...it would wegh alot if it was...the audi is but the gt-4 isnt... still tho its not a guarenttee against rust

the audi that is galvanised is brand new i presume...tehe gt-4 was made over 10 years ago

It was talking about the Audi 80 in 1988 - 17 years ago

k...hen i was wrong about the audi, but the entire body and chassis is not galvanised, the car would be insanley heavy if it was... it is powder galvanised coated but it is not made of galvinised metal...as i stated something galvanised that fits in your hand weighs about 5 pounds, imagine a car that was entierly galvanised

Heres a clip Toyota themselves -

Corrosion protection is high in priority on the current model with all body panels, including the engine bay and floor pan, being pressed from corrosion resistant galvanised steel. Three grades of this zinc plated material are used dependent on the corrosion risk involved

"being pressed from corrosion resistant galvanised steel. Three grades of this zinc plated material are used dependent on the corrosion risk involved"

you know what pressed metal is right? that means theres 3 layers of zinc PRESSED with galvanized steel...there basically coated with galvanised steel

[nialusa]

I know what pressed metal is, but you clearly dont. Pressing metal is just a way of forming the shape of a peice of metal and has nothing to do with the galavanising process.
Galvanising is done in one of two ways, either hot, or cold.

Hot galvanising is done by dipping the sheet metal into a vat of Zinc, and we are talking microns thick 1000th of a inch or less.

Cold Galvanising uses an electric current to ket the zinc particles to stick to the sheet steel, again only microns thick.

Both ot these methods can be done before or after the metal is pressed into shape.

Go and check out "How stuff works" and do at least a little research bud. Cause what you just posted was totaly incorrect, well almost totaly incorrect, no offence or anything

so that's galvanising... hmm so if my rotors are zinc plated, that means that they were galvanised with zinc?

[nialusa]

Yes. Almost all Galvanising is done with Zinc as it dosnt rust/corrode and it goes on very thinly, about 100th the thickness of a human hair.

[SigmaProjects]

yea, i know the reason for zinc plating (why i had the option added to my rotors), just didn't know that it's called galvanising.

[nialusa]

Not sure if Galvanising and plating are the same thing, would have to check up on that but i think they are very similar. I think plating uses the electronic method of applying the Zinc???

[SigmaProjects]

but i thought you said that's what cold galvanising is. "Cold Galvanising uses an electric current to ket the zinc particles"

[nialusa]

Platting and galvanising may well be exactly the same thing, I`ve not checked the in`s and out`s of platting and have only just learned the tech background on galvanising. Instead of going by what I said, how about looking for yourself and doing some research like I had to?? then you can tell us all what the difference is between platting and galvanising......if any!

[91 Celica St]

yeah but i took a metal shop calss in high school and the teacher had explained plating as one marterial is plated with another material...meh i guess knowlege is lost through the years
