Galvanised bicycle frames?

Certainly a different look.
But why do that to good metal?

Perhaps you are just talking about "cold galvanising" with a paint
brush.

I've done a search on the 'net but didn't turn anything up on this topic.

Does anyone know anything about galvanising steel bike frames to prevent
corrosion?

Could be a ..different look. (If not painted).

What are people's thoughts?

I like the idea,
but for hot dipping, if you can find someone to do it, with so many thin
tubes it would be hard to empty them when it come out of the bath.(think of
all that extra weight 😉)
also it will need to be an all tig welded frame. most solder will melt in
the bath(about 445C). it will be things like cable stops, rack mounts,
bottle mounts and the rear dropouts that might be soldered. Cleaning up the
BB(and any other threads) could be a problem too.

Electro-Galvanizing might be a much better way to go. I dont know what they
will say about the solder(if there is any) and it will cost much more i
believe(it has been a long time since i priced stuff like this)

Perhaps there'd be issues with other metal components attached to the
frame.

fitting things like seat post and the head set could be a little tricky but
doable.
ring some electroplaters and get some prices
as always i could be wrong, hope i havent talked you out of it

what about chroming? is there also a heat issue too?
or can that be done by electroplating too ?

cheers,

I imagine that hot dipped galvanising might cause brazed fittings to
weaken. High quality steels tend to have less of a problem with rusting
anyway, it tends to be more cosmetic than structural. And in any case,
most people would still like to paint the frame to make it look nice.

chrome is electroplated. (there would be a heat issue with hot dipping
chrome, it melts at 1907C, steel melts around 1370C, see the problem 🙂 )
the killer with chrome is the prep, as i understand it, unlike paint chrome
doesn't cover dints and scratches. So the prep has to be spot on. if you
want a mirror finish you have to start with a mirror. it would also cost
alot more. (its first copper plated i believe, i wonder what that would look
like and how well it would last??)

if i am wrong its all googles fault

Satin chrome looks good without too much surface preparation needed. I have
a couple of 531 forks that I took unpainted to a local plater for satin
chroming to approximately match the brushed titanium frames on which they
were going. Several unobservant people have looked at the frame and the
forks and asked me if they are ti forks - at that point I point out the 531
stickers on the fork blades...
