Corroded galvanized bolts puzzle.....
(OP)
Dear all,
I got these three bolts that corroded after a few months of service.
You can see white rust on them. What's puzzling is that there were other galvanized products on site but only these failed. So that rules out the environment
what could have gone wrong with the galvanizing?
Coating thickness, moisture??
Thanks,
Herc.

Thickness, top coatings, cracks/adhesion problems, localized variation in corrodents... there are several variables.

Where have these bolts been installed? Would it be somewhere humid or somewhere that moisture could get in easily?
