I bought some hot-dipped galvanized nails for use in a project to build
an elevated walkway around the building shown here
http://www.davidillig.com/observatory15.shtml. (I'm moving the door
around to the back of the building.) I noticed right off that the
slightest off-center hammer blow would bend the nails I bought. I might
not be Tom Silva, but when I hit a nail with a hammer it usually drives
home. After too many bent nails I examined the nails. Where they bent
the zinc peeled off revealing aluminum beneath. I also noted that
hammer blows caused the nail heads to shed some zinc in nails that did
not bend.

What the ~!? I think these nails are sub-standard because they bend
easily and because the zinc can peel. They are not suitable for use in
today's pressure-treated lumber.

Comments? Experiences?

I might have noticed that the nails are lighter weight. Is there a reason
to galvanize aluminum nails. Aluminum nails do indeed bend easily. I's say
that what you got was not what you bought.
