(OP)
What notes do you use in your drawings for cold galvanizing due to field welding?
Something like this:
Field weld shall be repaired with Cold Galvanizing using blah, blah, blah...

It usually doesn't matter since its sacrificial. I just have that note on there so that the welded areas look pretty for the client right after installation.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Repair damaged galvazined coating due to field welding with a zinc-rich paint. Zinc-rich paints must contain either between 65% to 69% or greater than 92% metallic zinc by weight in dry film. The coating thickness for the paint must be 50% more than the surrounding coating thickness, but not greater than 4.0 mils (100um).
RE: cold galvanizing specs for notes for structural steel?
can somebody explain me why the gap between 69 to 92% is excluded (see above post) ?

I think the 65 to 69 is the zinc in the liquid paint, and the 92 is the zinc in the dry film. Depends on how it is measured.
