Just in case my comment about Grainger hardware was less than clear - 
Grainger makes it clear if their part is *hot-dipped* galvanized or not.

The hot-dipped hardware that I've purchased from them is indeed high 
quality hot-dipped hardware, and seems to be priced like plated.

I'll note also that for a time Rohn supplied plated hardware with their 
towers. It may have been during the period when ownership changed hands, 
not sure.
