I'm building a shed which sits on pressure-treated wood. I've got "Simpson Strong Tie CB44 4x4 Post Column Base" (at least I think that's the model number) in concrete, much like you'd do for a deck. It's all connected together with 5/8" bolts. I'd read that non-galvanized bolts are OK as long as the diameter is 1/2" or greater, so I used regular steel bolts.
I started on this project last year, and the foundation and pressure-treated base was exposed to the elements over the winter---it is rainy and foggy all winter here. Just for fun, I removed one of the bolts, and it had some rust---a lot more than I would have expected in less than a year. Is this a problem? Do people actually use those outrageously expensive galvanized bolts for things like this or not?
Btw, I don't think I'll make any changes at this point, since I assume the "post column supports" will decay before the bolts (although, strangely, they still look pristine). So, this is more just out of curiosity and/or for future reference. Thanks.
