Reno you bring up a good point about corrosion. I assume you guys know if you are shooting fasteners or attaching galvanized boxes to the new PT lumber it will rust off your nails, screws and straps. This stuff is tough on anything steel, galvanized or not. The green fasteners are OK but stainless is better. They originally said double hot dipped galvanized will work but I am hearing, "not so much", from my lumber supplier.
