Thought I'd share some practical experience of mine with ptl. In preparing our home for sale last fall I painted and atained the whole place, looked great....till around december when the behr stain started peeling from my deck and porch floors....
Issues keeping us from relocating left me with time to repair this peeling stain problem. Anyway where the stain did not peel it had been almost impossible to remove, tried most every chemical and mechanical option out there. Finally said, "frig this" got out the big guns and removed all the floor/decking and ran it through a planer ooooowwweee! better than new !! horray!! Well, that was when I noticed all my galvanized flashing and "simpson" hangers were badly corroded. Now this material was old style CCA treated the new ACQ treated I understand is even worse as far as the copper content which reacts with the galvinized metal parts. all of my ledger board flashing and many of the joist hangers were becoming compromised by this reaction. The ledger flashing led to some areas of rim joist damage. The only material unaffected by this reaction was the ptl. Consequently I replaced everything and this time used a Z-Max G185 rated galvanized hanger with copper flashing. Now I new this would of been an issue with the new ACQ treated but apparently the old CCA ptl is just as bad This deck was 11 years old.
Those thinking of bringing ACQ ptl from the mainland should also bring the G185 galvanized strong ties and copper flashing as well and either ceramic or stainless steel or double dipped galvanized nails/screws, that is, if you want to have things last.
Interestingly, HY-Bor treated material has no effect on these metal hangers/fastners So perhaps the lack of ptl is a blessing especially for the innocent DIY. Although I guess it should be treated with something where ground contact or wet exposure is an issue. I believe Carey suggested Jasco coating , in an earlier post when Hy-Bor is exposed to the elements.

We were lucky that we don't have large gatherings on our deck as in it's weakened state no telling what might have occurred.... Hello Prudential
