If you read the trade rags for the construction industry, there are frequent articles are botu what type of fastners to use to nail treated lumber. Usually recommending stainless or coated fastners. Because the chemicals in the pressure treated lumber eat up plain steel nails.

The treated lumber on the market today is either ACQ (alkaline copper quaternary) or CA (copper azole) which contain much more copper than the old CCA (chromated copper arsenate). The problem with the new treated lumber is the copper content and how it interacts with other materials. Any two metals will have some kind of galvanic interaction, but the farther apart they are on the Galvanic Table (you don't want to go there), the worse the corrosion will be. The interaction between steel and copper is not good and should be avoided. Unless you have a coating that completely isolates the two materials, you are asking for trouble.

I just had the floor taken up in my trailer, and the supports were sandblasted & primed/painted. Is that enough protection between the new treated boards and the supports, or should I put it different boards? I can't afford Rumber at this point, but what about oak?
