   I don't know if they discussed the chemical composition but there have been some threads over in breaktime about it,particularly about its corrosion of fastners

   Good research on corrosion of fasteners from Simpson

   Head over to Breaktime and get yurself an earful... IIRC it's a copper base composistion...  Most normal fasteners dissovle in 6 months or so.

   Most of the threads were on the older CCA. Do you have to use stainless steel. I have no idea where I am going to find stainless steel fence staples.

   The threads are for the newer ACQ and stainless it is. I don't use it for anything. I think my liability insurance would be tested to the max within a year after I installed the stuff. To many things to go wrong.

   Ask this question directectly over at BT or search under ACQ. Life is not a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming....                                        WOW!!!   What a Ride!

   Yes, it's called ACQ.

   And NO, you don't have to use stainless fasteners. You do need to be VERY careful when choosing fasteners, because the ACQ will indeed corrode most normal ones.

   If using nails, they must be either stainless, or hot-dipped galvanized.

   If using screws, be certain that the package clearly states that they can be used for ACQ-treated stock. The home centers are now carrying screws that are OK, and are not as expensive as stainless.

   (And yes, I'm one of the guys that normally hangs out over at Breaktime.)

   Unless you're the lead dog, the view just never changes.

   I wonder if there is enough copper in the wood  (probably as a sulfate salt) that  you get a reaction with the iron in the fastner to make iron sulfate. I think iron sulfate is soluable.

   I guess another mechanism would be corrosion due to a  voltage produced by the apposition of dissimilar metals. I think the same sort of think can happen if you solder dissimilar pipes together.

   What would happen with a fence stretched over the stuff isn't clear to me.

   Maybe I'll use that old stack of butt ugly locust posts.

   Hot dip lasts a little longer but it still corrodes.....

   Don't know about your deer, but the ones down here in Texas will easily jump a 5-6' fence. The ranchers usually put up 8' fences to keep them in. Might want to look at 10' "T" posts which are metal.

   FWIW - the CCA treated wood is still available - it can no longer be "manufactured" but dealers are still allowed to sell it - and from what I've read the new stuff is not necessarily a whole lot safer for certain applications - and your deer fence is probably one of them.  You might check around locally and be able to get a real good deal if you find someone who still has some - I know a lot of the places around here do.

   The way I heard it, last year in Fine Homebuilding magazine, is that when the ban fully goes into effect, CCA treated lumber cannot be sold for residential applications. It can still be manufactured and sold for other applications, agricultural, industrial, etc.

   But I could be wrong. It has happened before.

   In theory that's probably how it's supposed to work, but it is definitely still available in some "Do-It" center chains in my area - I'm guessing the Lowe's and HD probably won't have it.

   I think all of the other safety precautions still hold with the exception of the new stuff is supposed to be safe to burn."Well-behaved women rarely make history."from the Sweet Potato Queens' Book of Love
