I went to check all of the lumber stores in Bismarck and Mandan in search for 5 sheets of 5 ply or 7 ply Marine plywood and no body carries them anymore and will not order them because they ll have to buy them in Units so my question is where can i find those  materials around here??

Thanks
Brian

do not use green treated in contact with aluminum.  it's very caustic.

This is what I have used in past. A boat that me and my dad replaced the floor 20 years ago with 3/4" green treated and then carpeted, still running strong today.

Green treat of 20-years ago is different than the green treat we have today. do not use green treated wood in any place that it will come in conact with aluminum. Actually, a better rule of thumb is not to use it on any boat, fiberglass or aluminum.

It does appear that the chemicals in green treated lumber changed about 10 years ago and should not be used for marine use, especially in aluminum boats. Here is a link to an older thread that discusses green treated for boat floors.

Thanks eyexer for that little bit of info.  I need to replace some of the flooring in my boat and was going to use green treated.  I learned something new today........now I can go fishing.

I was told by Wade from Dakota tackle that its a no no no to use green treated, Glad I asked around before I went further. I know a guy that works at Gibbons for 20 plus years so Will give him a call.

ten or twelve years ago the EPA passed new regulations preventing the use of formaldehyde in lumber treating.  The new chemicals are highly caustic to metals.  a non galvanized nail will disappear in one to two years.

For marine plywood, check with Marshall Lumber on the Strip between Bismarck and Mandan.  I walked in there a couple yeaqrs ago, and they had it in stock.

The new green treated lumber is called ACq or Menards calls it AC2, it is very toxic on all metal except stainless steel.

Do you mean to say the wood hurts the aluminum?  If so how bad?

  I have a friend that just put green treated plywood in an Alum. boat.   I had heard on FB in the past it is a no no.  I just can't remember why.

It could very easily eat a hole in aluminum in a matter of a few years.

More correctly acidic, not caustic. Caustic is an alkali chemical called sodium hydroxide and isn't generally corrosive to metals.

I don't know about that.  In all the building trade journals that I've read regarding the new treated lumber they always referred to it as being caustic.  But I"m no chemist,lol.

Yeah, I suppose by definition "caustic" means "corrosive", but I'm guessing (and only guessing because I don't know) the treatment is acidic, not alkali on the pH scale.

I guess technically that's probably true.

Technically, both acids and strong bases are caustic which is defined as "capable of eating away or destroying by chemical reaction".  Hence we stored them in plastic or glass containers when I ran a chem lab.

Here's a good little read on AC2 treated lumber.  http://www.midwestmanufacturing.com/MidwestManufacturing/web/docs/pdf/AC2BrochureFront.pdf

The part I found interesting was the talk on fasteners, apparently they think AC2 treated lumber doesn't need to have stainless steel fasteners unless it's used in a wet environment.  Guess what I thought odd about that is the question of "why the heck would I use treated wood for things I don't thing will be exposed to high humidity or water?

An important point to always remember with treated lumber of any kind is what's the express purpose in treating it.  And that is to kill micro-organisms that create rot.  Hence, all treated lumber is "toxic" and should be regarded as unhealthy to humans as well.
