Re: plywood drying.
Green products is not the only placer that makes marine ply, i guy i went to school with's (im a forester) dad owns a pole/ply mill which makes Marine plywood. Im not sure who thier buyers are but it is made here in SC and they are not greenproducts.com They do not use a kiln to dry B/c in the plywood process after they peel and cut the pieces to rough 4x8 they send it through a dryier before they lay them up and send them to the press. The only diff in the regular ply and Treated ply is the chemical. The treated wood goes to a vacumme chamber that pulls a vac. then the chanber is flooded with the chemical which is a water born chemical. So any way once treated the water in the wood from the process is what makes it wet and correct most places will not redry b/c of the money to do it. It has to be dried before treatment b/c the wood is already saturated and wood not soak up enough lbs. /cuft to be called marine ply. The two availible treatments are CCA (copper cromated Aresenate) (which in dimentional lumber was banned in the consumer market not commercial, like 20003or 04 (not sure about marine ply though) and ACQ (amoniacal copper quart) also a water born preservative like previously mentioned. This is (ACQ) the one that should not be in contact with steel or aluminum as it speeds up the corrosion process, like when used in deck construction the screws are special coated and will now say acq safe, i dont recall but think it is the quart part that is the corrosive part.
