OK fellas, there is a product put out by US PLASTICS. www.usplastic.com called Dynaform. It is a pultruded polyester/fiberglass product in Ibeam tube or box section in  dimensions up to 8x8 or 8x4 in the Ibeam. I know it is moving away from lumber but if the beams are strong enough, the rot issue goes away as do many many hours of construction time and future maintenance. The price they have for the 8x4  Ibeam is $34.00 per foot with up to 15% discounts depending on amount.  It is not cheap but if you look at the labor, materials etc in building the  beams either in foam sandwich or lumber/epoxy it may be attractive.

They also have food grade storage containers and 5 gallon +  portable water containers and tanks. It is a very good site for many useful storage solutions.
