I was given a pile of boards just about what you have there. The boards that were given to me were something that were pallets for some kind for shipping?? First thing I found out about them is that what ever they were put together with was interior glue. Anything I used them for that was outside they just came apart. At the time I was building a building so I used them for the floor. The only problem I found was after the building was built that the thickness of each board was a little different from each other so they didn't make for a very good floor. The pictures and sizes just look a lot like what I had but who can tell from a picture so don't go by what I am saying. They are nice heavy duty boards and I am sure someone would have a use for them. I still have a few left over that I am trying to think of a use for.
