I should have mentioned this in my original post: My plan is a 3-bay woodshed. Each bay will be 12 X 8...large enough for 4 chords...approximately 1 year supply. While burning the wood from one bay, the other 2 bays will have time to dry...resulting in 2 years of drying for each bay before I burn it. Anyway, this means I'm looking for a "flooring" system for a 12 X 24 structure. Everything I keep looking at is quite expensive.
