Leesburg, Ohio | We are going to remove the corrugated floor from a 24' 6 ring butler bin tomorrow. It will be replaced with a new smooth plank aeration floor, but we will re-use the blocks now under the old floor. We are replacing the corrugated floor as we are moving the unload auger around the bin to line up with the dryer for additional wet holding. Since we will be cleaning this bin more than once a season now, we wanted a floor that's easy to sweep.
Metal stands are a pain, but are sometimes easier on a tall bin because of the large number of blocks needed to support the weight on a tall bin. If the concrete floor is not perfectly flat, some of the metal stands can fall out of place when the bin is empty/being unlodaed, and the floor will sag the next time it's filled. That said, most of our bins have metal stands.
For a correct answer to your specific question, you need to contact your local bin supplier's design engineer or salesman. It depends on grain depth, among other things.
FWIW, our local guy has advised us to use existing 12" blocks on edge (holes horizontal so air will flow thru) and put them end-to-end in rows on 2' centers, with the flooring planks laying across them (no wood involved).
