New Product--We manufacture and sell a flexible galvanized skirt that wraps around bins. It moves with the bin when it expands and contracts. Bins no longer fight against and break the seal and ruin the grain. Instead, rain and snow melt glances off the skirt and concrete bin base.
This is a permanent fix. We've been testing for three years now. It is so nice not to have to chip and shovel rotten corn when we're cleaning bins out. All-Bin Flex Skirt (link)
