These bins are engineered to eliminate the need for internal or external stiffeners. Engineers have designed the maximum strength out of every pound of steel to give you superior structural strength over the entire bin. That means a bin better equipped to handle the added weight of heavy snow loads, or the structural stress of extreme temperature conditions and high winds. The result is an extremely strong, expandable bin with on-farm sizes ranging from 1,850 - 72,720 bushels.
