Redstone industries specializes in heavy-duty, steel hoppers for all sizes of new or existing bins. We work directly with farmers and millwrights to improve your grain handling facilities. We also provide hoppers for industrial applications. Harvest has changed a lot in the last 100 years. Those big 18' bins your grandfather put up just don't get used much anymore. However, converted to a hopper bottom, they can easily be used for almost anything! A Hoppercone allows you to modernize and increase capacity of bins you already have.
