Hopper Bin Substructures


AGI substructures are design to support 15 ft. (4.57 m) diameter or 18 ft. (5.49 m) diameter farm duty hopper tanks respectively. Each substructure will support an (8) ring hopper tank with 45° outlet cone or a (7) ring hopper tank with 60° outlet cone.

AGI substructures are not designed to support commercial hopper tanks or any hopper tank supplied by another manufacturer.

All structural steel members are designed in accordance with the requirements set out by the 13th Edition of the American Institute of Steel Construction’s (AISC) “Manual of Steel Construction.” Loading conditions are in accordance with applicable portions of the American Society of Civil Engineers’ “Minimum Design Loads for Buildings and Other Structures” (ASCE 7-10)

The minimum design requirements for AGI structures are in accordance with the applicable portions of the 2009 International Building Code (IBC).


The following are standard AGI design loads:

For any load conditions exceeding those listed above, you must contact AGI for your substructure to be properly designed.

  • Optional ladder and platform packages available.
  • Structures available in either single bin or double bin configurations (double configurations for parallel drive thru only)
