Large metal tanks or bins used to store grain. These bins are generally made up of individual panels that are bolted together. Unlike the standard grain bin, the stiffened grain bin generally uses upright steel bracing to stiffen the tank. This makes it possible to build much larger bins. The additional bracing is normally on the inside of the bin making it difficult to observer from the outside. The additional bolts that can be observed on the tank that are not on a seam are a good indication that the tank had been stiffened. The cost of the bin includes a concrete foundation that may have tunnels for aeration conveyor usage.
You can define the size of grain bins either by dimensions or by capacity. See the tables below for valid size ranges.
Define by Dimensions
The following table lists valid values for defining stiffened grain bins by diameter and height.

|---|---|
| 18 | 35 – 48 |
| 21 | 35 – 59 |
| 24 | 35 – 72 |
| 27 | 35 – 80 |
| 30 | 35 – 90 |
