Sidewall Erection Instructions
Before bolting the sidewall sheets together, check that you have the proper gauge steel for the first ring.
The higher gauge numbers denote the thinner materials. (For example, 22 gauge material is thinner than
14 gauge.) In erecting most grain bins the thinnest material usually goes on top, therefore the first sidewall
ring you assemble will be the top ring of the bin. Check the various gauges of the bin with the color code
chart and begin building accordingly REMEMBER.....Assemble the top ring first.
Once you have selected the proper gauge material, begin assembling all sidewall sheets in the following
manner: Standing on the inside the bin, place the left panel to the inside with the right panel to the outside.
(See Figure 5A.) Check to see that the sidewall sheet is “Right side up”. Refer to Page 21 for details.
