Sidewall Erection Instructions
Gauge Color Code
1. 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, 20 gauge material is
thinner than 14 gauge.)
2. 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.
3. Check the various gauges of the bin with the color code chart and begin building accordingly.
REMEMBER..... Assemble the top ring first.
Overlapping Panels
1. Once you have selected the proper gauge material, begin assembling all sidewall sheets in the
following manner: Standing on the inside of the bin, place the left panel to the inside with the right
panel to the outside.
(See Figure 6A.) Check to see that the sidewall sheet is “Right Side Up”.
