Guidelines for Constructing the Sidewall Sheets
1. Before bolting the sidewall sheets together, check for the proper gauge of steel for the first ring.
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 and identify the various gauges of the sidewall with the color code chart given below and
begin building accordingly.
4. Assemble the top ring first.
Color Codes for Sidewall Gauge Identification
Refer to the below chart to identify the sidewall gauge based on the color code painted on the corners of
the sidewall sheets.
