Sidewall Construction
Sidewall Construction Instructions
Gauge Color code
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 the various gauges of the bin with the color code chart and begin building accordingly.
REMEMBER..... Assemble the top ring first.
