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.
