Sidewall Erection
12'-21' Bulk Feed Tank
12'-21' Diameters Bulk Feed Tanks are designed to be built vertically utilizing bin jacks or a crane of
adequate capacity. Before bolting the sidewall sheets together, check that you have the proper gauge
steel for the first ring. The higher gauge number denote the thinner materials. For example, 20 gauge
material is thinner than 14 gauge. In erecting all Bulk Feed Tanks the thinnest material always goes on
top, therefore the first sidewall ring you assemble will be the top ring of the tank. Check the various gauges
of the tank with the color code chart and begin building accordingly. Remember assemble the top ring first.

NOTE: See Page 27 for proper gauges and color code chart.
IMPORTANT: The number of rings shown for each tank size are maximums. (15' 60° Tanks have a
6 ring maximum, 21' 45° tanks have a 7 ring maximum. 12' 60° Tanks have a 7 ring
maximum. 15' 45° Tanks have an 8 ring maximum. The 12' 45° and 18' 45° tanks have an
9 ring maximum.)
