2. Safety
Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If
moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the ground and vegetation. Any stacking and spacing materials should not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize
the adverse effect upon the galvanized coating.

4. General Information
Bulk Feed Tank Assembly Manual General Instructions
First, read the Assembly Manual completely before starting to assemble your Bulk Feed Tank. Check your
shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Mask may become difficult to
remove if left exposed to sunlight.
2. Vertical seams must be staggered on all sidewall rings.
3. When legs extend up 2 rings, the leg holes must be in alignment in the bottom 2 rings.
4. All hopper seams and the hopper collar use truss head bolts. The heads of the bolts must be on the
inside of the tank.
5. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of
the bin.
6. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of
the tank.
7. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
8. 7' Diameter sidewall sheets must be bolted together so there is 65-5/8" between leg holes.
(See Page 80.)
9. Drift punches can be used to align holes.
10. All vertical sidewall sheet seams must be overlapped in the same direction.
11. A hole spacing of 3-1/8" is used at the top of all top sidewall sheets and at the bottom of all bottom
sidewall sheets.
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The tank can be installed
satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the
foundation. The concrete foundation surfaces must be level
and tamped thoroughly to prevent uneven settling from the weight of the tank. Good water dra inage should
be provided to prevent water collecting under or aro und the tank. The site must allow convenient access
for loading and unloading and provide additional space for future units. Also, consider the positioning of
handling equipment, availability of electricity, etc.
. If some fill is required, it should be watered

How to use charts on this page:
The chart labeled “Sidewall Sheet Gauge Chart” is for the reference when building the tank. This chart tells
you what gauges your rings of the specific tank must have. To read the chart find up the tank size you are
building, for example, a 7' diameter tank with 7 rings is referred to as BFT 7'-7 ring. The side labeled
“Gauge” will indicate which sidewall sheets to use. The sheets are color coded, simply match the gauge
number with the color. (Use “Sheet Gauge Color Code Chart” below.)
NOTE: Sidewall sheets are color coded on edges for gauge identification.

Caulking is applied to all BFT parts before assembly.

Figure 6A Caulking Detail
NOTE: Rope caulking is applied before each sheet is assembled. Wipe sheet clean where it will be
applied. Apply caulking on each side of the holes of the vertical seams and on each side of the
horizontal row of holes.

6. Sidewall Assembly
Sidewall Sheet Orientation
IMPORTANT: Ple ase note sheet orientation when assembling the bin sidewall. The upper right corner will
have a slot or identifying sticker. This corner should be on the inside of the tank when
assembled. (See Figure 6C.)
Figure 6C
Sidewall Assembly
Start by assembling the top ring of the Bulk Feed Tank. The top row of bolt holes has 3-1/8" spacing in
the top ring. Before bolting the sidewall sheets together, check that you have the proper gauge steel for
the top ring. The higher gauge number denotes thinner materia l. For example, 20 gauge material is thinner
than 14 gauge. In assembling all Bulk Feed Tanks the thinnest material always go on top. The heaviest
corrugated sidewall sheets will be located on the bottom of the tank. Check the various gauges of the
tank with the “Sheet Gauge Color Code Chart” and “Sidewall Sheet Gauge Chart”, on Page 23. Begin
by putting the rings together on the edge of the sheets. After the first ring is complete, the roof must be
assembled as described on Pages 26-27. After the roof is assembled, the tank can be rolled on its side
for easier sidewall assembly. (See Figure 6F on Page 27.)
Tighten all bolts from the nut side only.

6. Sidewall Assembly
First ring assembly. Tighten
bolts from the nut side only.
Continue to add rings with lighter gauges first, then heavier gauges. Each subsequent row of sidewall
sheets goes to the inside of the previous row of sidewall panels. Remember to place the caulking between
every ring. See Figure 6D for illustration of proper sidewall overlap and caulking detail.
Be sure to stagger all vertical seams between rows.

6. Sidewall Assembly
IMPORTANT: Begin bolting in the center of sheets when connecting sidewall rings to one another.
When bolting sidewall rings to one another, always begin bolting in the center of the sh eet and work toward
the outside edges (horizontal seams). This allows the sidewall to draw up evenly.
Figure 6F Sidewall Assembly
It is easier to add more sidewall sheets with the tank on its side. It can be rolled easily from side-to-side
to allow the bolts and nuts to be put in the proper holes. NOTE: The roof must be assembled on the first
ring before rolling it over to its side. This will not be practical on taller tanks where jacks should be used.

7. Roof
Sealed Roof Panels Installation
NOTE: The roof and sidewall ladders are centered on a roof panel. Be sure to apply two (2) strips of
caulking on either side of bolt holes at the seams. Roof panel edges allow for the roof to be assembled in
either the clockwise or counterclockwise manner. (See roof sheet overlap detail on Page 29.) Be sure to
lap sheets in the same manner around the entire tank.
Figure 7A
On bins that will be equipped with a pneumatic fill system (See Page 72), the two (2) roof panels with fill
hole and exhaust hole must be located opposite each other on the Bulk Feed Tank. The peak ring may
now be installed.
