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 she ets. 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 an d spacing mat erials sho uld 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 imme diately 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 the Bulk Feed Tank. Check the
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. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
6. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of
the bin.
7. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of
the tank.
8. Drift punches can be used to align holes.
9. All vertical sidewall sheet seams must be overlapped in the same direction.
10. Close hole spacing 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 drainage
should be provided to prevent water collecting under or around the tank. Naturally, the site must allow
convenient access for easy loading and unloading, plus 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
Tools
Tools recommended for assembly of Bulk Feed Tanks.
1. Assorted sizes of combination wrenches
2. Hammer
3. 3-12" Long drift punches
4. 1 Large flathead screwdriver
5. 1 Pair of slip joint pliers

How to use charts on this page:
The chart titled “body sheet chart” is for the reference when building the tank. This chart tells you how
many rings the specific tank must have. To read the chart you look up the tank size you wish to build
(an 18' diameter tank with 4 rings will look like BFT 18'-4 rings). The side labeled “gauge” will tell you which
body sheets to use. The sheets are color coded, all t hat needs to be done is to match the gaug e number
with the color. (Use sheet gauge color code chart.)
IMPORTANT: Number of rings shown for each tank size are maximums. (12' 60° Tanks have a 6 ring
maximum. 15' 45° and 18' 45° tanks have an 8 ring maximum.)
NOTE: Body sheets are color coded on edges for gauge identification.

6. Sidewall Assembly
Sidewall Erection
12'-21' Bulk Feed Tank
12'-21' Diameter 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. (Example, 2 0 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, assemb le the top ring first. Note ring
overlap detail as shown in Figure 6B.
NOTE: See Page 27 for proper gauges and color code chart.
IMPORTANT: The number of rings shown for each tank size are maximums. (21' 45° and 15 ' 60 ° tanks
have a 6 ring maximum. 12' 60° tanks have a 7 ring maximum. The 12' 45°, 15' 45° and
18' 45° tanks have an 8 ring maximum.)

Figure 6E
Figure 6F
IMPORTANT: BOLTING PATTERN BEGINS IN THE CENTER OF THE SHEET. When starting to
assemble the sidewall rings to one another. Be sure to start in the center of the sheets
and work to the outside edges (horizontal seams). This allows the sidewall sheets to draw
up evenly.
Figure 6G
Once you have selected the proper gauge material, begin assembling all sidewall sheets in the following
manner: Standing on the inside of the tank, place the left panel to the inside with the right panel to
the outside.
NOTE: The rope caulking is installed before each sheet is assembled. Wip e sheets clean where caulking
is to be applied. Apply caulking on each side of the holes in the vertical seams and also on each
side of the horizontal row of holes.
Using correct size bin bolt throughout, begin assembling sidewall sheet end to end (overlapping the same
way throughout) until the ring is completed. All body sheet bolts are to be installed with the bolt head and
its neoprene washer to the outside and the nut to the inside. Do not tighten bolts until all sheets are
assembled and form a complete ring. Remember to attach lifting straps at the bottom of the vertical seams
while bolting the sheets together. These straps, coupled to the jacks, will enable you to later elevate the
tank. Now tighten the bolts, in sequence, starting from the center and working to the edge in both
directions. This permits the sidewall sheets to draw-up evenly. Complete one ring and stop. You are now
ready to assemble the roof.

15' and 18' Roof Assembly Instructions
After completing first ring assembly, you are ready to begin roof construction. First, build a roof center
support to hold the peak ring in place at the proper height. A simple structure consisting of a sturdy cross
arm attached to a pole and supported by a platform or scaffolding will do. Stand the center support directly
in the center of the tank. The bottom of the peak ring should be 89-5/16" (2269 mm) above the foundation
on the 18' tank and 78-15/16" (2005 mm) above it on the 15' tank. These dimensions are approximate
ones used in BFT construction. Adjusting the center support height will ease roof erection. Refer to
accompanying drawings for details. Install six (6) roof reinforcement angles spaced equally around the
tank. Reinforcement angle edges are parallel with sidewall sheet and peak ring, see views “AA” and “DD”
on Page 43.
The reinforcement angles utilize every other hole in the peak ring. At the sidewall, there are twelve (12)
spaces between each reinforcement angle on the 18' tank and ten (10) spaces between each on the
15' tank. Next, “skin” the roof by installing the roof panels on the just completed reinforcement structure.
Reinforcement angles will share all roof panels holes, including hole where pane l and pea k ring attach.
Ensure that all roof seams are caulked and lapped correctly as shown in the accompanying detail drawings.

Raising the Roof
NOTE: See 30° roof manual (PNEG-1092) in roof hardware box for instructions on 12', 15', 18' and
21' grain bin roof.
Figure 7AB
Anchor Tank Before 2ndRing Assembly
Anchor all jacks securely with metal stakes and cables (use one jack per sidewall sheet). Now raise the
tank just enough to assemble the next ring. When lifting the tank crank all jacks at an equal rate. This will
prevent bowing previously assembled rings and make for easier hole alignment. To the inside of the first
ring bolt the next ring. Be sure to stagger the sheets and select the proper gaug e material. Lower the tank
on the foundation after assembling and tightening bolts on each new ring. Now re-bolt lifting straps t o the
lowest ring in place thus far.
NOTE: Add outside ladders and other accessories to tank walls as you continue to raise the tank.
After body sheets are assembled and bolts are tightened, raise the tank and attach the legs. Do not put a
bolt in the bottom sidewall hole yet, because the hopper must be attached here. When the legs are in place
and tightened, release the jack enough to rest the tank on the legs.

Hopper Sheets
When starting to attach hopper sheets to sidewall it is recommened that the first hopper sheet seam be
positioned halfway between leg positions. Lap the hopper sheets as shown in Figure 8D and Figure 8G
on Page 48. Use two (2) strips of caulking on all seams at sidewall to hopper and hopper sheet to hopper
sheet. Use 5/16" x 1-1/4" bin bolts (head to outside of tank) for att aching hopper sheets to bottom sidewall
sheet. Use truss head bolts to attach hopper sheet to hopper sheet. Be sure to place the head of the truss
head bolt on the inside of the hopper. Leave one hopper sheet out to allow room to install the hopper collar.
Be sure to use two (2) strips of caulking between hopper collar and hopper sheets, then put last hopper
sheet in place. After the collar is in place, attach the hopper braces and tighten all bolts.

10. Ladder
Start attaching ladder at the eave (top) of the Bulk Feed Tank. After the first ladder has been attached to
the sidewall of tank, attach ladder extension rails to the ladder as shown in Figure 10F. Refer to Page 61
for proper ladder placement in relation to the eave of the tank. Use hex head bolts on all safety cage
connections. Attach hoop brackets and adjustable safety cage brace to the top of the extension rails.
Be sure to attach the adjustable brace on the left side of the ladder. Now attach the opposite end of the
adjustable brace to the roof ladder rail. After completing this, drill two (2) 5/16" holes through the adjustable
brace and use 1/4" x 1-1/2" bolts and nuts to secure the two (2) braces together.
Add the safety cage hoops to the brackets and attach vertical supports to the hoops. Continue adding
ladder sections and safety cage as sidewall rings are attached. Included in the safety cage package are
two (2) bell hoop halves (See Page 61) which should be located at the bottom of the safety cage. Follow
all drawings and details for proper placement of parts and proper location of safety cage.

WARNING
Make sure there is enough clearance between the tank and surrounding power
lines, electricution may occur.
WARNING
All usual and customary precautions must be taken to ensure safety of personnel
and property.
Raising Bin to Set on Foundation
Be sure that all bolts are tightened properly. The Bulk Feed Tank can now be set up on foundation. A crane
of adequate capacity attached to a spider assembly with cables connecting at each vertical sidewall seam
just above the legs will usually do the job. Reference a qualified rigger.
Anchoring Tank
Check all legs to see if shims are necessary to level the tank properly (shims are to be obtained locally).
After Bulk Feed Tank is level and shimmed properly, anchor the tank down with 5/8" washers and nuts.
(See Figure 11A.)

Roof Panel
Identical pre-punched roof panels are available from GSI for inlet and outlet sections of pneumatic fill
systems. Extruded lip of the panels provide for weather-tight installation. Caulking placed between angle
rings virtually eliminates all leakage problems. Rubber seal must be utilized at roof cap area to prevent
material “blow by” from pressurized systems.
To install fill kits in roof panels not pre-punched, cut 5-5/8" (143 mm) diameter holes in opposing roof
panels as shown
Refer to “peak ring seal strip” installation procedure when installing pneumatic fill kits.
Abnormal pressure may require us of optional “Cap Hold-Down Package”. (BLK-10474)
