You should consider the location of the bin site relative to power line locations or electrical transmission
equipment. Contact your local power company to review your installation plan or for information
concerning required equipment clearance. Clearance of portable equipment that may be taken to the bin
site should also be reviewed and considered. Any electrical control equipment in contact with the bin
should be properly grounded and installed in accordance with National Electric Code provisions and other
local or national codes.
This product is intended for the use of grain storage only. Any other use is a misuse of the product.
Sidewall bundles or sheets must be stored in a safe manner. The safest method of storing sidewall
bundles is laying horizontally with the arch of the sheet upward, like a dome. Sidewall sheets stored on
edge must be secured so that they cannot fall over and cause injury. Use care when handling and moving
sidewall bundles.
Personnel operating or working around equipment should read this manual. This manual must be
delivered with equipment to its owner. Failure to read this manual and its safety instructions is a
misuse of the equipment.
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 rema in 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.
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.
DC-969
CAUTION
GSI Group, Inc. 217-226-4421
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air” devices
should be provided for all powered air handling systems. The manufacturer does not reco mmend
the use of downward flow systems (suction). Severe roof damage can result from any block age of
air passages. Running fans during high humidity/cold weather conditions can cause air exhaust
or intake ports to freeze.

Use a transit and surveyors rod to locate high and low areas in the concrete, before placing the support
columns on the anchor bolts. To assure level alignme nt, use the proper supplied shim (or) shims between
the concrete and base plate. After leveling, place the support column s over the anchor bolts, on the shims
and loosely fasten with nuts and washers (not supplied). (See Figure 7A.)

The 36' hopper bottom has three (3) sections. Apply caulk to all hopper section seams as shown
in Figure 7H on Page 30.
Step 1: Attach all the top panels to the compression angles using bolts. See chart below for bolt
specifications. Install the compression splice plates on the back side of the compression angle.
(See Figure 7E.) All top panel overlap seams use 1/2" x 1" bolts. Lap all panels as shown in Figure 7F.
Step 2: Assemble the left and right sides of the middle section to the top sections that were just installed.
Use 1/2" x 1" bolts for all middle section seams. Use 1/2" x 1-1/2" bolts at the corners of the panels where
three (3) or more panels overlap. Lap all panels as shown in Figure 7F.
Step 3: Once the middle panels are installed the bottom hopper panels and discharge collar may be
attached with 1/2" x 1" bolts at four (4) opposing points as shown in Figure 7I on Page 30. Complete this
assembly by laying the remaining panels - moving around in one direction and lapping all sheets the same
way. Do not tighten bolts until all hopper panels are attached to each other, the compression ring, splice plates and discharge collar.
NOTE:
All bolts used in hopper assembly should be installed with the bolt heads to the inside of the hopper.

panels, splice plates and compression angle segments.
Install rack and pinion roller gate as shown in Figure 7J on Page 32, using 5/16" x 3/4" bolts.
When hopper structure has been completed, it should be level to within plus or minus 1/8" maximum
deviation, as compared to all other support columns as measured at the top to the compression angle ring.
The support columns must be plumb to within plus or minus 1/2" as measured from the top.
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, 22 gauge material is thinner than
14 gauge.) In erecting most grain bins the thinnest material usually goes on top, therefore the first sid ewall
ring you assemble will be the top ring of the bin. Check the various gauges of the bin with the color code
chart and begin building accordingly. REMEMBER assemble the top ring first.
Figure 8A

DSidewall Sheet
Once you have selected the proper gauge material, begin assembling all sidewall sheets in the following
manner: Standing on inside of the bin, place the left panel to the inside with the right panel to the
outside. (See Figure 8A.)
NOTE: The rope caulking is installed before each sheet is assembled. Wipe sheet clean where caulking
is to be applied. Refer to Page 34 for caulking placement.
Using correct size bin bolts throughout, begin assembling sidewall sheets 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 on the inside. Do n ot tighten bolts u ntil all sh eets are
assembled and form a complete ring. Lifting of sidewall should be done with jacks and lifting brackets on
the stiffener bolt holes.
Figure 8B Standard, Triple and Quad Punched Sidewall Sheets
as Viewed from Outside.
Apply one strip of caulking near the outside edge of the outer sheet and between the outer two (2) rows
of bolts, refer to Figure 8C. A strip of caulking 10" long, should be placed along the horizontal seams.
Before bolting the next ring in place, apply one strip of caulking 10" long on the front of the underlapped
sheet at each joint. Also, a 10" strip of caulking is to be placed along the lower horizo ntal edge of lapping
sheet at every vertical seam. This will fill the space that occurs between the holes caused by the
overlapped sheets. Additional 10" strips should be used to fill gaps that occur with heavier gauges.

Give some thought before starting the bin on location of door and other accessories. Proper placement of
lifting jacks in relationship to anchor bolts could make a difference on odd or even ring bins. Attachment
of lifting brackets should be made on the stiffener row of bolts. The sidewall sheets are also staggered
1/2" from end to end.
Figure 9A Anchor Jacks Securely
Anchor all jacks securely with metal stakes and cable. Now raise the bin just high enough to assemble
the next ring. When lifting the bin, 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 gauge material. To avoid excessive pulling of the holes
in the sidewall, some stiffener lap and splice connections may go together easier if the sidewall is not
tightened until the stiffeners have been put in place. Lower the bin on the foundation after assembling and
tightening bolts on the new ring or rings. Now, re-bolt the lifting straps to the lowest ring in place thus far.
NOTES: Add inside and outside ladders to bin walls as you continue to raise the bin.
The number of lifting jacks required is best determined by personal experience. Factors such as
bin size, soil compaction, wind velocity, jack design, etc., are all to be considered when deciding
how many to use. If in doubt, use one jack on every other stiffener (one per sheet). Be sure to
use heavy duty jacks for commercial installations.

between base plate and compression element. See Page 58 for detail.
IMPORTANT: If shim plates are not used where required, the downward pressure of the stiffeners will not
be transferred directly to the foundation and bin failure could result.

1. To connect wind ring pipe to the stiffeners, attach with 3/8" x 1" bolts through the flange of the
stiffener. In some cases field drilling of wind ring locations may be required. (See Figure 14A.)
2. Attach wind ring pipe section to stiffener using two (2) 3/8" x 6" (SS-7248) wind ring clamps.
3. Place pipes end to end without overlapping. Fasten together using two (2) wind ring couplers and
six (6) 3/8" x 1" flanged head bolts with flanged nuts. Couplers should be centered on the seam
of pipes.
Wind rings must be installed in relation to the ladder rungs as shown here, to ensure
compliance with O.S.H.A. regulations. (See Figure 14B.)
The shim plates should be used where necessary to ensure the base plates are firmly supported by the
columns. Use the shim plates to fill any gaps between the base plate and the compression weldment.
(See Figure 15A.) Attach the base stiffener to the stiffener column and compression weldment with
5/8" x 2-3/4" bolts (two (2) per stiffener). Place a washer on the top side of the stiffener base plate.
The 36' aeration package is installed through the sidewall of the bottom ring of the ho pper tank. An extra
sheet of sidewall is provided to reinforce the aeration opening. A platform for supporting the fan units on
the side of the tank is not provided.
Step 1: Install the two (2) extra sidewall sheets 180° opposite of each other in the location where the
aeration tubes are to be located.
Step 2: Using 18" reinforcement sleeve (SCHT-2458) as a template, mark hole in sidewall for cutting.
Locate hole 2" above compression angle. Do not locate hole on vertical sidewall seam.
Step 3: Using a torch or saw, cut the hole in sidewall sheets for tube.
Step 4: Install reinforcement sleeve in sidewall hole and weld in place.
Step 5: Insert elbow joint through sleeve and weld or screw in place as shown.
Step 6: Connect tube coupler to the tube with the clamp provided.
Step 7: Place tube with tube coupler in elbow and install angle hold-downs. Six (6) angles with
corrugated pieces welded on them are supplied for each tube (three (3) per side). Bolt
or weld each angle to the hopper sheet and screw or weld the corrugated material to the
perforated tube (#14 x 1" self-drilling). Weld or screw elbow joint to tube.
Step 8: Bolt or weld on angle ring for attachment of fan.
Step 9: Touch up any welded areas with a rust inhibitive type paint.

Recommendations for hoisting completed tank onto hopper bottom structure.
19. Hoisting
(All parts mentioned in this section are not
furnished.) A crane is normally used to lift the tank and place
it on top of the substructure. Technique of hoisting of the comple te tank on the hopper structure is in large
part based on personal experience, equipment and manpower. The following recommendations are
intended as a guideline only.
1. Before lifting the tank the following should be checked:
a. The columns and substructure should be checked for levelness and verified plumb and leveled
if necessary.
b. Final ladder and safety cage and door locations should be determined and clearance at these
locations verified.
c. Proper provisions should be made for safe working platforms around the top of the substructure.
2. Lifting technique are largely influenced by personal experience and equipment capacity however
general recommendations as follows:
a. Twelve (12) lifting brackets should be attached at the stiffeners. At least one bracket on every
other stiffener should be used. These would typically be attached in the third ring from the bott om
of the tank. Brackets should attach to a minimum of four (4) bolts through the stiffener. Attach
cables to the lift brackets and to the crane hook, which has been lowered throug h the center ring
opening. Cables should be sized to handle the entire weight of the bin. Make all lift cables of equal
length before the bin is lifted. (See Figure 19A and Figure 19B.)
b. To prevent distortion of the assembled tank a “spider” or horizontal bracing is recommended.
A suggested method of this is illustrated in the following details. This may be done by using
a center “hub” and pipe. The center hub would typically be made of 6" schedule 40 pipe with
four (4) 3" x 3" x 3/8" angles welded to it and the pipe bolting to the hub. The second smaller
pipe would bolt to the lifting brackets attached to the stiffeners. (See Figure 19C on Page 68.)
Four (4) horizontal braces are recommended.
c. Use of temporary bracing across the peak collar may be needed to guide the cable. This should

3. It will generally simplify the setting process to bend the sealing lip inward slightly to allow sidewall
sheet clearance. Once tank is in place, bolt the sealing strip to the bottom of the sheet. Shim between
the bottom of the stiffener and the compression angle ring for level alignment if necessary.
4. After tank is secured remove the spider or horizontal bracing and all hoisting attachments
1. Attach flashing to the bin wall using the pre-punched holes at 9-1/3" above the horizontal seam.
2. Attach left side of the first piece of flashing to the sidewall using the connection as shown in
Figure 20A. Working clockwise, overlap the flashing at the right hand hole of each piece of flashing.
NOTE:If bolts are installed at flashing seam location they will need to be removed.
3. At vertical seams attach flashing that is to span the vertical seams using both left and right holes.
Drill flashing holes from the outside of the bin through the sidewall sheet holes. Remove drilled
flashing and assemble vertical seam bolts and nuts. (See Figure 20C on Page 71.) Replace drilled
flashing and attach according to Figure 20B. Continue around the bin clockwise.
