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.

2. Safety
Construction Procedures and Lifting Jack Usage
NOTE: The roof and top ring or 2 rings will be installed prior to the beginning of bin lifting/jacking
procedures. Refer all other procedures on sidewall and stiffener installation prior to the start
of construction.
1. Consider the starting location of the bin, relative to the location of doors and other accessories.
Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final
locations. Note that the sidewall sheets will be staggered.
2. The bin is lifted by the use of lifting jacks. Lifting jacks are used to slowly and evenly lift the bin during
construction. Lifting jacks must be properly sized and designed to carry all dead and live loads and
job site conditions associated with the construction of the bin.
The number of lifting jacks required is best determined by personal experience and expertise.
Factors such as bin size, jack design, construction conditions, support surface, etc., are all to be
considered when deciding how many to use. If in doubt, use one jack on every sheet. The lifting jack
must be adequate to carry all loads. Heavy duty jacks, generally hydraulic or electric powered in the
case of large bins, should be used for commercial installation. All jacks should be secured with
braces or otherwise maintained in a stable condition.
Lifting of the bins should not be done under windy conditions.
Follow the jack manufacturers recommendations on capacity and operations.
3. Lifting brackets must be attached through the stiffener bolt holes. Normally you will need to attach to
at least four (4) bolts per stiffener.
4. Raise the bin just high enough to assemble the next ring. When lifting the bin, all jacks must lift atan equal rate. Monitor the lift to ensure even lifting is occurring.
5. To the inside of the first ring, bolt the next ring. Be sure to stagger the sheets and select the proper
gauge material.
6. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
7. Attach stiffeners to the body sheets every two (2) tiers (on the external surface of the bin). You may
want to leave sheets loose to make the attachment of the stiffeners easier.
8. Now re-bolt the lifting brackets to the lowest ring in place thus far. Continue ring additions by
repeating Steps 5and 6.
9. Add inside and outside ladders as you continue to raise the bin. (Refer to the manual supplied with
the ladder.)
10. Lower the tank and secure to the foundation before leaving the job site.
11. At the completion of the tank, set stiffeners over the anchor bolts and measure the tank to ensure it
is in a round condition. Consult with GSI for questions on tolerances.
NOTE: For 2 ring doors or vehicle traffic doors special placement issues may apply. Consult the special
instructions provided with 2 ring doors or vehicle traffic doors for these options.

provided for the roof rafter wall attachment bracket in the roof assembly hardware. See the
roof instruction manual on those washers and their installation. All other sealing washers are
pre-assembled onto the bolts. Steel flat washers are shipped loose. In the shell portion of the bin
the 5/16" steel flat washer (S-845) is used where the base angle attach es t o the sheet and some
are installed at the main eave clips. The 3/8" steel flat washers (S-248) are used at the stiffener
splices and at the laminated stiffener to sidewall locations and steel flat washers are also utilized
in some roof locations.

Caulking Detail (Standard Non-Laminated Sheets)
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 7A. A strip of caulking 10" long, should be placed along the horizontal seams.
Before bolting the next ring into 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
overlapping sheets. Additional 10" strips must be used to fill larger gaps that occur with heavier gauges
and laminated gauges.

When bolting the two (2) assembled/laminated sheets to each other, apply one strip of caulking near the
outside edge of the outer sheet, between the outer two (2) rows of bolts and o utside the last row of bolts.
(See Figure 7D.) A strip of caulking 12" long should be placed along t he horizontal seams. Before bolting
the next ring into place, apply one strip of caulking 12" long on the front of the under lapped sheet at each
joint. Also, a 12" strip of caulking is to be placed along the lower horizontal edge of lapping sheet at the
vertical seam. This will fill the space that occurs between the holes caused by the overlapping sheets.
Additional 12" strips must be used to fill larger gaps that may occur with thicker gauges.
When assembling two (2) sheets to make a laminated sheet assembly, apply a row of caulk all around the
vertical seam. (See Figure 7D.)

Base Angle Installation
On the lower edge of the final bottom ring, attach the base angle ring utilizing 5/16" x 1-1/4" bin bolts.
Before the bolts are tightened, push the angle tight against the bottom edge of the sheet. Before
lowering the bin, apply the optional mastic sealer to the entire underneath side of the base angle.
(See Figure 8A.) Next, lower the bin onto the foundation and check for an adequate seal. If base sealer
strip is not used some other method should be utilized to seal the base ring to the concrete.

When installing bottom stiffeners, you may find that in some cases the stiffener with base plate attached
will not rest on the foundation (due to unlevel foundation, etc.). Shim plates have been furnished and
should be used to fill opening between base plate and concrete.
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.
NOTE: Some colors are different than those used for sidewall sheets.

Sidedraw Systems
Installation and Management of Sidedraw Systems
Grain systems designs and manufactures bins to the highest standards, however proper installation
and good usage practices for a commercial flume system are essential, regardless of manufacturer.
The following practices address general usage and installation criteria for such systems.
Sidedraw Installation
1. Side discharge is only permitted in GSI commercial bins when a GSI manufactured sidedraw flume
system has been installed. No corrugated steel bin should be unload ed through the sidewall without
installation of such a system and permission of the manufacturer.
2. Installation of a flume system may require installation of additional wind rings and 1" diameter anchor
bolts. Refer the tank gauge sheetfor wind ring placement or contact GSI. Refer the 1" anchor bolt
usage on Page 83.
Installation of multiple systems may require additional wind rings and must be placed a minimum of
90° apart. Installation of multiple systems requires approval of GSI.
3. A sidedraw should not be the only discharge system available. A standard center discharge and
conveyor should be installed.
Sidedraw Management and Usage
1. Sidedraw systems are intended for use with dry flowable grain. Sidedraws are not to be used for
poorly flowing products. This is not unique to GSI bins and flume systems but is a general rule for
such systems.
2. In multiple system installations, only one sidedraw may be used at any one time.
3. Filling should not be occurring at the same time as grain is being withdrawn through the sidedraw
flume system.
4. Prolonged storage of grain in the sloped condition produced by sidedraw discharge may accelerate
differential settlement and result in deformations of the bin/silo. After using the sidedra w system the
sloped grain should be returned to a near level condition by use of the center discharge. Leveling of
the grain should also allow more even consolidation of foundation and fill soils and produce more
even settlement of the bin/silo.
5. If geotechnical investigations or past experience indicate significant foundation level soil variations
or a site propensity toward differential settlement, sidedraw usage may be prohibited or severely
restricted. In this situation the use of a flume system should be reviewed with geotechnical
consultants or the foundation engineer.

Wind Ring Installation
Tanks that use wind rings require 2-3/4" diameter holes passing through the sidedraw chute; with the
center no less than 6" from either end and 4-3/8" from the sidewall. The wind ring must penetrate th rough
the chute and form a complete ring. Do not locate wind ring in 8" space at chute entrance. Field drill
stiffeners for wind ring attachment brackets (if required).
Discharge Tube Installation
1. Use the bottom two (2) holes in the last chute to locate discharge tube 28" below the 7th
horizontal seam. Refer to Figure 13A on Page 85 and Figure 13E on Page 89 for sidewall sheet
hole dimensions.
2. For proper water shed, install plate so upper body sheet overlaps the plate, as shown in Figure 13D
on Page 88 and Figure 13F on Page 90.
3. Use discharge tube assembly as a template, drill all holes 7/16" diameter.
4. Use two (2) beads of caulking to seal discharge plate to body sheets. Use 3/8" bolts and nuts
provided to bolt discharge assembly to body sheets.
