1. 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.
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!
The manufacturer does not warrant an y roof damage caused by excessive vacuum or internal
pressure from fans or other air moving system s. Ade quate v entilation and/o r “make up air” dev ices
should be provided for all powered air handling systems. The manufacturer does not recommend
the use of downward flow systems (suction). Severe roof damage can result from any blockag e of
air passages. Running fans during high humid ity/co ld w ea ther co nditio ns can ca us e air ex haust or
intake ports to freeze.

General Information
INSPECT the shipment immediately upon arrival. The customer is responsible for ensuring that all
quantities are correct. Report any damage or shortages by recording a detailed description on the bill of
lading to justify the customer’s claim from the transport firm. Our responsibility for damage to the
equipment ends with acceptance by the delivering carrier. Save all paperwork and documentation
furnished with any of the equipment/components.
This manual should be considered a permanent part of the equipment and should be easily accessible
when needed.
Read this manual carefully. This manual will provide instructions on building the sidewall. Other
instructions and manuals are required to build this tank. Some of the additional materials needed are
detailed below.
A stiffener and sidewall gauge layout chart is needed. If such a chart is not included with this manual,
contact GSI.
Roof instructions are required and must be followed. The roof construction manual (PNEG-1092) will
contain instructions for 60' diameter and smaller bins. See appropriate individual diameter instructions for
other diameters.
Ladders, roof stairs, roof handrails and other products are covered by separate instruction manuals.
Consult the appropriate accessory manual.
Aeration systems and transitions are to be installed according to the instruct ions provided with the system
or transition.
Anchor bolt placement details are provided in the GSI Concrete Recommendation Manual (PNEG-318).
Tools for construction:
• Combination wrench set 7/16" to 1".
• Alignment punches 12" long.
• Hammer.
• Screw drivers - standard and phillips.
• 3/8" Drive socket set and ratchet.
• 1/2" Drive socket set and ratchet.
• Nail aprons or tool pouches to hold supplies.
• Gloves for hand protection.
• Tape measure.
• 1/2" Drive electric or pneumatic impact gun.
• 1/2" Drive impact socket set.
• Lifting jacks.
• Center pole roof support.
• Step ladders.
• Large C-clamp or welding V-grip for clamping.
Quantities required depends on the number of workers and size of the bin/silo.
NOTE: The roof and top ring or two (2) rings will be installed prior to the beginning of bin lifting/jacking
procedures. Refer to all other procedures on sidewall and stiffener installation prior to the
start of construction.
1. Consider the starting location of the bin, as it relates to the location of doors and other accessories.
Proper placement of lifting jacks in relationship to anchor bolts could influence final locations. Note
that the sidewall sheets will be staggered.
2. 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 meet all 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.
Do not lift bins under windy conditions.
Follow the jack manufacturer’s recommendations on capacity and operations.
3. Lifting brackets must be attached through the stiffener bolt holes. Normally at least four (4) bolts per
stiffener are required.
4. Raise the bin just high enough to assemble the next ring. When lifting the bin, all jacks must lift at an equal rate. Monitor the process to ensure that even lifting is occurring.
5. Bolt the next ring to the inside of the first ring. Be sure to stagger the sheets and select the prope r
gauge material.
6. After assembling and tightening the bolts on the new ring (or rings), lower the bin onto the foundation.
7. Attach stiffeners to the body sheets every two (2) tiers on the external surface of the bin. Consider
leaving the sheets loose to make the attachment of the stiffeners easier.
8. Re-bolt the lifting brackets to the lowest ring in place thus far. Continue ring additions by repeating
Step 5 and Step 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.

Figure 3E As Viewed from Outside
Apply one strip of caulking near the outside edge of the outer sheet. (See Figure 3E.) Place a 10" long
strip of caulking along the horizontal seams. Before bolting the next ring into place, apply a strip of caulking
10" long on the front of the underlapped sheet at each joint. A 10" strip of caulking is also to be placed
along the lower horizontal edge of the lapping sheet at every vertical seam. This will fill the space that
occurs between the holes caused by the overlapping sheets. Additional 10" strips of caulking must be used
to fill larger gaps that occur with heavier gauges and laminated gauges.

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.
WCL tank stiffeners will be mounted on the outside of the tank.
The non-offset stiffeners that splice with a splice plate, must not overlap. Contact GSI if overlapping is
observed during construction.
When installing bottom stiffeners, the stiffener with base plate attached may not rest on the foundation
(due to unlevel foundation, etc.). If this happens, use the shim plates that are pro vided to fill any openings
between the base plate and concrete.

Installation and Management of Sidedraw Systems
GSI designs and manufacturers bins to the highest standards, however proper installation and good usage
practices for a commercial flume system are essential, regardless of manufacturer. Th e 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 unloaded through the sidewall without
installation of such a system and permission of the manufacturer.
Installation of a flume system may require installation of additional wind rings and 1" diameter anchor
2.
bolts. Refer to tank gauge sheet for wind ring placement or contact GSI.
for 1" anchor bolt usage.
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.
Refer to Chart on Page 46
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 sidedraw 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.

Sidedraw System Installation
Wind Ring Installation
1. Sidedraw systems may require additional wind rings. They will need to be attached at the
beginning of assembly because they go on the upper most rings. (See Wind Ring Requirements
Chart on Page 48.)
2. Attach the wind ring pipe to the stiffeners using 3/8" x 1" bolts through the flange of the stiffener.
(See Figure 6A.) In some cases field drilling of wind ring locations may be required.
3. Attach wind ring pipe section to the stiffener using two (2) 3/8" x 6" (S-7248) wind ring clamps.
(See Figure 6A.)
4. 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 nuts. Couplers should be centered on the seam of pipes.
Use the above chart for the installation of a single standard sidedraw system at the standard discharge
location in a WCL 2 post per sidewall (ex. WCL48-15O) tank. For multiple systems or special locations,
consult with GSI.
Refer to the gauge sheet supplied with the tank for the placement and number of wind rings on the tank.

Sidedraw System Installation (Continued)
Locating Chutes
1. Starting from the first row of holes in the top sheet, measure down the “starting distance” for the bin.
(See Sidedraw Chute Chart on Page 50.) (See Figure 6C on Page 50 andFigure 6D below.)
2. Keep adding the required number of chutes, making sure to leave 8" between the chute bolt holes.
(See Figure 6C on Page 50.)
3. Stagger the sidewall sheets on three (3) post stiffened tanks to create a vertical strip between
stiffeners free of vertical seams. Install the chutes between the stiffeners in this area.
Locate Discharge Opening
1. The last bolt hole in the chute should line up with the center of the discharge chute opening that is to
be cut. (See Figure 6E.) Approximate an opening by measuring 9-1/2" above and below the last bolt
hole of the chute. Mark horizontal cut lines.
2. To find the vertical center of the chute opening, measure over 11" to the right and left of the chute
bolt rows. Mark center point. (See Figure 6E.) Measure 7" from the center point on both sides and
mark vertical cut lines.
3. Cut opening where marked, making sure corners have a minimum of 1-1/2" radius. (See Figure 6E.)
1. For proper watershed, make sure that the upper side sheet overlaps on top of the sidedraw
weldment. (See Figure 6F.)
Figure 6F
Caulking
1. To seal the sidedraw weldment to the sidewall sheets use: two (2) b eads of caulking, one bead of
caulk on each side of the outside row of vertical bolts. Use discharge tube weldment as a template
to field drill the bolt holes through sidewall sheet. Use 3/8" bolts and nuts provided to bolt sheets
together See Figure 6G and Figure 6H. Use supplemental caulk as necessary for sealing purposes.
