3. General Overview
General Information
General information, overview and instructions needed before performing work.
Read this manual carefully. This manual will provide instructions on building the sidewall and stiffeners.
You will also need to consult other instructions in building the bin.
These include, but may not be limited to:
1. A stiffener and sidewall gauge layout chart. If such a chart is not included with this manual,
contact GSI.
2. Roof instructions must be followed. Roof instructions are included in this manual.
3. Ladders, roof stairs, roof handrails and other products are covered by separate instruction manuals.
Consult the appropriate accessory manual. Inside ladder instructions are included in this manual.
4. Aeration systems and transitions are to be installed according to the instructions provided with the
system or transition.
5. It is critical that the anchor bolts are installed and spaced correctly.

3. General Overview
PNEG-4342 40-Series 42' Diameter Bin 15
Guidelines for Proper Storage of Grain Bin Materials Prior to
Construction
Storage of the build materials prior to construction is important. Do not to allow moisture to remain
between sheets or panels.
Wetstoragestain (rust) willdevelop when closelypackedbundlesof galvanizedmaterial,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.
Overview for a Typical Bin Installation
These are the typical steps one would perform when constructing a grain bin. Procedures may vary
depending on site requirements.
Pre-Assembly Activities
1. Sorting and grouping parts.
Assembly
1. For 42' bins, build 2 rings of sidewall sheets for even ringed bins or one ring for odd ringed bins and
12 rings, making sure to caulk all seams.
2. Install wind ring to help support the rings.
3. Install the center collar tower support in the center of the bin.
4. Install eave clips and intermediate eave angles to the sidewall sheets. (Note how these are aligned.)
5. Install roof panels.
6. Install roof flashing.
7. Install peak cap.

3. General Overview
16 PNEG-4342 40-Series 42' Diameter Bin
Guidelines for Construction Procedures and Lifting Jack Usage
The following procedure is a guideline when using the required lifting jack. Follow this general guideline
when lifting the bin as sidewalls are being installed.
NOTE: The roof and the top ring for odd ringed bins or the roof and 2 rings for even ringed bins, will be
installed prior to the beginning of bin lifting procedures. Refer to all other procedures on sidewall
and stiffener installation prior to the start of construction.
IMPORTANT: Begin building with the bin oriented for doors and material handling equipment to be in the
correct position when bin construction is complete.
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 bythe 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 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 should 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 at
an 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 Step 5 and Step 6.
9. Add inside and outside ladders as you continue to raise the bin. (Refer to manual supplied with
the ladder.)
10. Add platforms as you raise the bin. (Refer to manual supplied with the ladders and platforms.)
11. Lower the tank and secure to the foundation before leaving the job site.
12. 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.

3. General Overview
PNEG-4342 40-Series 42' Diameter Bin 17
Instructions for Stirring Devices
Bins are offered in more than one structural series for specific uses. To maintain the warranty, the
appropriate “series” grain bin must be used. Consult the sales catalog or contact the Engineering
Department for current recommendations. Note that the use of any stirring device with three (3) or more
vertical screws may require a heavier than “standard” series bin. Any re-circulating device or system
should be used in the “re-circulating” series bins. NOTE: For GSI bins larger than 42' diameter an
alternate method of mounting is to attach suspension chain to intermediate center collar.
1. Read owner’s manual for the stirring device and follow all instructions set forth by the manufacturer.
IMPORTANT: Install the switch for the stirring device near the roof manway opening so that the
unit can be observed while stirring.
2. Make sure there are no obstructions, such as protruding ladders.
3. After loading approximately 3' of grain, run the unit one complete revolution to determine if it is
working properly.
4. If the unit is functioning properly, operate the stirring device continuously while filling and drying to
avoid compacted grain around the vertical screws.
5. If it becomes necessary to stop a stirring device using laterally moving screws, try to stop it with the
vertical screws nearest to the center of the bin, away from the sidewall. Should a device stop or stall
for any reason and remain inoperable for any length of time, the auger carriage should be supported
to the grain surface before restarting. The vertical auger should be turned by hand, with a pipe
wrench, before power is applied.
6. For best results, fill the bin to one-half of the final intended depth. Dry grain to 16% and continue
filling. Use filling rates specified by stirring device manufacturer. If necessary to fill to the top without
stopping, reduce the filling rate and drying air temperature so that the stirring rate can keep up with
the drying rate.
7. Do not overfill bin. Filling should be stopped at bottom of top ring or 30" below the track.
NOTE: The above steps are only general instructions which apply to the majority of stirring devices. Since
there are different manufacturers of these devices, it is important to read the operator’s manual
thoroughly for specific instructions applicable to the machine.
Stirring devices may create additional loads on grain bin sidewalls, roofs and
floors. If high-moisture grain is loaded too deep and too fast, unstiffened bin
walls can become overloaded. Observe the following installation and operation
procedures if the bin is to be equipped with the stirring device.

Guidelines for Placement of the Decal Sidewall Sheet
Use the following as a general guideline the proper decal sheet placement.
NOTE: Refer to stiffener to sidewall attachment detail and specific gauge sheet for the bin. The decal
sheets are located in the first ring from the top. They are to be spaced evenly around the diameter
of the bin.

Anchor Bolt Charts
Prior to setting any anchor bolts, you must be sure to have the correct anchor bolt placement. Accuracy
is very critical for stiffener alignment during bin erection.
NOTE: Refer to proper chart to find the anchor chord dimensions that correspond to the bin that is
being built.
Scribe the radiuslocation ofthe anchor boltsby using a center stake and a straight 2x 4. Along thescribed
radius, start with one anchor bolt and work counterclockwise to locate one quarter of the anchor bolts then
clockwise to locate another quarter of the anchor bolts.Working off ofthe last anchor bolts in each quarter,
locate the remaining anchor bolts in the last two (2) quarters.
