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) willdevelopwhen closelypackedbundlesof galvanized material, suchas 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. Build one ring of sidewall sheets, making sure to caulk all seams.
2. Install the center collar tower support in the center of the bin.
3. Install eave clips and intermediate eave angles to the sidewall sheets. (Note how these are aligned.)
4. Install roof panels.
5. Install roof flashing.
6. Install peak cap.

3. General Overview
16 PNEG-2048 48' Diameter Unstiffened Bin with Special 6K Roof for IDC
Guidelines for Construction Procedures and Lifting Jack Usage
1. Before constructing the bin, consider the location of the door and other accessories. Proper
placement of lifting jacks in relationship to anchor bolts could make a difference on odd or even ring
bins. Walk-through door is centered between two (2) stiffener anchor bolts. The sidewall sheets are
also staggered 1/3 from end to end.
2. Anchor all jacks securely with metal stakes and cable.
3. Raise the bin just high enough to assemble the next ring. When lifting the bin, crank all jacks
equally. This will prevent bowing the previously assembled rings and make for easier hole
alignment. (See Figure 3A.)
Figure 3A Lifting Jack
4. Bolt the next ring to the inside of the first ring. Be sure to stagger the sheets and select the proper
gauge material.
5. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
6. Re-bolt the lifting straps to the lowest ring in place thus far. Continue ring additions until ready for the
door installation.
NOTE: 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 indoubt, use one jack on every vertical seam. Be sure to use heavy duty jacks
for commercial installation.
NOTE: Add inside and outside ladders to bin walls as you continue to raise the bin. (Refer to the manual
supplied with the ladder.)

3. General Overview
PNEG-2048 48' Diameter Unstiffened Bin with Special 6K Roof for IDC 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 48' 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 sidewall attachment detail and specific gauge sheet for the bin. The decal sheets are
located in the top ring. They are to be spaced evenly around the diameter of the bin.

4. Foundations
Foundation Recommendations
These are general foundation recommendations. Site conditions, system requirements and other factors
may create foundation construction requirements not covered by this manual.
Selecting the Proper Site Location
1. The selected site should be level, firm and free from underlying debris. The soil bearing capacity
should be equal to or greater than required by the footing specifications.
2. The concrete foundation surface must be level. If fill is required, it should be watered and tamped
thoroughly to prevent uneven settling from the weight of the bin.
3.Thesiteshouldalloweasyaccessforeasyloadingandunloading,aswellasprovideadditionalspace
for future units.
4. When selecting a bin site, also consider the positioning of handling equipment, fans, heaters, fuel
lines and the availability of electricity.
Scribe the Diameter
1. Determine the center of the foundation site and drive a small 2 x 4 into the ground to mark it. Drive
the stake into the ground so that it is the same height as the finished foundation will be.
2. Using one large spike, nail a straight 2 x 4 to the top of the center spike. This 2 x 4 should be
approximatelytwo feet(2') longerthan the radiusof the bin.Theswiveling2x4 will actasacompass,
enabling you to scribe the correct diameter of the foundation and later locate the anchor and stiffener
bolt locations. (See Figure 4A.)
NOTE: Making the 2 x 4 two feet (2') longer than the radius will allow the 2 x 4 to also be used as a
leveling device and for pulling concrete.

Foundation Forms
Circular foundation forms are commonly used for stiffened farm bins.
Figure 4B Circular Form
Preparing the Foundation Forms
1. Having scribed the diameter of the foundation, proceed by digging the foundation’s footing, which
consists of a large circular trench inside the foundation line.
2. Once the footing has been dug, you are ready to build the forms. The forms must be rigid enough to
hold their shape against the poured concrete.
3. The foundation must be flat. Sloped floors cannot be used in drying bins. A carpenter’s level placed
on top of the compass 2 x 4 constructed earlier will enable you to set the top of the forms to match
the top of the center stake.
4. Check the form work with a transit to ensure a uniform elevation for the entire foundation. The
foundation should be level within 1/8" on non-stiffened tanks and within 1/4" on stiffened tanks at bin
wall perimeter. Stiffened tanks must be shimmedlevel. Provisions for unloading system trenches, air
ducts, etc., should be made as required by the particular material handling system used.
NOTE: All foundation specifications shall be construed as recommendations only. Because of the
many variable conditions in an actual installation, manufacturer assumes no liability for
results arising from the use of such recommendations.
