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 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 immediately about ways to minimize
the adverse effect upon the galvanized coating.

2. Decals
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 n ot recommend
the use of downward flow systems (suction). Severe roof damage can result fro m any blockage of
air passages. Running fans during high humidity/cold weather conditions can cause air exhaust
or intake ports to freeze.
CAUTION!
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.

WARNING
DO NOT OVERFILL BIN. Stored grain, although heaped in the center, should
be no higher than the roof eaves at the outer edge. (See Figure 2A.) Filling the bin
above this point creates excessive internal pressure and may cause swelling and
eventual roof failure. The overfilling of a bin may also cause the blockage of roof
vents and eaves, which will lead to a build-up of air pressure causing roof damage.
(Based on grain with an angle of repose of 27°.)

Proper Decal Sheet Placement
Prior to beginning roof construction, it is necessary to build at least 1 ring of the bin.
Refer to the Bin/Silo construction manual you received with the bin. This manual will be packaged in the
sidewall hardware box.
Note for several of the lines (WS, FC and NS), the sidewall sheet has a “top” and “bottom”. It is imp ortant
to refer to these details.

4. Instructions
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.
WARNING
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 33' 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 se t fort h by th e manufa cture r.
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 wit hout
stopping, reduce the filling rate and drying air temperature so that th e stirrin g rate ca n 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.
8. The preceding steps are only general instructions which apply to the majority of stirring devices.
Since there are different manufacturers of these devices, it is importan t to read the operator’s manual
thoroughly for specific instructions applicable to the machine.

7. Farm Roof Assembly
Farm Roof Assembly
After completing the first sidewall ring, you are ready to begin construction. Begin with the center collar
sections. For convenience in opening and closing the center cover, the roof ladder and manhole sheet
should be placed directly opposite the two (2) slide rod holes in the center collar. Next build a roof center
support to hold the peak in place at the proper height. A simple structure composed of a sturdy cross
arm attached to a pole and supported by a platform or scaffolding will do. Stand the center support directly
in the center of the bin. The following dimensions are approximate distances used in bin roof construction.
Adjusting the center support height will ease roof erection. Place eave clips inside the bin wall to maintain
an opening around the top of the sidewall. This allows condensation, which normally collects on the
underneath side of the roof panels, to flow freely to the outside of the bin, thus avoiding possible
grain spoilage.

For best results in erecting the roof, install two (2) roof panels in four (4) places as shown in Figure 7C.
When these eight (8) panels are in place, the peak assembly should be centered. Next add two (2) or
three (3) panels at a time to each section making certain to la p them the same way, until all panels are in
place. Be sure the panels are bolted loosely. DO NOT TIGHTEN BOLTS UNTIL THE ROOF IS
COMPLETELY ASSEMBLED. When installing the roof panels, take into consideration placing the
manway for ease of access to and from the sidewall and roof ladders. On Stiffened tanks, particularly
on NCHT and FCHT series hopper tanks, location of the manway panel and roof ladder in relation
to the stiffeners is crucial for proper installation of the ladder system. Refer to PNEG-1451
for detailed instructions on NCHT and FCHT manuals and PNEG-1420 for flat bottomed
stiffened tanks (FCDL, NCL, WCL Series). These manuals are packaged with the ladder and
safety cage packages.
Fasten roof sheets to eave clips and sidewall sheets as you assemble.

Roof Assembly for 33' through 48' Roofs with Standard Peak Cap
NOTE: Additional instructions are given on the following pages for 42' diameter and larger farm bin and
commercial bin roofs. For 36' diameter hopper tanks (NCHT), refer to special instructions included
in the 36' NCHT manual.
After assembling the lower center collar “Z” ring, build a roof center support to hold it in place at the proper
height, as shown in Figure 7A and Chart on Page 26. A simple stru cture composed of a sturdy cross-arm
attached to a pole and supported by a platform or scaffolding in the center of the bin will be sufficient.
Place eave clips inside the bin wall to maintain an opening around the top of the sidewall. This allows
condensation, which normally collects on the underneath side of the roof panels, to flow freely to the
outside of the bin, thus avoiding possible grain spoilage.
Now you are ready to place the first group of roof sheets in place as shown in Figure 7C on Page 27. These
eight (8) panels will keep the peak assembly centered. Continue placing roof sheets (with a consistent lap
pattern) at intervals around the bin to distribute the weight evenly. DO NOT TIGHTEN BOLTS UNTIL THE
ROOF IS COMPLETELY ASSEMBLED. Once all roof sheets are in place and the bolts are tightened, the
center ring and flashing assembly may be placed on top of the panels. Place a flashing seam over a
“Z” collar seam to ensure correct alignment. Refer to Figure 7M on Page 34. The peak cap and slide rods
may then be put in place to finish the roof. On stiffened tanks, particularly on NCHT series hopper
tanks, location of the manway panel and roof ladder in relation to the stiffeners is crucial for proper
installation of the ladder systems. Refer to PNEG-1451 for detailed instructions on the NCHT series
and PNEG-1420 for flat bottomed stiffened tanks (FCDL, NCL and WCL series). These manuals are
included with the ladder and safety cage packages.

8. Support Ring Instructions
WARNING
DO NOT OVERFILL BIN. Stored grain, although heaped in the center, should
be no higher than the roof eaves at the outer edge. Filling the bin above this
point creates excessive internal pressure and may cause swelling and eventual
failure of the roof.
Ring Instructions
Be sure to install ladder rungs and safety steps as you assemble roof panels. (See Figure 8A.) At this
point you will have completed assembly of the roof. Do not tighten bolts yet. Optional equipment and
accessories should now be installed.
NOTE: When assembling such pieces as roof ladder rungs, use 5/16" x 1-1/4" bolts with a flat washer on
top of the slot and extra neoprene washer between the roof and the piece being added. This will
ensure a more protective seal against moisture.
IMPORTANT: Maximum weight to be supported and/or suspended from the roof is to be 6000 pounds
for 12' through 48' (non-trussed) ONLY.
IMPORTANT: Maximum weight to be supported and/or suspended from the roof is 10000 lbs. for
commercial (trussed roof) 39'-60' flattop roof bins. Roof loads should be supported from
the flattop or at the second lower “Z” collar.

8. Support Ring Instructions
Roof Support Ring Instructions 30° Roof
Roof support rings are standard on all bins up to 48' diameter. A single support ring is standard for
15' diameter bins. Two (2) support rings are standard for 18'-48' diameter bins. All support rings will be
placed on the outside of the roof panels.
To determine the location of the support rings, start at the narrow or peak of the roof panel and count
each hole. Having counted down the required distance, as described in the Chart below, install the
appropriate brackets.
Expansion bolts should be fully contracted when assembling support rings. When you have completely
assembled both rings, (but prior to expanding the bolts) tighten all roof bolts including eave clip bolts.
Now extend expansion bolts by running the nut out on the threads. This procedure should be continued
evenly around the roof until the ring raises the roof to show a slight crown.
Support ring expansion bolts may become dislodged from the ring during high winds or when the inside
pressure of the bin is too great. If one expansion bolt is dislodged, the entire ring will become useless.
To prevent this, drill holes through the support ring and expansion bolt (after the rings have been installed
and expanded to the correct size) and insert a cotter pin or bolt through each hole.
NOTE:
Welding of the expansion n uts to the pipe and expansion bolts or staking the expansion bolt
threads to prevent the movement of the jamb nut may be done as an option to drilling and pinnin g.

Support and Bridging Ring Instructions
Support rings, as shown on Page 39, are optional equipment. Support rings are optional for
54'-105' diameter tanks and 42'-48' tanks with a commercial roof.
To determine the location of the safety and bridging rings, start at the narrow or peak of the roof panel
and count each hole separately. Count down the required distance and install the appropriate brackets.
See Table on Page 39 for proper location.
Expansion bolts should be fully contracted when assembling safety and bridging rings. When both rings
are completely assembled, but are not yet expanded, tighten all roof bolts including eave clip bolts. Now
extend expansion bolts by running nut out on threads. This procedure should be co ntinued evenly around

1. Begin roof construction after assembling the two (2) top sidewall rings. Be sure the sidewall rings
are round.
2. Attach the top stiffeners and a 1 ring stiffener as shown on
The top stiffener bolts should be left loose. The roof stiffener bracket fits inside the wall stiffeners.
3. Install the eave clips as shown on Page 52. Every third clip should be located at a roof stiffener.
NOTE: The eave clip bolt and nut must be reversed (bolt head on the inside) at the top stiffener
for clearance.
4. Roof trusses should be assembled into complete rafters for installation. This should include the roof
truss sections, roof splices, truss channel brackets and roof stiffener clips. Tighten all splice bolts with
trusses positioned to create a straight truss. (Straight truss assemblies with tight connections will
prevent possible problems in later construction.)
5. After placing the “Z” collar at the correct center height, begin installation of the truss assemblies.
Attach a roof truss assembly to a roof stiffener bracket with a partially tightened bolt. Raise the top
of the truss assembly and bolt to the “Z” collar using 5/16" x 1-1/4" bolts (do not tighten the bolts at
this time). Be sure to use 5/16" washers on the slots in the truss clip. Complete bolting to the roof
stiffener bracket. The truss assembly must be stabilized at this point.
6. Place two (2) roof sheets on the truss assembly, one on each side of the rafter. The 5/16" x 1-1/4"
bolts in the “Z” collar must be removed and replaced through each roof sheet as they are positioned.
Use 5/16" x 1-1/4" bolts to connect the roof sheet ribs to the truss assembly. Be sure at least two (2)
5/16" x 1-1/4" bolts are placed in each roof sheet at the eave clip connections. These roof sheets will
stabilize the roof truss and center “Z” collar assembly.
7. Repeat Step 5 and Step 6 on the opposite side of the bin and then at the one quarter position
around the bin until four (4) rafter assemblies are erected with two (2) roof sheets each at four (4)
equally spaced positions.
Pages 43-46
NCL or
Pages 47 and 48

8. Connect the remaining rafter assemblies. Truss channels should be installed with each additional
rafter assembly. Tighten the bolts on one end of the channel with the channel positioned as close as
possible to the roof rafter splice. This will stabilize the truss assembly and hold it in a vertical position.
The screw jack (supplied with the 60' roof) or similar device may be needed to install the final truss
channels. Install the tension rods as shown in Page 52.
9. After completing the rafter system with all truss channels installed, the remaining roof sheets may be
bolted on the trusses. Be sure to install all roof ladder steps, intermediate eave clips and any other
necessary accessories.
10. Install the flattop as shown in Page 53. For bins with a dome cap option (which includes FCDL tanks),
the small center collar, roof flashing and roof cap assembly can be installed as a complete unit.
See Details on Page 35. Be sure to tighten all connections in the roof rafter system and related parts.

5. After placing the peak ring weldment (CRP-6096 (60') and CRP-6120 (54')) at the correct center
height, refer to Page 50, begin installation of the truss assemblies. Attach a roof truss assembly to a
roof stiffener bracket with a partially tightened bolt. Raise the top of the truss assembly and bolt to
the peak ring weldment using 3/8" x 1-1/2" bolts (do not tighten the bolts at this time). Be sure to use
3/8" washers on the slots in the attachment clip. Finish bolting the truss assembly to the roof stiffener
bracket. The truss assembly must be stabilized at this point. Attach the “Z” collar supports t o the peak
ring at this time. Align one of the bolted “Z” collar seams with the welded peak ring seam and rotate
the “Z” collar counterclockwise to the closest set of holes. The “Z” collar is to be loosely attached to
the “Z” collar supports. Make sure the roof sheets will align properly with the “Z” collar holes. It may
be necessary to field drill the “Z” collar to “Z” collar support holes to allow proper alignment of the roof
sheets. Refer to Page 60.
6. Place two (2) roof sheets on the truss assembly, one on each side of the rafter. Use 5/16" x 1-1/4"
bolts to connect the roof sheet ribs to the truss assembly. Be sure at least two (2) 5/16" x 1-1/4" bolts
are placed in each roof sheet at the eave clip connections. These roof sheets will stabilize the roof

the bin wall. The bottom rafter section (CRP-4759) will bolt into the stiffener bracket (CRP-5333).
7. The rafter packages will utilize the standard (PR-1874) splice plate but will have no purlins.
8. The upper rafter sections (CRP-5418 (27') (8.23 m), CRP-5373 (30') (9.14 m), CRP-5306 (33')
(10.06 m) and CRP-5274 (36') (10.97 m)) will be bolted into the center collar by use of the
clips provided.
9. Once the rafters are in place, field drill the holes to bolt the support angle ( CRP-5786 or CRP-57 87)
into the roof rafter (See Figure 11B on Page 66) and attach with 3/8" diameter bolts.
10. Attach the cable attachment bracket (CRP-5213) in the center of the support channel (CRP-5419 or
CRP-5285) as illustrated in Figure 11B on Page 66 and hang the cable.
11. If it is desired to support the cable from the flange of the support channel (CRP-5419), it will be
necessary to reinforce the flange with a 12" section of 3" x 3" x 3/16" angle.
12. No more than one cable should be supported from a pair of roof rafters.
13. This package will allow a maximum radius of: (27' equals 11.84') (8.23 m equals 3.61 m),
(30' equals 13.15') (9.14 m equals 4.01 m), (33' equals 13.31') (10.06 m equals 4.06 m),
(36' equals 14.49') (10.97 m equals 4.42 m). These radii represents the maximum radius that the cross
members will span. These are not recommended installation locations. Install according to the
temperature cable manufacturer’s recommendations. For a greater radius, the recommendation
shown in this manual for temperature cable installation must be used (using field cut, hot rolled
