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 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.

3. 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 not reco mmend
the use of downward flow systems (suction). Severe roof damage can result from any block age 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.

Before placing the support columns on the anchor bolts, use a transit and surveyor’s rod to locate high
and low areas in the concrete. To assure level alignment for the support columns, use the proper supplied
shim or shims between the concrete and base plate. After leveling is completed, place the support
columns over the anchor bolts, with shim plates underneath column. Next place HT-635 washer over
anchor bolts and loosely fasten with nuts and washers (not furnished). Refer to Figure 5A.

Begin assembling the hopper bottom by attaching a right and left pair or pairs of hopper panels to the
compression angle ring (3/8" x 1" bin bolt (S-455)) and discharge collar (1/2" x 1" hardware (S-4492)) at
four (4) opposing points as shown in Figure 5D. Caulking is required on the vertical seams of the lapped
hopper panels (Refer to Figure 5G). Splice plates which join the compression angle segments on the
back side may be installed following a pair of hopper panels. Refer to Figure 5F. Complete this assembly
by laying in alternate right and left panels moving around in one direction and lapping all sheets the
same way, See Figure 5E. Do not tighten bolts until all hopper panels are attached to each other, the
compression angle, splice plates and discharge collar.
On 15' through 24' tanks use 1/2" bolts on hopper seams.

7. Sidewall Assembly
Sidewall Erection Instructions
Before bolting the sidewall sheets together, make sure that you are using the proper gauge steel for the
first ring. The higher gauge numbers denote the thinner materials. (For example, 22 gauge material is
thinner than 14 gauge.) In erecting most grain bins th e thinnest material usually goes on top, therefore the
first sidewall ring you assemble will be the top ring of the bin, usually the thinnest gauge. Check the various
gauges of the bin with the color code chart and begin bu ilding accordingly. REMEMBER always assemble
the top ring first.
Figure 7A
Once you have selected the proper gauge material, begin assembling all sidewall sheets. Stand on the
inside the bin, place the left panel to the inside with the right panel to the outside.
NOTE: The rope caulking is installed before each sheet is assembled. Wipe sheet clean where caulking
is to be applied. Refer to Page 52 for caulking placement.
Using correct size bin bolts throughout, begin assembling sidewall sheets end to end (overlapping the
same way throughout) until the ring is completed. All body sheet bolts are to be installed with the bolt head
and its neoprene washer to the outside and the nut on the inside. Do n ot tighten bolts u ntil all sh eets are
assembled and form a complete ring. Lifting of sidewall should be done with jacks and lifting brackets on
the stiffener bolt holes.
(See Figure 7A.)
Decal Sheet Placement
NOTE: The decal sheets are located in the second ring from the top, evenly spaced around the diameter
of the bin.
Figure 7B 2 Post
PNEG-1070 15', 18', 21', 24', 27' and 30' CHT’s 43
8. Lifting Jack
Lifting Jack Usage
Always consider the location of the door and other accessories prior to erecting the bin. Proper placement
of lifting jacks in relationship to anchor bolts could make a difference on odd or even ring bins. Attachment
of lifting brackets should be made on the stiffener row of bolts. The sidewall sheets are also staggered
1/2 from end to end.
Figure 8A Anchor Jacks Securely
Anchor all jacks securely with metal stakes and cable. Raise the bin just high enough to assemb le the next
ring. When lifting the bin, crank all jacks at an equal rate. This will prevent previously assembled rings from
bowing and make for easier hole alignment. To the inside
stagger the sheets and select the proper gauge material. To avoid excessive pulling of the holes in the
sidewall, some stiffener lap and splice connections may go together easier if the sidewall is not tightened
until the stiffeners have been put in place. Lower the bin on the foundation after assembling and tightening
bolts on the new ring or rings. Next, re-bolt the lifting straps to the lowest ring in place thus far.
NOTES: Add inside and outside ladders to bin walls as you continue to raise the bin.
The number of lifting jacks required is best determined by personal experience. Factors such as
bin size, soil compaction, wind velocity, jack design, etc., should be considered when deciding
how many to use. If in doubt, use one jack on every other stiffener (one per sheet). Be sure to
use heavy duty jacks for commercial installations.

When installing bottom stiffeners, in some cases the stiffener with the base plate attached will not rest on
support structure. Shim plates have been furnished and should be used to fill opening between base plate
and compression element. See Page 65 for detail.
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.

Hoist Instructions
Recommendations for hoisting completed tank onto hopper bottom structure.
15. Hoisting
(All parts mentioned in this section are not
furnished.)
A crane is normally used to lift the tank and place it on top of the substructure. Technique of hoisting of
the complete tank on the hopper structure is in large part based on personal experience, equipment and
manpower. The following recommendations are intended as a guideline only.
1. Before lifting the tank, the following should be checked:
a. The columns and substructure should be checked for levelness and verified plumb and leveled
if necessary.
b. Final ladder and safety cage and door locations should be determined and clearance at these
locations verified.
c. Proper provisions should be made for safe working platforms around the top of the substructure.
2. Lifting techniques are largely influenced by personal experience and equipment capacity, however
general recommendations as follows:
a. Lifting brackets should be attached to the stiffeners. At least one bracket per sidewall sheet
should be used. These are usually attached in the third ring from the bottom of the tank. Brackets
should attach to a minimum of four (4) bolts through the stiffener. Attach cables to the lift brackets
and to the crane hook, which has been lowered through the center ring opening. Cables should
be sized to handle the entire weight of the bin. Make all lift cables of equal leng th befo r e the bin
is lifted. Refer to Figure 15A and Figure 15B on Page 76.
b. To prevent distortion of the assembled tank, a “spider” or horizontal bracing is recommended.
A suggested method of this is illustrated in the following details. This may be done by using a
center “hub” and pipe. The center hub is made of 6" schedule 40 pipe with 3" x 3" x 3/8" angle
welded to it and the pipe bolting to the hub. The second smaller pipe will bolt to the lifting brackets
attached to the stiffeners. (Refer to Figure 15C on Page 76.) Typical number of horizontal
members that should be used are shown in the chart below.
c. Use of temporary bracing across the peak collar may be needed to guide the cable. This should
be made easily removable.

3. To simplify the setting process, bend the sealing lip inward slightly to allow sidewall sheet clearance.
Bolt the sealing strip to the bottom of the sheet and apply final sealing. Typical sealing material such
as non-reactive silicon caulk should be applied. Shim between the bottom of the stiffeners and the
compression angle ring for level alignment if necessary.
4. After tank is secured, remove the spider or horizontal bracing and all hoisting attachments
and cables.
