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.
