The manufacturer does not warrant any roof damage caused by excess ive v acuum 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
recommend the use of downward flow systems (suction). Severe roof damage can result from
any blockage of air passages. Running fans durin g high humidity/cold weather conditions can
cause air exhaust or intake ports to freeze.

Overfill Warning
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.

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 tank.
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.
Anchor Bolt Charts
Prior to setting any anchor bolts, you must be sure to have the correct anchor bolt placement. This is very
critical for stiffener alignment during bin erection.
NOTE: Refer to the proper chart to find the anchor chord dimensions that correspond to the bin that is
being built. (See Pages 15-18.)
Start with one anchor bolt and work from it to the left to locate one quarter of the anchor bolts the n to the
right to locate another quarter of the bolts. Working off of the last a nchor bolts in each quarte r, locate the
remaining anchor bolts in the last two (2) quarters.

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.
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. General Overview
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 equipmen t 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 by the 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 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.

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

Bolt Torque Specifications
The specification torque table below will help the installer determine how tight a specific bolt must be.
A bolt that has been over tightened can be just as dangerous as one that ha s not been tightened enough.
IMPORTANT: Bolts should not be tightened in excess of the torque specifications chart listed below.

Identifying Bolt Grades
Bolts are identified by grade (or hardness), the grade can be identified by the markings on the head of the
bolt. These markings will be in the form of slash marks and patterns. Use the following as a guide to
determine the correct bolt grade.
NOTE: Refer to 2.66" commercial tank bolting requirements for complete bolt usage.
