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 bin.
These include, but may not be limited to:
• A stiffener and sidewall gauge layout chart. If such a chart is not included with this manual, contact
GSI.
• Roof instructions must be followed. Roof instructions are included in this manual.
• 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.
• Aeration systems and transitions are to be installed according to the instructions provided with the
system or transition.
• 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.
Start with one anchor bolt and work from it to the left to locate one quarter of the anchor bolts then to the
right to locate another quarter of the bolts. Working off of the last anchor bolts in each quarter, locate the
remaining anchor bolts in the last two quarters.

• Step ladders
• Large C-clamp or welding V-grip for clamping
NOTE: Quantities required will depend on the number of workers and size of the bin.
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 bun-
dles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of mois-
ture. 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.

Chapter 2: General Overview
Overview for a Typical Bin Installation
These are the typical steps one would perform when constructing a grain bin. Procedures may vary
depending on the different site requirements.
Pre-Assembly Activities
• Sorting and grouping parts
• Assemble A-frames
• Assemble center collar
• Assemble cap plate
• Install vent to roof panels
• Install wind ring bracket to the stiffeners
Assembly
• Build two rings of sidewall sheets for even ringed bins or one ring or three rings for odd ringed bins,
making sure to caulk all seams.
• Add top outside stiffeners and inside stiffeners at the same time to the two rings of sidewall sheets
(Note: These top stiffeners are the lightest gauge stiffeners and will get heavier as the bin is raised.
Therefore, the heaviest stiffeners are located at the bottom of the bin and are installed last.
• Install the wind ring to help support the rings
• Install the center collar tower support in the center of the bin
• Install the eave brackets to the inside stiffeners
• Install the eave angles to the sidewall sheets (Note how these are aligned.)
• Install the tension member or tension channels to the eave brackets
• Lift the pre-assembled A-frames, installing them in “opposite pairs” (across from one another) to bal-
ance out the load as you install
• Install the lower roof panels
• Install the upper roof panels
• Cut roof exhauster holes evenly spaced in upper panels
• Install the upper flashing
• Install the roof exhauster
• Install the flat top

Chapter 2: General Overview
Guidelines for Construction Procedures and Lifting Jack Usage
The following procedure is a guideline when using a lifting jack. Follow this general guideline when lifting
the bin as sidewall sheets are being installed.
NOTE: The roof and the top ring for odd ringed bins or the roof and two 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 equipment to be in the
correct position when bin construction is complete.
1. Consider the starting location of the bin, relative to the location of the doors and other accessories.
Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final loca-
tions. 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 condi-
tions 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 oth-
erwise 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 repeat-
ing 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 ladders and platforms.)
10.Add platforms as you raise the bin. (Refer to the manual supplied with the ladders and platforms.)
11.Lower the tank and secure to the foundation before leaving the job site.
12.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 two ring doors or vehicle traffic doors for these options.

Chapter 2: General Overview
Guidelines for Placement of the Decal Sidewall Sheet
Use the following as a general guideline for the proper placement of the decal sheet.
NOTE: Refer to the stiffener to sidewall attachment detail and specific 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.
Figure 2-2 3-Post Bin with three columns of stiffeners used on each sidewall sheet
NOTE: Dashed lines represent stiffener locations.
Sample Gauge Sheet
A gauge sheet should be supplied with every bin and contains important information specific to your bin.
The gauge sheet contains the specific details that are unique to your bin. You must reference this sheet to
know the correct order to install the sidewall sheets and stiffeners. The gauge of the sidewall and stiffeners
are marked with colors for identification.
It is important to use the correct hardware for each type of connection. The gauge sheet will identify what
hardware should be used in a vertical seam, horizontal seam, and an overlapping seam for each gauge.
The gauge sheet will also identify the sidewall rings where the wind rings must be installed.
Doors are to be installed in the ring or rings denoted with (D).
