2. Recommended Method for Full Floor Installation
Fan Placement Diagram
For uniform air flow, place the fans in relation to the unloading tube as shown in Figure 2A. Floor planks
should be perpendicular to the unloading tube.

2. Recommended Method for Full Floor Installation
Grain Systems Recommended Method for Full Floor Installation
Using the GSI recommended method for full floor installation should save construction time and
eliminate the problem of improper installation which could invalidate your warranty. Note the following
dimensions as shown in Figure 2B.
• Dimension “A” is the leg-to-leg spacing along the centerline of a given plank.
• Dimension “B” is the amount of stagger between supports under adjacent planks
and is half of Dimension “A”.
• Dimension “C” is the distance from the center of the unload auger to the nearest rows of
supports and is half of Dimension “B”.
Dimensions “A”, “B” and “C” are shown on the appropriate grandstand layout for wall heights under
32 feet. For taller bins, grandstand quantity as well as dimensions “A” and “B” are given on Page 23 and
Page 24 for 20 gauge.
1. Layout centerlines of tank. Make sure one centerline is in line with the direction of the flooring
planks while the other centerline is perpendicular with the flooring planks. See Figure 2B.
2. From the centerline that is perpendicular to the flooring planks, measure the distance of
“C” Dimension and mark a chalk line. See Figure 2B.
3. From the line chalked in the previous step, measure over the distance of “B” Dimension and chalk
another line. Repeat this procedure across the bin until reaching the wall in both directions.
When completed, there should be a set of parallel lines (perpendicular to the floor planks) with
“B” Dimension distance between each line. See Figure 2B.
Chalked lines referred to Step 2

2. Recommended Method for Full Floor Installation
IMPORTANT: Fi rst piece of flooring must start at
the proper distance from centerline of bin. Refer to
floor layout on Page 13. First piece may need to be
trimmed for length to fit at the proper location.

4. Install flooring starting at the bin wall on the opposite side of the unload auger. Floor planks should
be placed perpendicular to the unload auger with the outside edge the correct distance from the
center of the bin.

for flashing installation.)
. Attach
5. POSITION THE NEXT ROW OF SUPPORTS ACCORDING TO THE CHALK LINES and support
layout. The straight tab should “snap” under the first (previous) floor pie ce. After the supports in the
row are correctly positioned, install the next floor piece by hooking the open channel edge under
the outside hooks of the floor supports. Push down sharply on the edge of the floor piece until it
snaps into the previous floor piece. (See Figure 2C.) Continue this process for the rest of the floo r
cutting planks for center and intermediate wells as needed. See Figure 5A on Page 12 for center
well support locations.
NOTE: Whenever there is more than Dimension B divided by three inches (B/3") of plank unsupported
beside the bin wall, there should be a support on that plank or a support on each of the
planks adjacent to it such that no more than Dimension B divided by three inches (B/3") is
unsupported. For example: 2.66" bin with 8 rings has a “B” dimension of 22". Take 22"/3" = 7.33"
(Round to 7"). Therefore, there should be no more than 7" of unsupported floor plank.

4. Flashing Installation
Grain Systems Formed Flashing Installation
If a bin sweep auger will be used, overlap flashing so that the sweep with climb up on to the next flashing
section when rotating (usually clockwise). (See Figure 4A.) This will prevent the rotating/slipping outer
wheel of the sweep from catching on the flashing edges. (All GSI power sweeps and carry-in sweeps
manufactured after April 2002 run clockwise.)
After floor is in place, place 1-1/4" bolts through pre-punched holes in sidewall. Bolt heads should be on
outside of bin. See Figure 4B to determine the correct seque nce for placing the nuts and washers. Finger
tighten the nuts until all flashing is installed, then go back and fully tighten. While holding the flashing flat
and pushing in towards the bin wall, fasten the flashing to the floor with two sheet metal screws.

*For Aeration Systems recessed in the concrete, add one (1) ring for proper spacing.
When using FL-3102-3 or FL-3102-6 (3", 6") Grandstands, increase the listed quantities by 33%
(Standard Quantity x 1.33).
Quantities of Grandstands are minimum required for installation - Due to varying conditions and
construction techniques at floor and wall penetrations, additional supports may need to be
ordered.
How to read the chart: For example, a 12' diameter bin with 7 rings would have spacing of 54/27
(the top numbers). Meaning A=54" and B=27". The number of supports needed would be 62,
(the bottom number).
(* Based upon 13.5" or taller floor heights)
All floor styles OK for
bin sizes in upper

*For Aeration Systems recessed in the concrete, add one (1) ring for proper spacing.
When using FL-3102-3 or FL-3102-6 (3", 6") Grandstands, increase the listed quantities by 33%
(Standard Quantity x 1.33).
Quantities of Grandstands are minimum required for installation - Due to varying conditions
and construction techniques at floor and wall penetrations, additional supports may need
to be ordered.
How to read the chart: For example, a 12' diameter bin with 5 rings would have spacing of 54/27
(the top numbers). Meaning A=54" and B=27". The number of supports needed would be 62,
(the bottom number).

10. Flashing Support Stiffeners
Stiffener Flashing Support Instructions for Internal
Universal Stiffeners
1. Install the floor and support system, cutting the floor to go around the internal stiffeners as required.
2. Break the stiffener flashing support (SS-6984) into its three (3) components.
3. Lay the flashing supports on top of the flooring and weld the flashing supports to the stiffener as
close as possible. Fasten the flashing to the wall, flashing support, and floor. Seal all spaces by
welding or caulking.
4. Paint all welds with good quality zinc rich paint.
5. Stiffener flashing supports (SS-6984) must be ordered separately from the standard floor
and flashing.

11. Air Flow Support Instructions
Installation of Air Flow Supports
1. Determine the spacing and quantity of air flow supports required from the chart on Page 28.
Make sure that the correct supports have been ordered for use with the proper depth of plank
(either 1-1/8" or 1-3/8" deep).
2. Mark center of bin.
3. Install discharge auger.
4. Mark spacing lines parallel to discharge auger.
5. Start on the side of the bin opposite from the discharge auger and place the first two rows of
supports on the spacing lines. Note that air flow supports are installed at an angle in an overlapping
pattern so the ends will overlap. See floor layouts in Figure 11B on Page 29.
6. Install the channel lock flooring on the first two rows of supports and secure in place with bin
wall flashing.
7. Finish placing supports on the spacing lines and installing floor planks.
a. Single supports are used next to the bin wall and at the ends of split floor planks in order to
maintain the floor manufacturer’s recommended minimum distance from the end of a plank to
a support.
b. Double supports are used at the sump and along the sides of the discharge auger for spacing
of 16" or less and for recirculating bin equipment.
c. Full supports may have to be overlapped or angled to provide support at walls and to maintain
spacing and flashing requirements.

Notes:
1. Use a maximum spacing of 16" for perforated corrugated flooring.
2. The number of supports listed is based on the maximum peaked capacity of each bin.
3. Use extra single supports for split floors.
4. Extra supports are required for grain recirculating equipment. Use the manufacturer’s
recommendation for the number and spacing of extra supports. NOTE: For grain flows, air flow
supports are doubled in a 14' diameter in the center of the floor.
5. Contact a representative for air flow supports required for larger bins and deeper grain depths.
6. *Increase the number of supports by 5% when used with 6-3/4" wide mfs floor planks.
