6.36. Typical Non-Structural Roof Installation
The following is a step-by-step procedure for assembling a non-structural roof system.
Prepare the Peak Ring
1. Install the supplied bulb gasket around the top of the peak ring. Trim to fit.
2. Install the foam closure gasket around the center section of the peak ring. Trim to fit.
Refer to

Step #3: Add the supplied bulb gasket
around the top of the peak ring and
foam-closure-gasket around the
center section as shown (Detail 1).
Step #4: A tier of wall sheets (or possibly
to support the roof. Start assembling
Usage” section in this manual for
When one tier is complete attach the
wall sheets. Do not allow a joint between two adjacent top-ring-angles to
be positioned directly over the Grain-gauge
cutout in one of the top wall sheets.
Ensure that the joint between top-ring
-angle sections is at least 2 or 3 wall
sheet holes away from the Grain-gauge
cutout. Follow guidelines concerning
tank roundness tolerances as laid out
on the Bin Roundness page in this
manual.
Step #5: Suspend the peak-ring assembly to the top of the center post. Refer to the "bin-
roundness-table" for correct heights and peak-ring sizes (Detail 2).
Step #6: Begin laying out roof-panels by attaching
the narrow end to the peak-ring and the wide
end to the top of the top-ring-angle. It is
recommended that you first attach four roof-
panels at the quarter points of the bin; this will
stabilize and support the peak-ring for the rest of
the install (Detail 3). Ensure that the gap
between the roof-panel and the peak-ring is
sealed by foam closure. (Detail 1). Note that the
center hole in the roof panels aligns with round
holes in the top ring angle.

TIP
:
The narrow end of the roof panels gets pushed into the foam closure. Once this occurs there is
little room for adjustment at the top end as the roof panel is embedded in the foam. Sometimes
the roof panels get “flattened” slightly from bundling, shipping and handling. It is relatively easy to
push the ribs together slightly but this should occur before the panel is seated in the foam.
Monitor the alignment of mating roof panels with the underlying holes in the peak ring and make
adjustments, if necessary, before anchoring the roof panel into the foam.
IMPORTANT: Avoid shortages.
Consult “Hardware Usage”
table for proper hardware
usage for all bin connections.

Assemble the Top Ring Angle
1. Attach the top ring angle to the inside top of the wall sheets.
a. Do not align the top ring angle joints with wall sheet joints.
b. Make sure that top ring angle joints are at least two or three wall sheet holes away from the Grain
Gauge cutout.
c. If building a stiffened bin, do not install the top angle bolt that lines up with the stiffener holes at this
time. It needs to be installed with the stiffeners.
Install the Peak Ring
1. Determine the correct peak ring height (H) for the bin size from
.
2. Attach the peak ring assembly to the top of the center post at the correct height for the bin being
assembled.
