IMPORTANT: BOLTING PATTERN BEGINS IN THE CENTER OF THE SHEET. When starting to
assemble the sidewall rings to one another. Be sure to start in the center of the sheets
and work to the outside edges (horizontal seams). This allows the sidewall sheets to draw
up evenly.

Once you have selected the proper gauge material, begin assembling all sidewall sheets in the following
manner: Standing on the inside of the tank, place the left panel to the inside with the right panel to
the outside.
NOTE: The rope caulking is installed before each sheet is assembled. Wipe sheets clean where caulking
is to be applied. Apply caulking on each side of the holes in the vertical seams and also on each
side of the horizontal row of holes.
Using correct size bin bolt throughout, begin assembling sidewall sheet end to end (overlapping the same
way throughout) until the ring is completed. All body sheet bolts are to be installed with the bolt head and
its neoprene washer to the outside and the nut to the inside. Do not tighten bolts until all sheets are
assembled and form a complete ring. Remember to attach lifting straps at the bottom of the vertical seams
while bolting the sheets together. These straps, coupled to the jacks, will enable you to later elevate the
tank. Now tighten the bolts, in sequence, starting from the center and working to the edge in both
directions. This permits the sidewall sheets to draw-up evenly. Complete one ring and stop. You are now
ready to assemble the roof.
