Overview for a Typical Bin Installation
These are the typical steps one would perform when constructing a grain bin. Procedures may vary
depending different site requirements.
Pre-Assembly Activities
• Sorting and grouping parts
• Assemble A-frames
• Assemble center collar
• Assemble cap plate
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 gage 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 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 eave angles to the sidewall sheets (Note how these are aligned.)
• Install the tension member to the eave brackets
• Lift pre-assembled A-frames, installing them in “opposite pairs” (across from one another) to balance
out the load as you install
• Install lower roof panels
• Install upper roof panels
• Cut roof exhauster holes evenly spaced in upper panels
• Install upper flashing
• Install roof exhauster
• Install flat top
