1. Determining the layout of the bin stairs. (See Figure 2A.)
Figure 2A
2. Locate the platform directly under the roof ladder and manway hole. The location of the platform
and manhole must be pre-determined so that the stairs will not interfere with auger, doors, fans, etc.
To determine the stair locations, count the number of bolt spaces around the bin according to the
Chart below . This will give the ending location of the stairs. Each step is 8" tall and wraps around the
bin one bolt spacing or 9-3/8". NOTE: One bolt spacing is the distance between the bolts on the
horizontal seams, which is equal to 9-3/8". On a 2.66" (32" sheet) corrugated bin, the first ring will
contain the platform at 16" below the eave and two (2) steps. There are four (4) steps for each ring
thereafter and the four (4) stairs wrap around the bin four (4) bolt spaces or 37-1/2" per ring. Use the
Chart below to determine how many bolt spaces you must allow for the steps during installation.
