1. Determining the layout of the bin stairs. (See Figure 2A.)

Figure 2A Bin Bolt Spacing

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 on Page 8. 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 4.00" (44" sheet) corrugated bin, the first ring

will have the platform at 16" below the eave and a four (4) step section directly below the platform.

3.5 of these first four (4) steps will be within the first ring. There are 5.5 steps for each ring there after

and the (5.5) stairs wrap around the bin (5.5) bolt spaces or 51.5625" per ring. The stairs will be

assembled in four (4) step sections. Use the chart on Page 8 to determine how many bolt spaces

you must allow for the steps during installation.
