2.66'' Corrugation Commercial Stiffeners Splice Details
When installing bottom stiffeners, you may find that in some cases the stiffener with base plate attached
will not rest on the foundation (due to unlevel foundation, etc.). Shim plates have been furnished and
should be used to fill opening between base plate and concrete.
IMPORTANT: If shim plates are not used where required, the downward pressure of the stiffeners will not
be transferred directly to the foundation and bin failure could result.
