Stainless steel is a good conductor, and therefore would work well as a 
Faraday cage.  The cage represents an "equipotential surface" and if it 
encloses completely a volume, no electric field from outside will induce a 
field inside.

The application you describe, though, seems to be more addressable through 
engineering and electric codes rather than the pure theory regarding 
electric field lines.  Electric codes do implicitly include such 
theoretical considerations, but are inclusive of many other factors.  I am 
sure, for example, the stainless steel panel you speak of will be 
electrically grounded.  This way any faulting to the panel will cause 
protective devices to disconnect power rather than have the panel 
electrically "hot" causing a hazard.
