Hello Dave:
 
Are you really sure you want to use queen excluders?
 
I use two deep bodies for my bees and seldom have any problem with the
queen laying in my honey supers.  I also, but not always, reverse my hive
bodies to keep any space in frames in the top body.
 
I have a few excluders and on occassion may put one on but generally they
are stacked in my garage.  I do plan to use some of them this year to try
Nick Wallingford's (New Zealand) technique for requeening or dividing a
colony without finding the queen.
 
If you decide you must use excluders, I would suggest the welded wire
with wooden frames.  Be sure to paint the edge of the frames.
 
Good luck with your exclusionary process.
