precast double tees
does anyone know who produced and may have supplied 8 foot wide, 32 inch deep double tees in 1970 for a building in lacrosse, wi.  i have checked with jw peters, spancrete and midstates concrete and they did not produce this size at that time.  
how about iowa precast in iowa falls, ia.?
i would check with both iowa and minnesota precasters.
have you checked with wells concrete?
jike:  thanks, i checked with wells and also hanson, no luck.  do you know the names of others precasters from iowa & minnesota?
how about ipc in des moines?
you might find more by doing a "google" search or asking who else you might call from the suppliers you have contacted.
jike/jae  thanks for the reference to ipc.  i contacted them and they are looking thru their records.  it seems no one that works there now was there in 1970 so they didn't know if they may have produced them, but will check.
