I am doing freelance work ( consulting) and the place I am at has 4 large bucket elevator, scales etc. Equipment is aged. Equipment is now full of holes either from them making new holes and where some nuts and bolts used to be and they figured they don't need them. Is there any suggestions on how I can close these holes ? ? It's mainly stainless steel and plexi . Maybe rivets? Maybe replace the nuts and bolts ( in some areas the reason they bore new holes was loss of threading in one area) Please assist?.

Personally, if it is just stainless steel I 'd have them dab some weld in the holes and grind them flush. If excessively large holes or a number of holes in close proximity, weld a plate over the top. A good weld will have decent surface easy to keep clean. 

For the Plexi, if it's sheet plexi, it'd only cost a few dollars to replace.

This is what I would do.

 

For the stainless steel, have a certified/professional welder or metal fabricator build up metal in the holes while making sure that they have a completed area that is smooth and has no places for food to collect.  I say to use a certified welder because stainless steel comes in several alloys, and the rod/settings used will be different for each.  Plus, if they melt holes in the metal, you should be able to hold them responsible.  Welding stainless is not cheap and is tricky, but if not done correctly, it will not be a sanitary surface.

 

For the Plexiglas, it's harder.  I don't think you can "fill" holes in that, and it's hard to re-create that smooth surface once it's been cut.  It may be cheaper to just replace the entire piece rather than try to get someone to fill holes correctly.  I'd talk to a local company that fabricates Plexiglas.
