SB , why not build a good gazebo and put real screens on it . I just ordered a 4'x100' roll of 304 ss screen 18or 20 mesh . This is smaller holes that most fiberglass screening that you get at the hardware store. It runs about $900.00 . You can get 409 cheaper or mild steel a lot cheeper . I would not use aluminum or fiberglass anymore ,that stuff does not last. I ordered from Mcnichols company.
