Need to build a projection screen for our upcoming production. Our rigging points are DS of proscenium and are 16' apart (left over from the original tour of Phantom). The overall size of the screen is 18' wide and 11'4" tall. The perimeter has some added, not structural, detail that creates a decorated frame. It must break down into pieces no bigger than 8'x16'. It will be hung at a trim around 30', static during production. One time use, not saving. One day load-in with IATSE stagehands.
Original idea (see attachment): build four steel flat frames out of 1.5" square box tube. Bolt them together along the edges. Stretch a fabric over the whole frame and staple to wood on back/sides. Rated eye-bolt (in red, cable in blue) at the bottom. Screw on decorated frame pieces, then fly out.
Do I need more structure in the frames for the span? Will 1.5" square tube work, or should I bump it up to something bigger? Is there a better way?
