At work, we ground all fabric, then using the same cable, bond the posts and top and bottom rails, so they make electrical fittings for this.

   The phrase Faraday Cage has come to have multiple meanings.
   As an arc/spark catcher, I'd think what's described would work.
   Things to be wary/aware of, in my experience:
    top and sides are mentioned, needs a BOTTOM.
    Grounding is semi nonrelavant, so long as continuity
    between the wires is maintained.
    Which raises another thought:
     Usual 'chain link fence' does not guarantee electrical
     continuity.  Effective faraday cage requires
     continuity.
    Some level of continuity is required at 'edge':
     wall corners, walls to roof, walls to
     floor/bottom.

For effective emi/rfi control the electrical continuity
aspects become more critical, and careful, designed handling
of ALL wires passing thru the wall.  (details on request...)
