  • Magnetic bird screen
    Patent number: 8511002
    Abstract: A magnetic bird screen for an opening of a steel structure such as a bridge or the like includes a magnetic sheet sized to cover the access opening and at least partially overlap the steel structure at the opening so that the sheet is magnetically secured to the steel structure. The sheet has a plurality of spaced-apart holes sized sufficiently large to permit the passage of air and water therethrough and to be used as finger holes for installation and removal and sized sufficiently small to prevent the passage of pigeons therethrough. The sheet can be folded or rolled upon itself so that the sheet remains secured at one side of the opening or the sheet can be entirely removed when it is desired to have access through the opening.
