  It doesn’t have to have holes to block radiation. A continuous sheet blocks all frequencies. A mesh is just nice so we can see through the cage or allow air to pass etc.

  From the page you linked: “A Faraday shield may be formed by a continuous covering of conductive material.” “… if the conductor is thick enough and any holes are significantly smaller than the wavelength of the radiation.”
