Yes, I agree it is getting confusing. There is a “trellis” structural frame that is made of hollow steel structural members.
There is a “mesh canopy” that stretches over this trellis type frame. We have been trying to get data on construction material and percent opening. I don’t have the drawing open at this time. The structure butts up against the main building and extends out about 30’ from the building in the West, north and east. It wraps around a section of the building.
