I use these for an archway over some steps with vines growing on it. They work really well, are sturdy and can really take the wind. Gonna use them this year for my tomatoes in the garden and horizontally for my raspberries, cucumbers, and peas.
Cattle Panel Trellis - supported by either 4 rural log fenceposts (what are they called?) - or 4 4x4s....SOOOOO much less visually obstructive, way cheaper, actually wide enough for the rider mower, and will be all covered over in a few years leaving just greenery!
