"Here are some photos of my patio trellis build. It uses a 16ft x 50in cattle feedlot panel from Tractor Supply. Most of the weight is put on the feet on the ground and the mount points provide lateral stability.

The mount points to the pool enclosure need to be extra strong because of hurricanes (Milton hit nearby and this was unaffected). They are bolted into aluminum rivet nuts with stainless steel bolts. I used aluminum rivet nuts and stainless bolts to reduce galvanic corrosion.

The cattle panel connections are held up by resting the wire on top of countersunk sheet metal screws on the back. Tractor supply sells a tool for twisting the wire that makes getting this tight easy." - Matthew
