Cattle/horse fencing with it's 6-inch spacing is great for supporting tomatoes and squash as well as cucumber and beans. My local lumber yard sold it in 330-ft rolls (too much!) or short panels about 5ft x 10 ft which I could barely bend over and fit into our hatchback. I didn't think of your neat arbor idea, so mine are just supported by posts at each end. They have been supporting my vine crops for the last 5 years...rusty now, but still going strong.
