The panels would indeed be heavy. Steel angle iron 1-1/2" X 3/16" (smallest and lightest I’d try to go with a 5’ X 10’ panel) would weigh about 54 lbs. 16 gauge X 1" steel wire adds another 37 lbs. That’s without any braces in the panels. Those are pretty big panels to go with just a picture frame border and no internal bracing. Probably work, but they are going to be flexi.
If you wanted a protective enclosure, is there a reason you can’t build a permanent one? Perhaps some HOA restriction? My daughter had squirrels eating her tomatoes and built an enclosure which doesn’t look too bad. The top is covered and she built a little door to enter the enclosure.
The key to making a fence look good is to make sure it’s very straight (not weavey), no saggy parts, and no parts leaning (which can take some thought when building an enclosure). If a fence is done right, it can actually add to the appearance.
Here’s a topic @tonyOmahaz5 started when he finished his fence.
I know that’s not the type of fence you are looking at, but mention it as a point that fencing of any type can look good, if done right.
Here’s a pic of my fence. It’s a rural deer fence, but by rural standards, it looks pretty good.
