I use cattle panel for trellises in my boxes. I use a grinder to cut the panel into pieces. I then use the grinder to smooth the cut metal edges.
Some of the trellises are 1 piece with 8" "tines" and I just stick them vertically into the dirt at the edge of the box. Parallel vertical pieces enclose the box contents. I used single panels for cukes and peas.
I connect 2 pieces using small U-bolts. This makes a collapsible tent shaped trellis.
This type of trellis is easy to move around as I alternate which boxes get which plants. They are also easy to cut to sizes that fit different situations.
I also use cattle panel for espalier apricot, blackberry, and apples. That is sort of a trellis.
