I think what you've found is fine to make tomato cages and trellis too. The 6" x 6" mesh size is the right size as well.
Now the question: what is the roll size and how much does it cost ?

Hi Seysonn, the roll is 30m (about 90ish feet), more than enough for me...only require about a dozen cages however i won't have any trouble finding a home for the surplus. Lots of friends/family growing toms just using stakes.

Cost is AUS$100 (about $110 US).

IMO that is very good for cages. Super sturdy and will last a long time. It's what I used. I like the 6" openings because you can stick your hand/arm through, and pull out tomatoes, no problem. The cages require a bit of work at first to make them, but they will last a long time. I made mine at least 5 years ago and they are still going strong. The same size rolls are for sale here perhaps a bit less expensive, but not much. Thats a good price. It'll make 12-15 cages approx 2' in diameter.

I remember coming across a video on youtube the guy was making cages out of that stuff they float in concrete in the concrete section of Home Depot or Lowes. Is that what you got? 10 gauge is some pretty thick stuff. I'd think it would be.

I got 9 gauge and can bend it by hand into hoops for low tunnel. The CRW is more like 6 - at least the stuff I used for my fencing.

its not crw wire, the wire is marketed as heavy duty dog wire as per the link......

i'm 'down under' and on the metric system so i may have got the gauge wrong when converting it to the US way, but the wire is 2.5mm, which is 1/10 of an inch. anyway, its sold in a roll so should be flexible enough.

Here is a link that might be useful: Cage Wire

I think that would be strong and it's clean unlike the other stuff I mentioned. I'd say the opening is fine at 6"x6". Although I've grown tomatoes that big most are much smaller. And you should be able to reach in and trim whatever you need or want to trim.

You found remesh wire! I love that stuff for tomato cages. 20 years old and still indestructible.
