Mine are close to 20 years old and they are still brown. They don't seem to rust away. You can buy galvanized fencing of different heights. The CRW is sturdier and it has holes large enough to get your hand through even with a big tomato in it. CRW can be useful for all kinds of things. I use it for compost bins and to protect plants in the winter. My bananas com through freezes down to 15 degrees. I put CRW around them in a circle and fill it with pine straw and cover it with a tarp. If you don't keep it dry the banana plant will rot. Ask me how I know that. In the spring I just use the pine straw in my beds or around my tomato plants. Just cut 3.1414 time as long as you want the diameter if you remember your geometry. If I didn't have CRW Iwould have to invent it and brown doesn't bother me.
