Thats is a good idea but I find they rust out on the joins where the screws go in. We have already replaced one, OH made a wooden one, and now the other has gone. Its very exposed up here and very damp and windy, long 2 x 2 s banged well into the ground seems to work, its the tops that go.
The obelisks have lasted just 3 years, although it was only the plants holding them up last year!
