I second that. Ours was a large one made of strong metal poles but the whole thing was a right off after snow, as all the poles bent.
We made a new one last year with poles from old gazebos. It was about 8ft wide and 50ft long and covered a row of blackcurrants intermixed with gooseberries and blueberries in pots. It was very successful. We took the netting off when the fruit had finished and the structure has survived so far.
