ooops yes ...1000cm !!Do you mean 1000cm? if so steel poles are best as alloys will buckle in high winds.

I am a very big Isabella fan so my only recommendation is an Isabella Minor, V easy to erect, top quality and althought the bumf says spring to fall we have used our right through the winter with no probs.
Look on Ebay and you can pick up a mint used one for a fraction of the new price.
Happy hunting
