Are the poles broken or did you not use the tethers to secure the poles? Unless it was a bad storm with heavy rain & wind, the awning shouldn't have come down from some rain and wind, if it was setup properly. Since you haven't posted a source or brand of awning, it's probably best to check with where you purchased it. If you got it online, maybe a local dealer that sells awnings can help you with similar poles.
Thanks for the reply. It just a ARB knockoff awning from Ebay. The pole bent under the weight of the rain collecting on the awning. The poles look like generic aluminum poles with a twist lock...I just have no idea where you can buy something like it
