PVC is CHEAP! However, it has no real structural strength and, in cold weather, often gets brittle and fractures. PVC is made for carrying things like water and is definitely not made to be able to withstand any forces other than moderate pressure (i.e. water pressure).
People do make things from PVC on which they do put structural forces. However, doing so is at their own risk and quite often the structure does not survive.
