What are the gutter poles made of and will they last?

The gutter cleaning poles are made from aerospace-grade aluminum, the same material that is used to build commercial passenger plans.  The material is very durable and lightweight and only weighs 1 lb 6oz.   They will not crack or bend and will take years of use.  The poles are secured together with quick-release clamps made of stainless steel and alloy, so as not to rust.
