I have looked at them. Here they only come in 10ft sections. Longer may
be available but at a price. The ones that I have looked at seem to have a
thin wall, not very strong. I donot know what alloy Al.
I have been told that the best is the long lengths of exhaust pipe, galvo
inside and outside and strong. Different sizes swedged could make a good
vertical but how I?
Another that I was looking at was electrical piping, the stuff that is used
for the stack on the roof. It is also available in differenct sizes but is
expensive. For my re-service the pipe was CA$60 for 10ft. plus taxes.
