relative strength of alum vs steel rigid conduit?
I sent a note to a manufacturer but no response, and I haven't been able to find this info online, so I'm hoping maybe someone knows or can point me to some hard data.
I am planning to build a greenhouse structure with rigid pipe, and my local store only carries the steel pipe. I see online that there is a cheaper and lighter aluminum rigid pipe, but no data on how rigid it is compared to steel at the upper end or regular alum conduit on the weak end. Can anyone give me a comparison? Before ordering a bunch of this pipe online I need a comfort level that a hard wind won't bend the structure.
