 I have been after a mast for my turbine for ages and they have them there for a reasonable price.

scaffold tubes - thats what i use for antenna masts, ideal for wind turbines. Go to an amateur radio rally to get all the fixings and guy wire/cable stay parts (a mast taller than about 20ft will need stays)

Been trying to get a scaffold pole for ages - no joy.  Just thought I'd get it all in one, and especially one that can take the stress and strain without collapsing! Been given lots of bits of poles but many wrong diameter and far too short - frustrating!

they are a bit tricky to get hold of. I have a duralamin tube i use as one mast that cam from a jig used for lifting boats, had to go to nottingham for it.

the same people who sell the mast fixings will sell the tubes as well.

i want the riggers at work to let me have some of the mast tubes we have piled up, there 20ft long, 18inch wide, and come with climbing ladders!, they bolt together to make masts up to a few hundred foot
