I know it won't help Yugant and a little thread hijacking....I was at Stokes appliance parts Palmerston road Ringwood (Melbourne, just off Heatherdale road) and went past CMA Metal recyclers (same location).
I spied with my keen eye a larger selection of used round tube stock of various big diameters; thicknesses and lengths...perfect for a pier project! Also saw some rollers from conveyor belt systems which may suit as well.
FWIW...thread hijack off.....
