Started the build of the IE version here in Perth, Australia.
Size: 1200mm x 900mm
Pipes: 25mm x 3mm anodised aluminium
Pipe Detail (had a few queries):
I got the pipes from ULLRICH Aluminium here in Perth, Australia.
Cost me $41.65 per 6.5m length, and they cut it to size for me for free.
They seem to have offices in each state of Australia: http://www.ullrich.com.au/contact_Au_Sales.php
The actual product I got is apparently designed for boat rails etc. (hence the "BRIGHT DIP CLEAR" chrome-like anodised finish).
The actual product code is:
UA1248 6463T5 6.5M
EXT TUBE Dia 25x3mm
AN 5-7um BRIGHT DIP CLEAR
There is some flex in the pipes if enough pressure is applied, so I may consider inserting 19mm carbon fibre tubes into some / all of them later.
