Glad to help, it was Uncle Ben's who found that site a while ago.
Hmm, http://www.metalsupermarkets.com/ sells some piping I think, they're located in Boucherville and Lachine. If they don't have it in stock they can no doubt locate it for you, they're great to deal with (even if that guy on the first page looks like he's gonna take that beam and shove it up your arse)
