Radar arch - what tube wall thickness have you got?

[FullCircle]

I am looking at a 38mm diameter 316 polished tube for my Radar arch on the back of Full Circle.

Available isn both 1.5 and 2.0 wall sections easily, and sure I don't need 3.0mm.

I will be using gussets and smaller tube counter/cross bracing.

Anyone know what they have got?
