It's like Lego for adults; lengths of aluminium section with connecting pieces used for constructing test beds and machinery platforms - have seen it being used by IKEA for the machines they use to show their chairs being tested?
Ta!

Engineering question; what's the stuff that test labs and IKEA use called..?

This http://www.8020.net/ ? Used for frame jigs too.

You mean Rose and Krieger or Bosh Rexroth. It's good stuff but not cheap, you can get small amounts from RS uk.

Brilliant - thanks to you both!
Not on the same scale as Wozza's photo... just something I may try making!

There are several companies that make is just google extruded aluminium , extruded aluminium frames take a look around e.t.c

TheBrick; found a few more since - just wasn't sure what I was looking for, or what to Google. Valuframe looks promising, too.
(Kinda toying with making a bike trailer, a 'project' for over the summer...)

Yeah I know I wasn't trying to be a smart arse. I was looking into it last year and had trouble finding the appropriate google phrase too.

I ordered a pile of it from http://www.aluminium-profile.co.uk/ last month for start gates.
All came nicely cut to size, although I do have 6x300mm 40x40 bits left as I allowed abit too much for length and had to chop them, which you can have if they're any use to you.Posted 11 months ago # -
The Rose & Krieger cast aluminium clamps from wozzas link with some aluminium tube might be better for a trailer. There are some cheaper fittings available too (heavier, less precise, generally used for handrails)

Some trailer that's going to turn out to be!
I was hoping you were going to make your own mechanical bum.

Just a pipe dream at the moment... would model it using either Pro/E or Inventor and get an idea of weight - and cost.
MC; ta! Did you model/design first or just 'build'..?

Basic sketch/weight calcs were done on abit paper (loads of stuff on the web for calculating load/deflection for all the profiles) to make sure I got a strong enough profile.
Was far easier than making them from steel, plus they end up lighter and stiffer, although a good bit more expensive!
I missed the comment about it being for a trailer. One thing you'll have to look into is the grade of alloy and galvanic corrosion, as I've seen underun bars falling of lorries within a couple years, because the alloys corroded to nothing around the bolts/nuts.

Good point about the corrosion...

I bet you could get a steel frame welded & powdered for about the same cost, with no fasteners to worry about. We use the stuff, but its pricey & I'd be concerned about it working loose over time on the road. It's good for quickly lashing up test rigs & benches though.

And another good point..!
