... and is it any good for rollcages?
I've heard of CDS but not CHS

Circular hollow section

basically no is the easy answer.

I will vouch for that aswell - as I've been stung by this easy mistake to make

So much so that I have binned the idea of a cage completely - afterall, E36's are strong shells to start with - lots of side impact protection and the like

Its rolled and welded, so nowhere near as good as CDS

A cage can be made from CHS but if your using it as means as a form of protection its not advisable Fraser.

Depends on what its for etc..

thought it was rolled and welded but wasn't sure. It was for the mini (trackday/good weather toy) but i want a decent cage so ill spend a bit more and get a Saftey devices one
company making the CHS ones look to be bunch of crooks anyway after a quick google

same principle of how an exhaust is made?
i couldn't imagine that being very strong..

Andy @ Geronimo then was it ?

He does them in CDS and T45 too for Mini's

Not 100% true. Cold formed CHS is rolled and welded (and relatively cheap).

Hot formed CHS isn't welded, but its almost 5 times the price.

Neither are the best material for roll cages, although both would do the job if made properly.

Yep it was, you know of him then? the mini forums seem to be full of people complaining about poor quality, fit, customer service etc.

Same sort of principle yes, but obviously on a much thicker cylinder wall if you were going to use it for something structural.

Ah, fair enough wasnt aware of the hot formed version.
