Interesting. Is that just for straight runs, or do you have a means of engineering bends? ... and if you are talking about 'real' scaffold poles, what about the rough inside surface that flameport mentioned?
Kind Regards, John
As far as I know there is no means of engineering bends on site, but the companies that produce those bars can make curved ones to order. I imagine it requires fairly serious machinery. Usually these days aluminium scaffold pole is used, but older ones were standard galv. steel. I must admit I'm never examined the inside of an old steel one.
