When I was traveling we used to use a lot of uni strut and used to cut it with a metal cutting chopsaw, that was a long time ago, is there anything on the market that has been brought out recently, or better still, what method do you guys use, as I say it's been a while and things have moved on. The reason I ask is I have a mate who has asked me the very same question, and would like to help, so grateful for any ideas.
