You'd be surprised. I know when I priced a project earlier this year, there wasn't that much difference in price for the box section that I needed. It was all the brackets that bumped the price up. I still went for the alloy though, as it was lighter with less flex which suited the application, and the company cut it all to length so all I had to do was bolt it together, which saved me a lot of time.
