rolling erw or

[I/Mx]

I have to roll some lancet arches for a headboard at approx a 750mm radius.
Would it be better to use 1.5mm erw or standard 2mm box. the size is 20x20 box
I have a small electric roller

You need the correct dies,or do as I do,roll as is ,then accept some minor crushing with 2mm thick box.

Thanks Nick, so it would be better to use the 2mm over the erw ?
