Yes mild steel ...I don't know what Mike used but it should be 25x25x3mm box section ...A length is around 20-22 feet but you will be surprised how much you get through ...I think the original S*mmio frames were about 3 lengths ..
You could get away with 20x20 if you are adding to the existing structure ...if you want some brackets to use as bolt on points ...there are probably some on the existing frame , as Mike used my program at my suppliers ...arch shaped brackets about 50mm wide and some 25mm wide brackets with a hole either end ...I have a selection at the workshop ..happy to post you some ...I use the larger ones as seat belt points too..
