Roll Bar Back Stay Material

[MikeB]

I have the main roll hover hoop from Ash's bulk buy.
What material, dia and wall thickness have people used for the back stays and the cross bar (that need to be wide enough to drill and weld the seat belt bosses in).
Any ideas on price and supplier?

Mike use the same size and you will get that from AH Allens in Northampton

cross bar would need to be about 30 mm 2.5 wall and back stays about 30mm with about 1.5-2mm wall
think its in the book
as for supply could try some local engineering/fabricators
