thats not correct actually. there is a requirement that states what ever is used for a seatbelt mounting point needs to be strong enough/fit for purpose. in our case the cross bar is part of the upper seatbelt mount assembly as is the roll bar and the way it attaches to the chassis. the tester will be looking for something that is strong enough to do the job.

i would say 48mm 4mm thick will be plenty strong enough but make sure you take some pictures of the material prior to using it as it may be brought in to question during the test.
