heya all, another question. this time about roll cages.

i have a alloy cage in betsy, but im thinking of building a steal one for my new project.

what would be the best stuff to use? thickness, size, etc.... has to be able to get a engineers certificate after construction.

any help much appreciated.

I'm not sure about which stuff to use, but won't steel just add excessive weight?

Just to add to above, CDW (welded) or CDS(seemless) is OK.

CAMS have it all wrong here. Dick Johnson used good old Palmer Tube Mills (now Smorgan steel tube) pipe in his Sierras and these cares were shipped to Oz in half cuts, easier to ship.
The CDW and CDS is not made in Australia and has to be imported, expensive.

Good enough for Dick the Ozzie made 450 grade should be allowed but CAMS are knobs!!!

If its about protection why don't CAMS make the older log booked cars with alloy roll cages put the steel cagesin?
