3.2.6.3 Tube dimension
For all constructions the minimum dimension is 38 x 2.5 mm (1,5”x0,095”) or 40 x 2.0mm (1,6”x0,083”). Only constructions made from steel tube are allowed.
It´s strongly recommended in case of replacing the B-bar/main-bar, a major repair of the cage or at new construction, to use cold drawn seamless unalloyed carbon steel tubes with a minimum tensile strength of 350 N/mm. Recommended tube size are 45x2,5mm (1,75”x0,095”) or 50x2,0mm (2,0”x0,083”) for the B-bar. Also recommended for A-bar/front-bar, lateral rollbar, half-lateral rollbar and transversal member.

Eli vaatimus on teräsputki ja vahvasti suositellaan saumatonta.
"Unalloyed carbon steel" sulkee cromon pois, mutta sekin on vain suositus?
