Rollover safety ring for vehicles

A rollover safety ring for a vehicle that defines a longitudinal axis (L), a vertical axis (V) and a transversal axis (T), the axis (V, T) being orthogonal to each other, and comprises a plurality of structural arches spaced from each other in the longitudinal axis (L). The plurality of structural arches defines an inner safety space for passengers, each structural ach being formed by a plurality of tubular steel profile sections coupled to each other. The steel of the tubular steel profile sections comprise an amount of carbon between 0.15% and 0.35% in weight, an amount of boron less than 0.005% in weight and a carbon equivalent content, CE, that is lower than 0.78, and wherein a thickness of the tubular steel profile sections is between 1 mm and 5 mm and a tensile strength of the steel is higher than 1,000 MPa.
