A high strength reinforcing beam structure is provided. The beam structure includes an elongated member, with at least a portion of a length of the member having a cross section which defines a first, a second, a third, and a fourth curved segment. Each of the curved segments has a shape that can be defined by a hyperbolic cosine function. In addition to the high strength reinforcing beam structure, a process for making such a structure is provided. The process includes feeding an elongated member at least partially into a roll forming machine, the machine forming at least a first portion of a length of the elongated member such that the cross section has a first, a second, a third, and a fourth curved segment, each of the curved segments defined by a hyperbolic cosine function.
