AUTOMOTIVE VEHICLE DOOR BAR OR THE LIKE ABSTRACT OF THE DISCLOSURE An improved strengthening or reinforcing member is provided, particularly an automotive vehicle door bar or beam. The bar comprises an air cooled, hot rolled section of high strength alloy steel having a minimum tensile strength of about 150,000 lb/in2 and a total elongation of at least about 7.5%. In a preferred embodiment the steel comprises about 0.16 to 0.21% carbon, about 1.8 to 2.1% manganese; about 1.2 to 1.4% chromium; about 0.7 to 0.9% silicon; and the balance essentially iron. A clip element may be mounted on the bar to retard or prevent spreading of the flange por- tions of the section during bending. By securing or fixing the clip element to the section, a substantial improvement in load carrying capability is obtained.
