Abstract
A method of making a beam-box crash management system comprises forming a first shell (100a) from a first sheet metal blank by a hot forming process. The first shell has a high tensile strength beam portion (102a) and integrally formed there-with a first low yield strength crash box portion (104a) proximate a first end of the beam portion and second low yield strength crash box portion proximate a second end of the beam portion. The first shell also has an open face extending continuously along the beam portion and each of the first and second crash box portions (104a, 106a). A closing element (100b) is formed from a second sheet metal blank, and is fixedly secured adjacent to the open face of the first shell.
