A vehicle beam component includes an elongated beam having a first wall, a second wall, and a third wall interconnecting the first and second walls to define a channel along a length of the elongated beam. The vehicle beam component also includes an array of stiffening members secured in the channel and disposed along the elongated beam in a spaced arrangement that is configured to stiffen the elongated beam from a laterally directed impact at a majority section of the length. Each stiffening member of the array of stiffening members extends between and is secured to the first and second walls of the elongated beam. Each stiffening member also includes a wall portion that is disposed orthogonal to the third wall of the elongated beam and transverse to the length of the beam, such that the wall portion is configured to axially absorb the laterally directed impact.
