A roll-formed door beam is provided for a vehicle which has an elongated shaped including a hat shaped portion and one to two looping portions. The hat shaped portion includes an upper flat surface for attachment and downwardly extending sides. The looping portions includes a bottom flat surface for attachment and looping sides which loopingly extend backwardly toward the base of the hat shaped portion. The looping sides cooperate with the side of the hat portion to stabilize the beam during flexure thus increasing the strength to thickness ratio of the beam.
