PURPOSE: A door impact beam for a vehicle is provided to maximize strength of the central part of the beam, which is easily deformed by crash, with a reinforcement beam and increase absorption and stiffness of impact energy by placing a part generating deformation by bending as far as from the drive, thereby safety of the driver can be guaranteed. CONSTITUTION: A door impact beam for a vehicle(1) is composed that both ends of a beam(3) are fixed in both sides of a door inner panel by brackets(5). The beam is made up of a circular pipe. A reinforcement beam is inserted in one side of the central part to build up a compression unit(P1,P2,P3) in order to fix the beam. The compression unit compresses three positions of the beam.
