A vehicle body frame structure having two closed cross sections is disclosed. Each of the closed cross sections (35, 36) is isolated in a longitudinal direction of the vehicle body frame (34) by barriers (37, 38) and structural foam fillers (41, 42). The barriers are spot welded (43, 43) to the front and back of a reinforcement panel (33) of the vehicle body frame.
