FIELD: transportation.
SUBSTANCE: method comprises stages at which: first frame is provided being made of the first material and this first frame forms corresponding surface of the first material and this first material is metal; first element is provided being made of the second material; the first element forms corresponding surface being made of the second material and this second material is plastic; then corresponding surface of the first frame is glued to corresponding surface of the first element. Thereby the first frame or the first element or both form channel which partially comprises air duct after gluing of corresponding surfaces. Air duct is formed by interaction of the first frame and the first element. The first frame passes across vehicle from adjacent to one vehicle pillar to adjacent to opposite vehicle pillar. Air duct passes essentially the same distance as the first frame.
EFFECT: integral structure with small weight.
