Abstract: An impact beam having a polymer matrix and a metal reinforcing structure, the metal reinforcing structure including metal cords that can be made from metal elements having a diameter of 100 ?m or more. The polymer matrix can include a thermoplastic material and/or a fiber material, and the metal can be steel, and the metal cords can be parallel to each other. The polymer matrix can include two or more layers that can be made from the same or different material, one of which can be positioned around the surface of the metal cords and can have a mechanical bond with the cord. The invention also includes a method of making the impact beam.

Abstract: Described herein is a door assembly that includes a flexible panel of flexible plate material which is guided in channels between a closed position to an opened position; the flexible panel assuming a substantially horizontal position in the open position and thereby increases the height clearance in the door opening.

Abstract: A door assembly for a doorway opening, such as a garage opening, comprises a door with a flexible door panel. The flexible door panel is guided around rotatable guide wheels between a closed position and an open position. When in the open position, the flexible door panel is substantially horizontal to maximize the height clearance of the doorway opening.

Abstract: A frame having a U-shaped cross-section is clamped at a wall rim bounding an opening in a wall by means of a clamping jaws. The clamping jaws are formed by a steel sheet bent over in its longitudinal direction and are profiled substantially throughout their lengths, so that with a small thickness of material the clamping jaws mainly derive their rigidity from their profile.
