A door, for example for use in industrial and commercial premises, designed to be pushed open by pedestrians or vehicles such as forklift trucks, comprises at least one member (2, 3) integrally formed with mounting means (10), by which it is mounted in an opening for use, and coupling means (14, 15) at which at least one panel (4) is retained to the frame member. The or each frame member is preferably a pultrusion or extrusion of fibre reinforced plastics material. Preferably it is hollow and the mounting means and coupling means extend for its length, the mounting means being, for example, of circular or rectangular cross section and the coupling means being opposed flanges (14, 15) between which an edge of the or each panel is secured. The panel or panels may be rigid, for example of glass or a plastics material. Bearing assemblies (6, 7) are applied to the or each frame member for pivotally mounting it, and so the door, in an opening and spring loaded return pivot means (44) normally urge the frame member, and hence the door, to a closed position. |
