ABSTRACT:
A composite structural frame component which has a high quality appearance and substantial structural rigidity. The component comprises an elongated substantially flat member having a plurality of V-shaped grooves extending through the thickness of such member and tapered marginal edges, such grooves and tapered edges being mutually parallel and parallel to the longitudinal axis of such member. A flexible member, for example having a thickness substantially less than the thickness of the flat member, is secured to the surface of the flat member at which the apexes of the grooves are directed. The flexible member has a surface facing away from the flat member which is of a high quality appearance. Therefore, when the flat member is folded along the grooves to form an elongated structure of rectangular cross-section with a hollow interior, such structure is encased by flexible member. The resulting composite structure thus has a high quality appearance with substantial structural rigidity.
