Abstract
A laterally bent, impact resistant, reflective trim strip adapted to be longitudinally curved without subsequent wrinkling of the reflective material is formed to include an extrusion comprising a transparent plastic sheath encapsulating a composite metallized strip. This metallized strip has a film of metal sandwiched between and bonded to a layer of high strength and high temperature resistant transparent plastic, such as polyethylene terephthalate, and a layer of opaque plastic, so that the metal film is visible through the front face of the extrusion. The lateral shape of the extrusion provides a central portion lying in one plane and an edge portion lying in another plane so that when the extrusion is longitudinally curved, either the central portion or the edge portion will be placed in compression. The extrusion is modified herein by an elongated compression-resistant element, such as a metal stiffener, which is secured to either the rear face of the central portion or the edge portion, depending on how the extrusion will be curved, to minimize the compressive forces which are imposed upon any portion of the extrusion when the same is curved.
