Abstract
A standing seam panel for assembly into surface covering is constructed to have a central panel section with a female profile along one lateral edge and a male profile along the other lateral edge so that adjacent panels may snap-fit together by engaging the matable profiles. The female profile is formed as an inverted U-shaped channel by an inner side web and an outer side web interconnected by a top wall. The male profile is formed by a first end wall, an inwardly projecting intermediate wall opposed to an edge portion of the central panel section adn an inset wall extending upwardly from the intermediate wall. The edge portion of the central panel section thus form an inwardly-facing channel, and the female profile includes a detent structure that engages the inwardly facing channel when a male profile is mated with a female profile. A fan-fold fabrication method for forming the profiles as a continuous process of flat sheet stock is described.
