Abstract

A shutter sheet consisting of a hollow profile tube made by longitudinal folding of a metal strip, the lower side of the sheet having a central longitudinal groove bounded by two surfaces that transition with the side walls being provided on the upper side of the sheet a central longitudinal rib, whose thickness is less than the width of the lower longitudinal groove and which, at its upper edge, is provided with two flanges extending to the side and which, when the rib is inserted into the lower longitudinal groove of another equal sheet, they fit behind their limiting surfaces, characterized in that the two flanges are formed by the two longitudinal edges, and the rib by the juxtaposition of two marginal strips of the metal tape, and because. The parts of the lower side, which limit the lower longitudinal groove on both sides, are joined together by the central part of the tape bent approximately in an inverted u-shape, so that a cavity is formed, the bottom of which represents at the same time a reinforcement of the hollow profile, which prevents the side walls from being pressed against one another.
