Improved arrangement in profiles that behave laminar bodies, characterized in that according to the same in the cross section of the profile and at each end of it is born on one of its faces a cantilevered skirt, while on the other side and in the opposite direction is born a broken skirt that at its end has a flange of diminishing section forming between this flange and the broken skirt a cavity of smaller width, while between said lateral flange and the body of the profile itself is constituted a second cavity of greater section, existing between both skirts an antirechupe groove; all this in such a way that in the same profile, metal sheets of less thickness can be lodged indistinctly in the first cavity, or else thicker wooden sheets in the second cavity with a greater section, thereby achieving total versatility.
