Abstract: A generally stainless steel construction element, such as baseboard trim, crown molding, or wainscoting, comprises a span of continuous sheet material having a leading top edge folded back upon itself in a fashion to form an integrated leading top edge groove to accept an edge of a first planar material, such as a wall board, within the leading top edge groove. The construction element may further comprise a leading bottom edge folded back upon itself in a fashion to form an integrated leading bottom edge groove to accept an edge of a second planar material, such as flooring, within the leading bottom edge groove. In an embodiment, the construction element, the first planar material, and the second planar material assemble to comprise a continuous surface barrier. The construction element may alternately comprise one of the leading edges to be folded back upon itself in a bull nosed fashion.
