Abstract
A sheet metal base panel for use in elevators is disclosed wherein the said base panel is made from sheet metal of low thickness without compromising its structural integrity, by a specialised hemming process. The said base panel is constructed from a single sheet of metal and incorporates the top and bottom header to form a unitary component. The construction is such that the headers can be positioned either way and hence possesses rotational symmetry which enables in easier installation. This is achieved by a special bending of the base panel on all edges of both the top side and bottom side, four times—a first 90° bending () followed by a second 90° bending (), a third 90° bending () and a fourth 180° hemming () of the open edge formed after the third 90° bending ().
