Abstract

A method of making an access cover of tray-like form for receiving an infill, comprises the steps of starting with a flat metal sheet, forming notches 9 in the corners of the flat metal sheet so that the sides 12, 13, 14 and 15 of the access cover can be pressed out of the plane of the plate to lie adjacent to one another, pressing the sides of the cover out of the plane of the plate and, in the same pressing operation, pressing stiffening ribs 17 in the base of the cover.
