ABSTRACT:
A metal panel, particularly though not exclusively for use as an outer panel of a refrigerator door or hinged freezer lid, has a peripheral lip forming an inwardly facing channel. The channel is formed by two folds, the outer fold being formed by roll-forming operations and the inner by a folding machine or the like. This (a) permits the panel forming machine to be more readily adjustable for different sizes of panels, (b) permits the lip to be made up of a number of folds (which strengthens the panel and permits thinner metal to be used), (c) avoids the need for corner welding, (d) permits a lip profile into which a gasket can be snap-fitted and (e) permits precoated metal sheet to be used.
