A metal structural panel being suitable, for use in point of display assemblies or other cladding in retail outlets, comprised of a length of metal sheet deformed uniformly and repetitively across the width of the sheet. The panel is manufactured in a machine of two main parts, top and bottom tooling. Firstly the top tooling is moved down onto the sheet metal, pushing it into a gap in the bottom tooling forming a channel in the sheet, at this point two opposed elements in the bottom tooling are forced towards each other forming an overcast channel in the sheet all of these movements are performed and controlled hydraulically and bear no likeness to previous all mechanical tools, also no likeness is given to the finished panel other than its similar use.
