A structural panel, suitable for use as slatwalling in retail outlets, comprised of a metal sheet bent to define on each side of the panel a series of channels of re-entrant cross-section extending continuously across the width of the panel. The panel is manufactured by a bending process wherein a portion of sheet material is deformed into a U-shaped cross-section, and the sides of the channel are deformed by bending into a substantially S-shape to define the re-entrant channel shape, this process being repeated at regular intervals along the sheet material. The bending process is performed by tooling including first and second tool assemblies, the first assembly including a shaping part for deforming a portion of sheet material into a recess defined between a pair of opposed tool elements of the second tool assembly, the opposed tool elements being driven towards each other to deform the channel side walls into an S-shape. |

DETAILED DESCRIPTION In accordance with one aspect the invention resides in a structural panel formed from sheet material, the sheet material being bent to form on each face of the panel a series of parallel channels with the same re-entrant cross-sectional shape.
In a preferred construction each of the side walls of each channel is defined by a metal section of substantially S-shaped cross-section.
Furthermore, the channels on one side of the panel have the same cross-sectional shape as those on the other side of the panel, enabling similar support members to be attached to both sides of the panel.
This enables a single structural panel to be utilised in assembly of a partition wall structure to be positioned within the area of a shop floor and allowing products to be easily supported on and displayed to both sides of the partition wall.
In accordance with a second aspect the invention provides a method of bending sheet metal in the production of a sheet metal panel having channels extending across the width thereof, wherein a sheet portion is deformed by bending into a substantially U-shaped cross-section to form the base of a channel and two opposed sides, and the sides are deformed by bending into substantially S-shape to form a channel with a re-entrant cross-section.
In the manufacture of a metal slatwall panel as provided in accordance with the invention, the bending process is repeated at regular intervals along the sheet to define a series of parallel channels of essentially the same cross-section.
Preferably the bending and shaping tools used in the process are so configured that between adjacent channels formed by the method described above are defined channels of substantially equal cross-section but open to the opposite face of the panel.
The invention also resides in tooling for carrying out the process including two tool assemblies, the first assembly including a shaping part for deforming the sheet portion into a recess defined between a pair of opposed tool elements of the second tool assembly, thereby to deform the sheet portion into a channel of U-shaped cross-section, the tool elements of the second assembly being movable towards each other for deforming the side walls of the channel into substantially S-shape
