- 9 - ABSTRACT OF THE DISCLOSURE. PROFILED SHEET MATERIAL. The profiled sheet material is formed into side panels and floor or deck panels for use for example in the manufacture of high-sided lorries, trailers and containers One object of the invention is to provide a profiled side which will present a substantially smooth outer surface and another is to provide a floor or deck of shallow depth but relatively high strength. The profiled sheet material (10) has a plurality of parallel deformations (11) which in cross section are substantially triangular with the base (12) of each deformation spaced from the body (3) of the sheet, The apex (14) of each deformation is formed by closely abutting curved faces of the sheet material (10) where the body of the sheet material is bent into the deformation, This sheet is used as a side plate. Floor or deck plates incorporate strips of timber (50) whose longitudinal faces are tapered. These are located between adjacent pairs of deformations (11) with the tapered faces abutting the respective sides (42, 43) of the deformations. One method of forming the profiled sheet material (10) comprises the steps of passing the sheet material into a press to form a series of U- shaped channels (Fig. 3) therein one at a time. A series of indents (41) are also formed along the length of the web (12) of the U-formation. The U-formation is then deformed by pressing the tops of both limbs (42, 43) inwardly towards each other to form a triangular formation.
