A flat blank (1) of material, is formed of corrugated cardboard or plastics material. The blank (1) forms, when assembled, a structural element including a number of wall forming panels (2, 3, 4, 5) delimited by a set of transverse fold-lines and having at least two flaps (6, 7) which provide a diagonal cross-brace. The structural element may be formed as a separate component or as an integral part of a larger structure such as a pallet or box.
