Abstract

The invention discloses a method of forming gratings suitable for use as walkways etc. The method includes the steps of forming transverse bearer bars (1) from strips of flat plate by punching a series of transverse slots across the central axis of each plate, then folding the plates to form U-sections with the slots located in the apices of the U-sections. Longitudinal bars, which are lengths of flat bar, are then inserted as tight press-fits into the slots, and the undersides of the longitudinal bars are deformed laterally between the legs of each U-section to prevent their removal from the slots. A strong lightweight grating results.
