Zusammenfassung:	A method of making grating wherein grating bars are provided with an anti-slip coating. The grating bars are placed side by side with their top edges aligned and with the sides of adjacent bars in contact with each other. The grating bars are held stationary relative to each other. Molten metal is sprayed on to the top edges to form a rough surface on the top edges. The grating bars are subsequently separated and assembled together in a spaced relationship by attaching transversely extending members to the grating bars.
