Structurally defined continuous metal strips are formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. The surface of the chill body (chill surface) whereon casting of the strips takes place has a contoured surface, i.e. it is provided with structurally defined protruberances and/or indentations, which are faithfully replicated by the formed strip, the thickness of the strip being substantially uniform throughout, regardless of whether it replicates a level area of the chill surface or a raised or indented area.
