The invention relates to a casting roll or a casting strip of a co-acting cold mold of a strip casting plant for producing an aluminum alloy strip; the invention further relates to strip casting equipment for manufacturing the aluminum alloy strip. The strip casting equipment comprises at least one synchronous cold mold with a casting gap. The invention further relates to a method for producing an aluminum alloy strip by means of a strip casting plant. The aim of the invention is to provide a casting roll or a casting strip or a strip casting system, by means of which, on the one hand, adhesion to the casting roll or the casting strip during strip casting can be avoided and, on the other hand, a low-segregation and crack-free aluminum alloy strip can be produced, in particular under industrial conditions, this object is solved by a specific surface structure in that the surface of the cast roller or cast strip has a roughness value Sa greater than 5 [mu] m and an average peak number RPc (0.5 [mu] m) less than
