Abstract (en)
[origin: WO2012098060A1] The invention relates to an exterior wall metal sheet or strip made of aluminium or an aluminium alloy of the type AA 5005 and a process for the production thereof. The problem of providing an alternative to the steel sheets used hitherto in the field of exterior walls of buildings is solved according to the teaching of the present invention by an exterior wall metal sheet or strip made of aluminium or an aluminium alloy of the type AA 5005 by means of the exterior wall metal sheet having a thickness of from > 2 mm to 4 mm and an average roughness Ra of from 1.2 to 1.7 µm, where the average peak-to-valley height Rz is from 7 to 12 µm measured in accordance with DIN EN ISO 4287.
