One of the local cladding materials where I have been living is corrugated steel, borrowed from the agricultural industry that uses it for a range of storage buildings. Most of these are circular in plan and so only have one sort of joint and no corner detail. When it is used for rectangular buildings it normally has a folded angle cover strip over the corner junction. I was looking at some German aeroplanes, built during the lead up to the second world war, that have corrugated skins to see how else to treat the detailing of such a material (aluminium in the case of the aeroplanes). The use of corrugated skins on aeroplanes seems strange, providing little torsional rigidity and a large surface area for drag, but the detailing is very careful. One of the examples is from the Western Canada Aviation Museum in Winnipeg and the other from Duxford near Cambridge in the UK. I have a few more pictures, including some interior shots, so I may post some more another day. The crimped edge seems to provide a much greater range of joint possibilities. I was thinking of using corrugated steel for the cladding of a house I was working on and looked at these ‘planes to help work out a range of scale when detailing the skin.
