Oil canning is a moderate deformation or buckling of sheet material, particularly common with flat sheet metal surfaces. It is seen as waviness in the flat areas of the metal roof or wall material. Oil Canning is inherent in all sheet metals and is the result of a combination of factors. There are no industry standards for what is excessive oil canning, but there are specific methods and practices that will help minimize the chance of oil canning development. Please keep in mind that doing one or more of these recommendations does not mean you won’t have oil canning; sometimes it’s just an inherent and unavoidable variable with metal. But you can: Purchase a thicker metal material | Install the metal panels on a level, consistent, and in-plane roof deck | Use a low-gloss or matte finish to reduce reflectivity | Install panels with narrow widths
