What causes oil canning? Oil canning is caused by differential stresses within the metal. As the metal tries to relieve these stresses in panels with high width to thickness ratios, the material buckles out of plane producing the characteristic waviness of oil canning. Stresses may be introduced at a several stages in panel manufacturing. 1.
