A certain amount of waviness, called “oil canning” is inherent in any product made from coiled sheet metal. Any flat area has the potential for oil canning. Viewing the panels from certain directions and under certain light can reveal stress in the metal known as oil canning. The appearance of waviness, or oil canning, can be caused by the use of lighter gauges, dark colors and framing conditions. Oil canning is cosmetic only and does not affect the structural integrity of the panel and is not cause for rejection.
