Design Considerations:
Light gauge steel cladding with wide flat pans may exhibit oil canning which can affect the aesthetics of the building design.
Oil canning will vary depending on the time of day and angle of viewing and is usually more noticeable in darker colours.
Oil canning will also be more prevalent in wider pans and longer sheet runs. Building designers and homeowners should be aware of this and take this into consideration.
