The manufacturing process, specifically the level of care taken during coil slitting and edge trimming, can introduce or alleviate stress concentrations. Specifying a thicker gauge of metal is the most direct solution, though it may affect cost and weight.
Oil Canning Slip Critical Fasteners: The Role of Coil Processing and Handling
If the panel is not allowed to fully relax or if it is overstretched during handling, these stored energies seek balance. The most significant is the thickness of the substrate; thinner gauges are more prone to visible distortion because they have less inherent rigidity.
The Physics Behind the Wavy Appearance The phenomenon is a result of elastic strain energy within the metal sheet. In the field, installers should adhere to handling guidelines that prevent deformation and ensure that the building envelope is designed to accommodate movement.

The metal surface buckles slightly into a series of gentle waves, creating the ridges and valleys that catch light differently. Primary Causes in Architectural Metal Several factors contribute to the severity of oil canning in architectural applications.
