When a flat panel is formed from a coil of metal, it retains internal stresses from the rolling and leveling process. Furthermore, thermal movement can exacerbate the issue; as metal expands and contracts, the stress on the fasteners and the panel’s attachment points can induce additional movement.
Effective Metal Panel Oil Canning Solutions and Prevention
This is not a failure of the material’s strength but rather a release of tension across the width of the sheet, governed by the metal’s modulus of elasticity and its geometric configuration. The most significant is the thickness of the substrate; thinner gauges are more prone to visible distortion because they have less inherent rigidity.
The profile of the panel also plays a critical role—long, uninterrupted spans with minimal structural support, such as those found in standing seam roofs or wall panels, provide the perfect conditions for wave formation. Aesthetic Considerations and Perspective.
Understanding Metal Panel Oil Canning Solutions
The manufacturing process, specifically the level of care taken during coil slitting and edge trimming, can introduce or alleviate stress concentrations. Unlike dents or creases, which are permanent plastic deformations caused by physical impact, the waves of oil canning are flexible and will not hold a new shape if pressed.
