If the panel is not allowed to fully relax or if it is overstretched during handling, these stored energies seek balance. Differentiating from Other Defects It is important to distinguish oil canning from other forms of surface imperfection.
How Overstretching Panel Causes Oil Canning
Aesthetic Considerations and Perspective. Primary Causes in Architectural Metal Several factors contribute to the severity of oil canning in architectural applications.
Oil canning is a visual phenomenon observed primarily in sheet metal construction, where flat surfaces develop a subtle, wavy distortion that resembles the rippled texture of an oil can. 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.
How Overstretching Panel Causes Oil Canning
When a flat panel is formed from a coil of metal, it retains internal stresses from the rolling and leveling process. 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.
