While the effect is largely a cosmetic concern, understanding its root causes is essential for architects, engineers, and contractors who specify and install metal building components. Recognizing the difference is vital for warranty claims and maintenance; a qualified metal contractor can assess the surface and determine if the distortion is a result of the material’s inherent characteristics or if there has been a breach in the installation protocol.
Understanding and Identifying Visual Oil Canning Patterns
To mitigate this, best practice involves supporting the full width of the panel during handling and allowing for thermal movement through the proper use of slip-critical fasteners and oversized holes. 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.
Mitigation Strategies and Best Practices While it is impossible to eliminate the physics of elasticity entirely, there are effective strategies to minimize the visual impact. The manufacturing process, specifically the level of care taken during coil slitting and edge trimming, can introduce or alleviate stress concentrations.
Understanding and Reducing Visual Oil Canning Patterns
The Physics Behind the Wavy Appearance The phenomenon is a result of elastic strain energy within the metal sheet. Bending or kinking panels on-site, using excessive force to fit panels into position, or over-tightening clips and fasteners can transfer stress into the sheet.
