If the panel is not allowed to fully relax or if it is overstretched during handling, these stored energies seek balance. The metal surface buckles slightly into a series of gentle waves, creating the ridges and valleys that catch light differently.
Understanding Oil Canning Thermal Movement Allowance
When a flat panel is formed from a coil of metal, it retains internal stresses from the rolling and leveling process. Differentiating from Other Defects It is important to distinguish oil canning from other forms of surface imperfection.
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. Primary Causes in Architectural Metal Several factors contribute to the severity of oil canning in architectural applications.
Understanding Oil Canning Thermal Movement Allowance
Architectural designers can incorporate intermediate supports, such as sub-girts or batten strips, to reduce the effective span length of the panels. 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.
