Definition of Oil Canning [In Under 100 Words]

The word "oil canning" is frequently used in the metal roofing and wall system industry. Check out this article for the true definition (in under 100 words) of this visual phenomenon.


What is oil canning?

Oil canning is a visual phenomenon consisting of waviness or distortion in the broad, flat areas of a metal panel and is an inherent characteristic of light-gauge, cold-rolled flat metal products. Oil canning is considered a cosmetic, surface-level issue that doesn’t affect the structural integrity of the panel system.

There are many different causes of oil canning, including stresses inflicted on the metal, color and gloss type, incorrect installation, misalignment of the panels, and structural changes. 

Check out this article for an in-depth and thorough explanation of oil canning and how it can be minimized.
