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. The metal surface buckles slightly into a series of gentle waves, creating the ridges and valleys that catch light differently.

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. 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.
Specifying a thicker gauge of metal is the most direct solution, though it may affect cost and weight. 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.
Understanding Oil Canning as a Non-Material Failure
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. If the panel is not allowed to fully relax or if it is overstretched during handling, these stored energies seek balance.
