Oil Canning, Bulging, Warping, Buckling, Dislodgements
Introduction
Type of Building: Commercial building
Oil canning, bulging, warping, buckling, dislodgements are commonly observed on metal claddings especial those with larger panels.
Bulging, warping, buckling, dislodgements, are serious matters as they may have to do with the mechanical anchorages. Such prolonged problems may lead to falling of parts from the facade.
Oil canning refers to the wavy, rippled, or buckled distortion that can appear in the flat areas of metal cladding and roofing panels. This effect is often seen in larger flat sections of materials like copper, aluminum, zinc, and steel. However, it’s important to note that oil canning is not considered a defect in the metal panels but rather an aesthetic issue. Whether it is viewed positively or negatively depends on factors such as the choice of material, finish, panel thickness, panel width, and the manufacturing and installation processes. The visibility of oil canning can also be affected by lighting conditions and temperature changes. It tends to become more noticeable at certain times of day or during specific seasons, particularly when sunlight hits the surface at particular angles or when there is a temperature difference between the metal and the surrounding air. As a result, the appearance of oil canning can vary based on environmental factors.
