Our standing seam panels can be manufactured with a variety of surface profiles designed to improve panel rigidity and help prevent oil‑canning, the visible waviness that can appear in flat metal surfaces due to expansion, contraction, or installation stresses. Adding surface profiles introduces subtle breaks in the pan that diffuse light and reduce reflective distortion, creating a smoother, more consistent appearance across the roof or wall. For the greatest stability and the most effective oil‑canning prevention, striations are the preferred choice due to their high level of rigidity.
