What Is Oil Canning?

Oil canning refers to the perceived waviness or warping in flat areas of a metal panel or coil, an inherent characteristic in light-gauge, cold-rolled flat metal products. It’s is caused by various stresses within the metal itself. This problem can occur in any type of metal material including:

  • Steel
    • Galvalume®
    • Galvanized
    • Stainless
  • Copper
  • Zinc
  • Aluminum
