Oil Canning
All flat metal surfaces can display waviness commonly referred to as
“oil canning”. “Oil canning” is an inherent characteristic of steel products, not a defect, and therefore is not a cause for panel rejection.

NOTES:
The information in these tables applies to uniform loads only.
Upper values based on allowable panel strength.
Bottom values based on allowable service load deflection of L/180. Steel conforms to ASTM A792 (ZINCALUME®) 50,000 psi minimum yield. Values are based on S100-16/S1-18.
Maximum allowable outward load capacities are shown and dependent upon fastener-to-substrate capacities. Refer to IAPMO-UES report #ER-0309 for specific product capacities.
