NOTES:
Top values based on allowable stress (ASD). Bottom values based on a deflection limit of L/180. “-” denotes that the allowable load is limited by the panel stress vs. deflection limit.
Steel conforms to ASTM A653 (Galvanized) or ASTM A792 (ZINCALUME) structural steel. Tabulated values are for positive (inward) uniform loading only.
Values are based on the American Iron and Steel Institute “Cold Formed Steel Design Manual” (AISI S100-12). Refer to ascbp.com for more complete 2 1/2" Corrugated performance data.
