Notes
  1. Based on Galvatherm 42 in. wide wall panel with 26 ga. exterior and interior steel facers (min. Fy= 37 ksi as per ASTM A653)
  2. Steel facers are prepainted galvanized steel as per ASTM A653 grade 37 (Fy= 37 ksi min). Elasticity Modulus is 29, 000 ksi.
  3. Load Tables were derived from ASTM E72 structural testing. Allowable loads were obtained with 2.5 bending safety factor 3.0 shear safety factor, and deflection limit of L/180.
  4. Thermal load effect due to temperature differential between exterior and interior facers must be considered when applies.
  5. Allowable load is governed by the lowest value of bending strength, shear strength and deflection limit. For allowable load governed by connection, please contact to the technical department.
  6. Foam Insulation factors are based on nominal initial k factor of 0.116 BTU/ft².h.°F tested as per ASTM C518-04 at a mean temperature of 40°F (4°C)
