NOTES:
1. Spans shown are based on transverse load testing per ASTM E 72 and strength of fastening patterns.
2. Spans calculated with 26 gauge exterior and interior facings.
3. The lowest allowable load between panel design and connection strength must be used to determine maximum span.
4. Fastening calculated with 1/4-14 Tek 3 for 16 gauge and 12 gauge purlins. 1/4-20 Tek 5 for 3/16" thick purlins.
5. Deflection limit: L/240
6. Safety Factor = 2.5 for buckling, 3.0 for shear, 3.0 for fastening.
7. Structural capacity of purlins have not been considered.
8. Thermal effect due to temperature differentials have not been considered.
9. Consult your Metal Sales representative for project specific requirements.
10. Consult your Metal Sales representative for FM Global Loss Prevention Data Sheet 1-28 requirements.
