Load/Span Tables are based on full scale tests that consider three design parameters:
- Critical bending moment at actual panel failure
- Flexural stiffness
- Pullover force per fastener of the panel section.
Table values are based upon:
- Roofing: Deflection l/60, FOS 2.5+, 1.88-
- Siding: Deflection L/30 FOS 1.88

The load/span tables
shown in this Guide are derived from large scale tests using full panels
to simulate actual service conditions (at a reference temperature of 77°
F). These tests include two span vacuum box test and three point load
tests.
Each span shown in the load/span tables represents the most conservative
span derived when the panel is assessed using the following parameters:
Design Parameters
- Critical bending moment at actual panel failure;
- Flexural stiffness
factor, EI, (where E is the flexural
modulus of elasticity and I is the moment of inertia of
the panel section); and - Pullover force resistance per fastener.
Panel Roofing:
Positive Loads: Deflection: L/60, FOS:2.5
Negative Loads: Deflection: L/60, FOS: 1.88
Panel Siding:
Wind Loads: Deflection: L/30, FOS:1.88
Roof Deck:
Dead + Live Loads: Deflection: L/180, FOS:2.5 Uplift Loads: Deflection: L/18000, FOS:1.88
The load/span tables are to be used as a guide only as specific environmental conditions are not considered.
Specific applications should be verified by a registered Professional Engineer.
