Contact Enduro for SERIES FM Loads/Span Data
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

DESIGN PARAMETERS

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.

LOAD/SPAN TABLES

The load/span tables shown in this Guide are developed using the following maximum deflections limits and Factors of Safety (FOS), unless otherwise noted:

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.
