Structural 1 Rated Sheathing: Roofing

Bending Strength for Structural 1 (15.9mm) Panel with Support Spacing ‘Roof-48’

General Info: Structural 1 indicates a performance-rated panel, with superior bending stiffness and strength
Bending strength  – stress applied parallel: Factor of safety (F S) – 1,000 (lb-in²/ft of panel width) when stress applied parallel to strength axis. The strength axis is always parallel to the face and back orientation of the strands unless otherwise indicated
Bending strength  – stress applied perpendicular: Factor of safety (F S) – 607.5 (lb-in²/ft of panel width) when stress applied perpendicular to strength axis
Bending stiffness – stress applied parallel to strength axis: N/A
Bending stiffness – stress applied perpendicular to strength axis: N/A
Span rating/support spacing: Roof-48
Thickness/US Performance Category*: 18.2mm (min 17.47mm; max 19.05mm); (23/32)*
