Rated Sheathing 21.6mm Panel: Bending Strength & Stiffness with Support Spacing ‘Floor-32’
| General info: | APA Rated OSB Sheathing always has a bond durability classification of Exposure 1 as not for exterior use. Panels have one surface with an overlay, texturing or grooving. Creating the tongue reduces the panel width by approximately 12.5 mm (1/2”), so net width may be 1,206mm (47.5 in) |
| Bending strength – stress applied parallel: | Factor of safety (F S) bending strength – 1,050 (lb-in²/ft of panel width) when stress applied parallel to strength axis. This 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) bending strength – 685 (lb-in²/ft of panel width) when stress applied perpendicular to strength axis |
| Bending stiffness – stress applied parallel: | E I (lb-in²/ft of panel width) – 650,000 when stress applied parallel to strength axis. E I provides a measure of the resistance of the beam to bending. The larger the E I, the smaller the deflection |
| Bending stiffness – stress applied perpendicular: | E I – 235,000 when stress applied perpendicular to strength axis |
| Span rating/support spacing: | Floor-32 |
| Thickness/US Performance Category*: | 21.6mm (min 21.1mm; max 23.34mm); (7/8)* |
