INSTALLATION GUIDE US 2018
P3 JOIST Storage and Handling Guidelines 1. Store, stack, and handle P3 Joists in a vertical and level position only. 2. Do not store P3 Joists in direct contact with the ground; do not store P3 Joist flatwise. 3. Protect P3 Joists from weather, and use stickers to separate bundles. 4. To protect P3 Joists further from dirt and weather, do not open bundles until time of installation. 5.
Allowable Floor Spans Maximum Allowable Spans NOTES 1. Allowable clear span is applicable to simple-span or multiple-span residential floor construction with a design dead load of 10 psf and a live load of 40 psf. The live load deflection is limited to L/480. (L = span length in inches). Spans are based on duration factor (LDF) of 1.0. 2.
