The second span table is the same as the first. The first span table is for roofs where the ceiling is not attached to the rafters (with no snow load), a live load of 20 Psf, a dead load of 20 Psf, and a deflection limit of L/180. BlueLinx offers a full line of depths matching our onCENTER BLI joist offering. Rafters with ceiling not attached to rafters, ground snow load 50 Psf, dead load 20 Psf, deflection limit L/180. They only show the most restrictive of simple or multi span. Spans based on L/480 deflection and desgin loads of 40 PSF live and 10 PSF dead. Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans. Manufacturing quality is monitored by the third-party inspection services of APA- EWS® and backed by a lifetime limited warranty.Ĭertified as APA® Performance Rated, onCENTER Rim Board encloses BLI joist floor systems, providing a flush perimeter edge with high vertical-load transfer capabilities. The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries. BLI joists are manufactured with low-moisture content material ensuring floor systems that are quieter, with greater stability and long-term dependability. Distributed exclusively by BlueLinx, onCENTER Engineered Lumber provides long-lasting, consistent performance. As moisture evaporates from ordinary lumber, nails can pop and squeak resulting in costly call-backs and repairs.
