EACOM SAULT STE. MARIE EACOM Timber Corporation is a major Eastern Canadian wood products company formed in 2008. Its head office is located in Montreal, Quebec, with regional offices located in Timmins, Ontario and Val-d’Or, Quebec. In 2010, EACOM acquired Domtar Forest Products Division. As a result, its operations include the manufacturing, marketing and distribution of lumber and wood based value-added products, and the management of forest resources.
P3 JOIST EACOM Timber Corporation has made it easy to make the right choice for residential and non-residential floor and roof joist products. P3 Joist are produced in accordance with EACOM’s report ICC ESR – 1262, APA’s Product Report L261 and APA’s ICC ESR – 1405. P3 Joist are in compliance with the International Building Code (IBC) and the International Residential Code (IRC) editions 2006, 2009 and 2012. All code reports can be downloaded from our website www.eacom.ca.
P3 JOIST (continued) 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.
Selecting a P3 JOIST Product Description The P3 Joist is an ”I”-shaped engineered wood structural member designed for use in residential and nonresidential floor and roof construction. P3 Joist are prefabricated using SPF MSR lumber flanges and OSB web, which are bonded together with exterior-type adhesives. P3 Joist are limited to a L/480 maximum live load deflection for residential and non-residential floor applications.
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.
