Problems that naturally occur as solid sawn lumberdries twisting, splitting, checking, crowning and warping are greatlyreduced. And pound for pound, LP LVL has more load-carrying capacitythan solid sawn lumber. The end result: a building material that is morereliable, high-performing and usable than traditional lumber. And unlikeanything available with traditional commodity products, LP LVL isbacked by a limited lifetime Strength is in the EngineeringLP LVL is made from ultrasonically and visually graded veneersarranged in a specific pattern so that naturally occurring defectshave no concentrated effect on the beam s performance.

2 The veneersare then bonded with waterproof adhesives under pressure and LVL beams are exceptionally strong, solid and straight, makingthem excellent for most primary load-carrying beam , unlike traditional solid sawn beams, LP LVL is available incustom lengths and LVL: Available in Four GradesLP LVL is available in four grades: , , and It comes in a wide variety ofthicknesses and depths, and lengths of up to 60 feet. In addition tothe standard natural finish, a water-resistant coating called SiteCote is available for extra weather protection during construction. Somegrades are available in factory-laminated widths (known as billetbeam ) to eliminate the need for field nailing and/or bolting ofmultiple for Easy, Reliable DesignOur Design /specification software enhances your in-house designcapabilities.

Code Evaluation LP LVL has been evaluated by the Canadian Construction MaterialsCentre (CCMC) to comply with the intent of the National BuildingCode of Canada (NBC).

5 Keep LP LVL dry. These products are intended to resist the effects of moisture on structural performance from normalconstruction delays but are not intended for permanent exposure to the weather. Unload products carefully, by lifting. Support the bundles to reduce excessive bowing. Individual products should behandled in a manner which prevents physical damage during measuring, cutting, erection, etc. Keep products stored in wrapped and strapped bundles, stacked no more than 10' high. Support and separate bundleswith 2x4 (or larger) stickers spaced no more than 10' apart. Keep stickers in line vertically. Product must not be stored in contact with the ground, or have prolonged exposure to the weather.

6 Use forklifts and cranes carefully to avoid damaging product. Do not use a visually damaged product. Call your local LP Engineered Wood Products distributor for assistance whendamaged products are encountered. For satisfactory performance, LP LVL must be used under dry, well-ventilated conditions. Check that LVL plies are dry before nailing or bolting together to avoid trapped moisture. Do not use LP LVL for other purposes, such as ramps, planks, 3/16/06 8:11 PM Page 44LP Product Name or Generic Descriptor 2006 Louisiana-Pacific CorporationLP LVL Specifications & Design Values IMPORTANT NOTES1.

Make sure that the Design loads, duration of load increases and deflection limits that you choose from this brochure are appropriate for your application and comply with code requirements in the area where the product is to be If you do not know the correct Design criteria and all the loads imposed on the component from all parts of the structure, seek qualified help from the architect, engineer or designer of the Additional reference data on wood construction is available in the form of building codes, code evaluation reports and other Design LP LVL beams shall be used under dry, well ventilated and covered conditions. Dry conditions are product installation conditions where ambient moisture content is 16% or LP LVL beams are not The tables and Design values listed in this guide require continuous lateral restraint of the compressionedge of LVL beams.

8 Continuous restraint is defined as a maximumunbraced length of 24". This restraint is normally provided by sheathing and/or framing members, which must be adequately anchored to the beam and the supporting structure. Framing conditions that do not provide continuous lateral restraint require special Design . Contact your LP Engineered Wood Products distributor. Caution: Failure to provide adequate lateral restraint could result in unstable beams and reduced load Lateral restraint must also be provided at bearings or supports to prevent beams from rotating or Beam spans are measured from center-to-center of supports. A structurally adequate bearing surface under the full width (thickness) of the beam must be provided at each Minimum bearing length is 1-1/2" (at least one jack stud or cripple is required).

9 Refer to bearing chart and notes for quick reference tables. Additionally, verify local code requirements concerning minimum Refer to Connection of Multiple Ply Beams for appropriate multi-ply For nails installed on top or bottom edge of beam: closest on-center nail spacing per row is 3" for 8d (2-1/2") common nails and 4" for 10d (3") common Tables in this brochure are for simple (single) span beams as noted, and for continuous (multiple) equal span beams as Tables in this brochure are for uniform (evenly distributed) loads along the length of the For other conditions such as concentrated loads, unequal spans, etc., contact your LP Engineered Wood Products Total load deflections are based on instantaneous Equal or better grades of LP LVL can be substituted for the indicated notched or drilledbeams must be reviewed by a professional engineerSee hole detail on page 30 for allowable hole sizes and locationsDON T notch beam at supportWARNINGThe following condition is NOTpermitted!
