Product information

Product name:

West Fraser™ LVL

Product description

The product is a laminated veneer lumber (LVL) (see Figure 1) that is manufactured by laminating veneers of Lodgepole pine, Douglas fir, aspen and white spruce singularly or in combination at the Rocky Mountain House plant. The grain of the veneer is oriented parallel to the length of the member. The 3-mm-thick veneers are bonded with an exterior-type phenolic resin (phenol formaldehyde) complying with CSA O112.10-08, “Evaluation of Adhesives for Structural Wood Products (Limited Moisture Exposure)” (see CCMC 13192-L). The veneer joints are scarfed or lapped and staggered with a minimum distance between joints of not less than 100 mm. The lengths and widths are cut in square edges.

Five grades of the product (1700Fb-1.3E, 2750Fb-1.7E, 3000Fb-1.8E, 3000Fb-1.9E, and 3100Fb-2.0E) are available in 25.4-mm to 89-mm thicknesses, 89-mm to 1 219-mm depths, and a maximum length of 24.38 m.

Quality control and testing is conducted by APA – The Engineered Wood Association (APA-EWS) as an independent third-party monitoring and inspection agency accredited by the Standards Council of Canada.

Manufacturing plant

This certification is valid only for products produced at the following plant:

  • Rocky Mountain House, Alberta, Canada

  Conditions and limitations

The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.

  • The product, as with all SCL, is intended for dry-service applications only.Footnote (1)
  • The product is intended for use in construction as an alternative material to lumber. Proprietary design values presented for the product are to be used by professional engineers for design in accordance with CSA O86-09, “Engineering Design in Wood,” for structural applications such as beams, headers, joists, rafters, and columns as intended by the product manufacturer. The specific application must be qualified through specific testing and validated by the manufacturer. Applications such as I-joist flanges, studs and metal-plated truss chords are beyond the scope of this evaluation.
  • The pre-engineered tables in the literature outlined below have been provided to the CCMC by the manufacturer to demonstrate compliance with Part 9 buildings for acceptance by the local authority having jurisdiction (AHJ):
    1. Manufacturer’s pre-engineered tablesFootnote (2)
      • When the product is used as floor beams in simple spans supporting uniform loads only, the installation must be in accordance with the content of the manufacturer’s publications entitled:
        1. West Fraser™ LVL User’s Guide,” dated April 2015 (0415 CDN);
        2. “West Fraser LVL Supplement to User’s Guide,” dated April 2015 (0415 CDN – SUP).
      • The product must be installed in accordance with the manufacturer’s installation guidelines noted in this document for those applications falling within the scope of the document. Applications outside the scope of these installation guidelines require engineering on a case-by-case basis.
    2. Manufacturer’s installation details
      • Nails and bolts in the attachment of the product must be used and installed in accordance with the manufacturer’s size and spacing specifications.
      • The ends of all beams must be restrained to prevent rollover.
      • The compression edges of all beams must be continuously laterally supported.
    3. Engineering required
      • For structural applications beyond the scope/limitations of the above-referenced publication, or when required by the AHJ, the drawings or related documents must bear the authorized seal of a professional engineer skilled in wood design and licensed to practice under the appropriate provincial or territorial legislation.
      • The product must be designed in accordance with the requirements of CSA O86 and Part 4 of Division B of the NBC 2010. The specified strengths and fastener limits for the product must not exceed the values set forth in the Product specified strengths for dry-service conditions and Product fastener capacities tables in this evaluation.
      • The engineer must design in accordance with CSA O86, and may use as a guide, the “Engineering Guide for Wood Frame Construction,” published by the Canadian Wood Council

Administrative information

Disclaimer

This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:
