Product nameRigidLam® LVL
The product is a laminated veneer lumber (LVL) that is manufactured by laminating 2.54-mm- or 3.175-mm-thick veneers of a single wood species or species combination that meets the requirements specified in the manufacturer’s quality control manual and manufacturing standard. The veneers are laminated with the grain parallel to the length of the member using a phenol-formaldehyde adhesive.
The product is produced in thicknesses ranging from 31.75 mm to 44.45 mm and depths ranging from 89 mm to 610 mm. The 31.75-mm to 44.45-mm billets may be glued together to form up to 178-mm-thick beams.

When the product is used as a joist in simple and multiple spans supporting uniform loads only, the installation must be in accordance with the content of the Roseburg Forest Products’ publication entitled, “Design Guide – Engineered Wood Products, Limit States Design,” dated August 2012.
The product must be installed in accordance with Roseburg Forest Products’ installation guidelines noted in the document for those applications falling within the scope of the document. Applications outside the scope of the installation guidelines require engineering on a case-by-case basis.
- Roseburg’s installation details
The product must be installed using nails and bolts in accordance with the manufacturer’s size and spacing specifications.
The ends of all the beams must be restrained to prevent rollover.
The compression edges of all the beams must be continuously laterally supported.
- Engineering required
For structural applications beyond the scope/limitations of the above-referenced Roseburg Forest Products’ 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 tables "Specified strengths (MPa) and modulus of elasticity (MPa) of the product" and "Relative density (or specific gravity) for fastener design for the product".
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.

This evaluation is applicable only to this product when labelled with the APA EWS certification mark and the phrase “CCMC 13310-R” on each member.
The manufacturing quality assurance program has been adapted to include requirements specified in ASTM D 5456-07, “Standard Specification for Evaluation of Structural Composite Lumber Products,” and is verified by APA – The Engineered Wood Association as part of the product certification. APA – The Engineered Wood Association conducts monthly audits of the manufacturing plants and the quality assurance program.
The design values specified in this evaluation were obtained from testing in conformance with ASTM D 5456-07 and are summarized below. The manufacturer’s published pre-engineered beam and header spans were designed in accordance with CSA O86-09.
|Bending||Specimens were tested in edge and plank bending to establish the characteristic value and volume adjustment exponent. Qualification test data was used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.|
|Shear||Specimens were tested in shear to establish the characteristic value. Qualification test data was used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.|
|Compression parallel to grain||Specimens were tested to establish the characteristic value. Qualification test data was used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.|
|Compression perpendicular to grain||Specimens were tested in edge and plank compression to establish the characteristic value. The characteristic value was multiplied by 1.09 to establish the specified strength in accordance with CSA O86.|
|Tension parallel to grain||Specimens were tested to establish the characteristic value and volume adjustment exponent. Qualification test data was used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CSA O86 was used to determine the specified strength.|
|Nail withdrawal||Nail withdrawal values were established following ASTM D 1761-06, “Standard Test Methods for Mechanical Fasteners in Wood,” for an 8d common nail having a 38-mm penetration. Specimens were tested and an equivalent species capacity was determined in accordance with ASTM D 5456-01, A2.|
|Nail bearing||Nail bearing strength was determined in accordance with ASTM D 5764-97a(2007), “Standard Test Method for Evaluating Dowel-Bearing Strength of Wood and Wood-Based Products,” with 10d common nails with a nominal diameter of 3.76 mm. Specimens were tested and the mean bearing capacity was used to establish the equivalent species capacity as per ASTM D 5456-01, A2.|
|Bolt bearing||Bolt bearing capacity was determined in accordance with ASTM D 5764 with 13-mm and 19-mm bolts. Specimens were tested and the mean bolt bearing capacity was used to establish the equivalent species capacity in accordance with ASTM D 5456-01, A2.|
|Creep and recovery||The SCL specimens were subjected to a 90-day creep test for duration of load for verification of equivalency to lumber in accordance with the principles of ASTM D 6815-09, “Standard Specification for Evaluation of Duration of Load and Creep Effects of Wood and Wood-Based Products.” The criteria were met and the specimens deemed equivalent to lumber.|
|Adhesive||The phenol-formaldehyde adhesive complies with CSA O112.6-M1977, “Phenol and Phenol-Resorcinol Resin Adhesives for Wood (High Temperature Curing).”|
