Product information

Product name

Global LVL

Product description

The product is a laminated veneer lumber (LVL) that is available in several structural grades as outlined in the tables in this evaluation. The LVL product is manufactured by laminating veneers of either:

  • all aspen veneers, or
  • a mixed species of aspen/birch veneers.

The grain of the veneers is oriented to the length of the member. The 3.2-mm-thick veneers are bonded with a phenol-formaldehyde adhesive and laid end to end with a slight overlap. Veneer layers are laid one on top of the other such that the scarf and lap joints in one layer are staggered in relation to those in the adjacent layer. The veneer assembly is hot pressed under computer-controlled time, pressure and temperature cycles. The product is then machined to the required depth and length after curing.

The product is available in thicknesses ranging from 19 mm to 76 mm, depths ranging from 45 mm to 1 220 mm, and lengths up to 18 m.

The phenol-formaldehyde adhesive complies with CSA O112.10-08, “Evaluation of Adhesives for Structural Wood Products (Limited Moisture Exposure)” (CCMC 14111-L).

    The specified strengths and fastener limits for the product must not exceed the values set forth in the "Technical Information" section of this evaluation.

    When the product is used as a beam member, the ends of all beams must be restrained to prevent rollover. This is normally achieved by attaching a diaphragm sheathing to the top or to the compression edge, and to an end wall or shear transfer panel capable of transferring a minimum unfactored uniform load of 730 N/m or the required shear forces due to wind or seismic conditions. Blocking or cross-bracing with equivalent strength may be used. For beams with a maximum depth-to-width ratio of no more than 6.5:1, the compression edge of the beams must be laterally supported at least every 610 mm. When the depth-to-width ratio exceeds 6.5:1, the compression edge of the beams must be continuously laterally supported through its length, except where the design is done in accordance with CSA O86.

This evaluation is applicable only to Global LVL labeled with the APA–EWS certification mark and the CCMC 13543-R on each beam or header member.

The manufacturing quality assurance program has been updated to include requirements specified in the most recent version of ASTM D 5456, “Evaluation of Structural Composite Lumber Products,” and has been verified by APA-EWS as part of the product certification. APA-EWS conducts audits of the manufacturing plants and the quality assurance program.

Appendix A

The design values are obtained from testing to ASTM D 5456-01, “Evaluation of Structural Composite Lumber Products,” was used for original qualification and volume effect exponent determination. The ASTM D 5456-07 was used for the plant re- qualification for the strength of the old and new grades, as specified in CAN/CSA O86-09 and summarized below. The original exponents for volume adjustments being used was reaffirmed by the certification agency to ASTM D 5456-13a.

Table 7. Additional test information for Global LVL
Property Test Information
Bending A total of 216 specimens were originally tested in edgewise and flatwise bending. Qualification test data was used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CAN/CSA O86 was used to determine the specified strength. For requalification, 53 specimens of 2850Fb-1.9E (edgewise) and 3300Fb-2.0E (edgewise) grades were tested. For new qualification, 53 specimens of 3025Fb-1.9E (edgewise) and 2800Fb-1.7E (edgewise and flatwise) grades were tested.
Modulus of elasticity

Shear-free modulus of elasticity was established during the initial qualification. Testing and analysis by APA following the procedures of Sections 45 through 52 of Appendix X4 of ASTM D 198-15, “Standard Test Methods of Static Tests of Lumber in Structural Size,” was conducted to determine Etrue/Eapparent for 3300Fb-2.0E. Ratios of 1.08 and 1.10 were determined for edgewise bending and flatwise bending, respectively. The conservative ratio of 1.10 was selected for all grades and species to determine Eapparent.

The corresponding conservative Etrue/G ratio of 40 was selected for the derivation of the deflection equation instead of the typically assumed ratio of 16.

Shear A total of 240 specimens were originally tested parallel and perpendicular to grain as well as to the glue line to establish the characteristic value. Qualification test data was used to establish the applicable coefficient of variation, CVw, and the reliability normalization factor from CAN/CSA O86 was used to determine the specified strength. For requalification, 53 specimens of 2850Fb-1.9E and 3300Fb-2.0E grades were tested in both plank and the flatwise orientation. For new qualification, 53 specimens of 3025Fb-1.9E (plank only) and 2800Fb-1.7E grade were tested in both plank and the flatwise orientation.
Compression parallel to grain A total of 60 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 CAN/CSA O86 was used to determine the specified strength. For new qualification, 53 specimens of 2800Fb-1.7E were tested and no specimens of 3025Fb-1.9E were tested.
Compression perpendicular to grain A total of 120 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 CAN/CSA O86. For new qualification, 30 specimens of 2800Fb-1.7E were tested and no specimens of 3025Fb-1.9E were tested.
Tension parallel to grain A total of 184 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 CAN/CSA O86 was used to determine the specified strength. For requalification, 53 specimens of 2850Fb-1.9E and 3300Fb-2.0E grades were tested. For new qualification, 53 specimens of 3025Fb-1.9E and 2800Fb-1.7E grades were tested.
Nail withdrawal Nail withdrawal values were established following ASTM D 1761-06 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, A2. For new qualification, 15 specimens of 2800Fb-1.7E grade were tested.
Nail lateral resistance Dowel bearing strength was determined in accordance with ASTM D 5764-97a(2007) 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, A2. For new qualification, 15 specimens of 2800Fb-1.7E grade were tested.
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, A2. For new qualification, 15 specimens of 2800Fb-1.7E grade were tested.
Creep and recovery In the initial qualification, 30 specimens of mixed birch/aspen were tested within a four-month creep and recovery test program, resulting in acceptable performance demonstrating equivalency to the duration of load behaviour of lumber.
Product durability The SCL product durability was tested as per Annex A4.3 of a more recent edition of ASTM D 5456-09, not currently required in the 2007 version specified in CAN/CSA O86-09.
Adhesive The adhesive used is a high-temperature cure phenol-resorcinol that has demonstrated compliance with CSA O112.10-08 (CCMC 14111-L).
Quality assurance The manufacturing quality assurance program includes audits by APA-EWS that are conducted as part of the product certification.
