1 Structural composite lumber may be made up of a single piece or multiple pieces nailed together per manufacturer's guidelines to make wider beams. Table Specifications: These sizes are for dry service condition of use.
Eighty-five structural-size SCL beams (twenty-nine 1.5E LSL, thirty 1.9E LVL, and twenty-six 2.0E PSL) with nominal dimensions of 44 by 140 by 1524 mm were obtained from TrusJoist A Weyerhaeuser Business. A small piece (76 mrn) was cut from each end of the specimens for shear block tests.
Laminated Veneer Lumber (LVL) LVL is the most widely used of the structural composite lumber products. It is produced by bonding thin wood veneers together in a large billet. The grain of all veneer is parallel to the long direction. The LVL billet is then sawn to desired dimensions depending on the construction application.
Roseburg RIGIDLAM laminated veneer lumber (LVL) is a structural composite lumber product consisting of veneers laminated with grain parallel to the length of the member in accordance with the in-plant manufacturing standard approved by APA.
Structural composite lumber (SCL) is a family of engineered wood products created by layering dried and graded wood veneers, strands or flakes with moisture-resistant adhesive into blocks of material known as billets, which are subsequently resawn into specified sizes.
The concern for environmentally responsible building practices and the ongoing demand for better-quality structural materials have led to the increased reliance on a variety of engineered-wood products known as structural composite lumber, also referred to in the industry as SCL.
Due to its composite nature, it is much less likely than conventional lumber to warp, twist, bow, or shrink. LVL is a type of structural composite lumber, comparable to Glued laminated timber (Gluelam) but with a higher allowable stress.

Although the term engineered lumber is used to describe a variety of materials, most are defined as structural components that have been fabricated. Engineered wood is manufactured by bonding together wood strands, veneers, lumber or other forms of wood fiber to produce a larger and integral composite unit that is stronger and stiffer than the ...
Structural composite lumber, including LVL, are a relatively recent innovation. They are the result of new technology and economic pressure to make use of new species and smaller trees that cannot be used to make solid sawn lumber.
