to LVL. Members are available in a variety of widths, depths and lengths, and are primarily used as beams, columns and headers. Laminated strand lumber and oriented strand lumber are manufactured using wood strands combined with an adhesive and are oriented and formed into a large mat and pressed. LSL and OSL are commonly used as beams, headers and studs.
Examples of engineered wood products
SHEET OR PANEL PRODUCTS metal web
Panel products such as plywood and oriented strand board (OSB) are used in wood-frame construction to add rigidity to roof, wall and floor framing, and to provide a uniform surface for the application of roofing, cladding and floor finish materials.

wood I-joist
All these products provide design flexibility by virtue of their longer span capabilities and higher strength compared to dimension lumber. Structural composite lumber (SCL) includes laminated veneer lumber (LVL), parallel-strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL).
Plywood is made of thin layers or plies of wood glued together with the grain direction of adjacent plies perpendicular to each other. Common thicknesses range from 6.0 to 18.5 mm (1⁄4 to 3⁄4 in.). Like dimension lumber, plywood is graded for particular uses. Douglas fir plywood (DFP) and Canadian softwood plywood (CSP) are the most common types of sheathing plywood. All sheathing-grade plywood is made with exterior-grade glue. Overlaid plywood is plywood that is sealed with paper and resin and used for concrete formwork.
Laminated veneer lumber consists of thin veneer panels laid parallel to the longitudinal direction, coated with a waterproof adhesive, and bonded by heat and pressure. Available in a wide variety of sizes and strengths, LVL may be cut into desired lengths for use as beams, columns, headers (lintels), joists and as flanges for wood I-joists.
Oriented strand board (OSB) is a structural panel made from wood strands mechanically oriented in layers, with the outer layers running parallel to the long dimension of the sheet, and the inner layers having a random alignment. OSB is made with exterior-grade glue and is structurally equivalent to plywood. It is primarily used for roof or wall sheathing, sub-flooring, siding and the webs of wood I-joists.
Parallel-strand lumber is manufactured using thin veneer panels cut into narrow strips and then bonded together using a process similar
Waferboard is made of wood wafers that, unlike OSB, are not oriented. It has been replaced by OSB and its availability in Canada is very limited.
