Parallel strand lumber

Parallel strand lumber (PSL) is a high strength structural composite lumber product manufactured by gluing strands of wood together under pressure. Advances in timber technology mean more options for architects and designers seeking sturdy materials for structural applications. PSL manufacturing involves little waste, as almost all parts of a log are used in the product.

Laminated Strand Lumber (LSL) is manufactured from flaked wood strands and resembles oriented strand board (OSB) in appearance, though the strands are arranged parallel to the longitudinal axis of the member. Members are commonly fabricated in ¼”, ½”, ¾” and ½” widths, and in ¼”-16” depths to match common i-joists. Phenolic resin is used to bond the individual veneer strips.

The superior strength of Parallam PSL makes longer clear spans possible, giving you more design options with open, spacious floor plans. Parallam PSL beams can be stained or finished for a handsome look in exposed applications. This feature is not available right now.

PARALLEL STRAND LUMBER (PSL). PSL is a high-strength type of structural composite lumber that is made from long strands of veneer that are glued together with high. Parallel-Strand Lumber PSL is similar to LVL in some ways, but very different in others. Current JAS approvals are listed within the manufacturer directory.

Produce odd-shaped strands that are coated in adhesive and cured under pressure. Parallam PSL ( parallel strand lumber ) headers, beams and columns are engineered to support heavier loads than comparably size conventional glulam or sawn lumber products. Parallel Strand Lumber (PSL) Laminated Strand Lumber (LSL) Oriented Strand Lumber (OSL).

Strong and dimensionally stable, Parallam is an ideal choice for load-bearing beams. Bob visits Dave Parker in Vancouver, BC to see how Parallam beams are manufactured. In addition, the struts are manufactured with knockout holes for wiring and piping, reducing construction site labor costs. Under the Parallam trademark, TJ markets its parallel strand lumber (PSL) products. It is a proprietary product manufactured by iLevel by Weyerhaeuser (formerly Trus Joist Macmillan), under the name Parallam.

Since all imperfections of natural wood are remove PSL is more uniform and stronger than solid timber. Like LSL beams and columns, LSL panels (Laminated Strand Lumber ) are made by shredding wood from fast-growing, low-value hardwood logs, such as aspen, birch and poplar into thin strands. Shop Menards for great selection of laminated veneer lumber that can be used as headers or as floor and ceiling beams. PSL can be milled to any dimension from 1×inch up to 2×inch.

Weyerhaeuser Unlike other types of structural composite lumber , parallel strand lumber (PSL) can be preservative-treated to meet AWPA UC3B and UC4A standards, making it an option for deck framing. PSL consists of long veneer strands laid in parallel formation and bonded together with an adhesive to form the finished structural section. The least dimension of the strands must not exceed 6. CloustonAbstract: Measurement of the compressive strength of parallel strand lumber ! Engineered bamboo for structural applications. PSL is conducted on specimens of varying size with nominally identical mesostructure. The manufacture of SCL is standardized.

However, while SCL is included in the NDS, design values are provided by the manufacturers. For use of parallel-strand lumber as compression members a value of c = 0. Structural composite lumber - such as laminated veneer lumber (LVL), laminated strand lumber (LSL) and parallel strand lumber (PSL) - is used for support beams, window and door headers, and wall. Structural Composite Lumber (SCL) is the term used to describe a family of engineered wood products used for structural applications. When factoring in load requirements, member size and costs, deciding on the best solution can be a daunting process. Made from the same material as natural timbers, engineered timbers can be customized to allow for a cost effective beam with an increased structural load and longer spans.

OSB or particle boar but with a very engaging look). LVL is produced by bonding thin wood veneers, with the grain of the veneers parallel to the long direction. LVLs are available in 1¾-inch widths x 5½- to 24-inch depths and up to 60-foot lengths. Includes: wood foundations, framing, sheathing, and decking using lumber , timber, and engineered wood products.

Unmatched insight into opportunity. Intelligent Leads with Material Demand is a unique, entirely new way to bring relevant projects into focus.

The brand Parallam is an engineered wood product made from parallel veneer strands and adhesive bonding. Parallams can be used for for beams, headers and columns. Parallam is manufactured by Weyerhaeuser and is the only parallel strand lumber available in the USA.

Douglas Fir is the major species for lumber produced in the West, with more volume shipped than any other species.
