Parallel-strand lumber (PSL) is a form of engineered wood made from parallel wood strands bonded together with adhesive. It is used for beams, headers, columns, and posts, among other uses.

Use beams, headers, and columns made from Parallam PSL and open up a whole new world of design options for the interior of a home. Create long, clear spans and support heavy loads, whether inside or out in the elements.

PSL is made from strands bonding together in a continuous press using waterproof adhesives with a phenol-formaldehyde base. It can made using waste materials from plywood and LVL production, with species commonly including Douglas-fir, pine and western hemlock, among others. PSL exhibits a rich texture and retains numerous dark glue lines.

2023年5月31日 · Parallel strand lumber (PSL) is a type of engineered wood made from long, parallel strands of wood that are bonded together with adhesive. PSL is stronger and more dimensionally stable than solid wood, making it ideal for use in applications where strength and durability are important.

2025年1月1日 · Parallel Strand Lumber (PSL) is an engineered wood product gaining popularity for its unique combination of strength, stability, and eco-consciousness. This comprehensive guide explores everything you need to know about PSL, from its composition and manufacturing process to its diverse applications and advantages over other engineered wood options.

Parallam PSL (Parallel Strand Lumber) uses a process patented by MacMillan Bloedel to bond together thin strands of wood typically 4-8 feet long. PSL manufacturing involves little waste, as almost all parts of a log are used in the product.

Parallel Strand Lumber (PSL) provides attributes such as high strength, high stiffness and dimensional stability. The manufacturing process of OSL enables large members to be made from relatively small trees, providing efficient utilization of forest resources. In Canada, PSL is fabricated using Douglas fir.

Structural composite lumber (SCL), which includes laminated veneer lumber (LVL), parallel strand lumber (PSL), laminated strand lumber (LSL) and oriented strand lumber (OSL), 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 ...
