Parallel strand lumber
Engineered wood products and an introduction to timber structural systems, published by the Structural Timber Association, defines parallel strand lumber (PSL) as: ‘…a structural member made by cutting long thin strands (typically 3.2mm thick, 20mm wide and up to 3.0m long) from timber veneers. The strands are oriented so that they are essentially parallel to the longitudinal axis of the section before being coated with adhesive and fed into a continuous press and microwave-cured. PSL is used in similar applications to LVL (laminated veneer lumber).’
