Laminated strand lumber

Engineered wood product developed in the 1980s in which wood strands are glued together and pressed into forms using steam injection. The strength and stability of LSL falls between that of conventional lumber and laminated veneer lumber (LVL).

Commercial SCL products include laminated veneer lumber (LVL), parallel strand lumber (PSL), and laminated strand lumber (LSL).
SCL materials tested included laminated veneer lumber (LVL), parallel strand lumber (PSL), and laminated strand lumber (LSL).
Tour participants were shown a new laminated strand lumber product using low-grade northern hardwoods, full-scale test apparatus for engineering earth-quake-ready wall systems, wood-thermoplastic extrusion machinery, visual analysis equipment, and other destructive and nondestructive testing technology.
This study investigated the effects of fire retardant chemical treatment on the physical and mechanical properties of commercial laminated strand lumber (LSL).
Laminated strand lumber (LSL) was introduced to the residential and commercial construction market in 1992 as an alternative material to conventional solid lumber.
The American Society for Testing and Materials notched wood shear block specimen is revisited for use with laminated strand lumber. Shear block tests on fully oriented and randomly oriented panels were conducted to determine shear strength in each of the orthotropic planes.
In a study on the strength of bolted connections in laminated strand lumber, the problem of adequately describing the shear behavior arose again since the shear strength plays an important role in brittle failure modes.

This rule would affect new and existing plants that make plywood, veneer, particleboard, OSB, hardboard, fiberboard, MDF, laminated strand lumber, LVL, wood I-joists, and glulam beams, and that are major sources of hazardous air pollutants, i.e., have the potential to emit at least 10 tons per year of any single HAP and 25 tons per year of any combination of HAPs.
In addition, the survey data suggested that large firms were more likely than small firms to try new substitute products, particularly finger-jointed lumber, structural insulated panels, and LVL, as well as newer engineered wood products such as parallel strand lumber and laminated strand lumber.
An exploratory study was conducted to establish toughness properties for several structural composite lumber (SCL) materials including laminated veneer lumber (LVL), parallel strand lumber (PSL), and laminated strand lumber (LSL).
Materials involved in the study included laminated strand lumber (LSL) and laminated veneer lumber (LVL).
