Weyerhaeuser’s TimberStrand Laminated Strand Lumber

Weyerhaeuser’s TimberStrand® Laminated Strand Lumber (LSL) manufacturing process can convert up to 75% of a log into high-performing engineered lumber. This process uses small-diameter, plentiful trees that are not strong or straight enough to be of structural value as conventional sawn lumber products. The wood is cut into thin strands and then glued together in a proprietary steam-injection process.
