What is laminated Strand Lumber made of?

Another question is: What purpose does laminated Strand Lumber serve?

Laminate veneer lumber (LVL), is an engineered wood product made from multiple layers of thin wood and attached with adhesives. It is used primarily for beams, headers, rimboard, edge-forming material, and beams.

Is LVL more durable than wood? Yes, most likely. LVL, or laminated veneer lumber, is made from, you guessed, thin wood veneers that are glued together much like plywood. LVL allows for a maximum allowable bending stressa at 2,800 or 3,000 PSI.

Also, was it LSL or LVL that is stronger?

LSL beams are typically cheaper than other engineered wood beams. LSL beams are able to penetrate larger areas than other engineered wood beam options due to their high allowable shear strength. LSL beams are not as strong or as strong as LVL and PSL beams but they are cheaper and can be used for shorter spans.

What's the difference between LVL & PSL?

Headers and beams, valley rafters, scaffold planking and the flange material used in prefabricated wood Ijoists are all popular LVL applications. PSL is made from veneers that have been cut into long strands and then bonded with an adhesive to create the final structural section.
