Which product is used for beams and is known as Laminated Strand Lumber?

Laminated Strand Lumber (LSL) is specifically designed for beams and is manufactured from strands of wood that are glued together in a specific arrangement to create a composite material. This product offers a high strength-to-weight ratio, making it suitable for various structural applications, including beams, headers, and other load-bearing components in construction.

LSL is often chosen for its excellent dimensional stability and resistance to warping, which is crucial in applications where consistent strength and performance are necessary. It is commonly used in residential and commercial structures, providing builders with reliable material that can span longer distances than traditional lumber.

While the other products listed, such as Glulams, LVL, and PSL, are all engineered wood products with specific attributes and uses, they do not correspond to the definition of Laminated Strand Lumber. Glulams are made by gluing together layers of lumber, LVL is manufactured from thin veneers, and PSL is made from long strands of wood. Each of these products serves distinct purposes in construction, but LSL stands out for its unique laminate construction that uses strands, thus fitting the definition provided in the question.
