Laminated Veneer Lumber: also known as LVL is the most widely used of the structural composite lumber products. It is produced by bonding thin wood veneers together in a large billet so that the grain of all veneers is parallel to the long direction. The LVL billet is then sawn to desired dimensions depending on the construction application. Some of the products many uses are for headers and beams, hip and valley rafters, scaffold planking, and the flange material for prefabricated wood I-joists.
