The LVL billet is then sawn to desired dimensions depending on the end use application. LVL is made of dried and graded wood veneer which is coated with a waterproof phenol-formaldehyde resin adhesive, assembled in an arranged pattern, and formed into billets by curing in a heated press. LVL can also been used in roadway sign posts and as truck bed decking. Common applications of LVL in construction include headers and beams, hip and valley rafters, scaffold planking, and the flange material for prefabricated wood I-joists. LVL is used primarily as structural framing for residential and commercial construction. LVL is commonly fabricated using wood species such as Douglas fir, Larch, Southern yellow pine and Poplar. The manufacturing process of LVL enables large members to be made from relatively small trees, providing efficient utilization of forest resources. LVL is the most widely used structural composite lumber (SCL) product and provides attributes such as high strength, high stiffness and dimensional stability.
