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.
