What is engineered lumber?
Engineered lumber products are fabricated wood pieces used to improve upon the normal capabilities of construction lumber. These products are composed of wood particles (veneer, wood chips, oriented strands, wafers, laminated dimensional lumber, and combinations Thereof) bonded by long-lasting adhesives to ensure the structural integrity. Engineered lumber is available in both structural and architectural (appearance) grades that maintain physical uniformity and longevity.
I-Beams are strong, lightweight, "I" shaped engineered wood structural members that meet demanding performance standards. I-joists are comprised of top and bottom flanges, which resist bending, united with webs, which provide outstanding shear resistance. The flange material is typically laminated veneer lumber (LVL) or solid sawn lumber, and the web is made with plywood or OSB. The robust combination of structural characteristics results in a versatile, economical framing member that is easy to install in residential and light commercial projects.
