LP I-Joists
I-Joist Products
LP® SolidStart® I-Joists start straight and stay straight. They’re more uniform in strength, stiffness and size than solid sawn lumber and are less likely to warp, shrink, twist, split or crown. They’re light in weight and come in longer lengths and deeper depths so floors can be designed with fewer pieces, saving installation and material costs.

LP SolidStart LVL is ideal for beams and other primary load carrying applications. It can carry more load than solid sawn beams, so an average floor requires fewer beams overall. And, unlike traditional lumber beams, LP SolidStart LVL is available in custom lengths and widths, as well as three grades.
