When building a house, you want strong, worry-free lumber that provides the ability to include high walls, abundant windows, and sophisticated building designs today. Whether working on a sophisticated or simple home, Weyerhaeuser’s engineered lumber provides the best support while resisting warping, splitting and shrinking, and supporting heavy loads. We offer LVL beams, Rim boards, and TJI I-Joists for your next project.

LVL Beams

Without the natural defects of lumber, LVL offers consistent and reliable strength for structural building applications. Because LVL is a manufactured product made under controlled specifications, LVL is less likely to warp, twist or bow.
