Our TimberStrand® LSL Beam is designed to reduce installation time and provide a one-piece solution for a variety of residential applications in floors and roofs. Now you can drill larger holes, up to a 4 5/8″ in our 14″ beam, without worrying about its structural integrity. Because they’re strong and stable they help reduce jobsite material and labor costs by allowing contractors to go through instead of around them. The TimberStrand LSL beam is competitively priced to provide an affordable engineered lumber option.
