LP Solidstart LSL

LP® SolidStart® LSL installs like traditional lumber, but surpasses it in strength and consistency. It’s strong, straight and ideal for a variety of applications. Long lengths and uniform dimensions reduce jobsite waste and low moisture content reduces shrinkage.

Fewer pieces means less time on the job site and less waste.


Use for floor beams, door and window headers, roof and wall framing, rim board, stair stringers and sill plates.
