How It's Made

LP® SolidStart® I-Joists feature an advanced design and tough build for superior performance:

  • Combines laminated veneer lumber (LVL) or finger-jointed sawn wood flanges with a web of oriented strand board (OSB) to produce an I-shaped structural member.
  • Both materials work together to resist deflection, bending stresses and shear.
  • LVL and MSR lumber flanges up to 3-1/2˝ wide for greater stability.
