LVL vs OSB

Natural Material · grade comparison

LVL and OSB are both natural material grades. LVL is the stronger of the two: tensile strength 42 MPa (6.09 ksi) against 12 MPa (1.74 ksi) for OSB, about 3.5 times as much. In exchange, OSB is the more ductile: elongation 1% versus 0.8% for LVL. LVL is lighter (0.55 g/cm³ vs 0.64 g/cm³ for OSB) and LVL is stiffer (13.8 GPa vs 3.5 GPa).

LVLChoose it when strength drives the design, or when weight is the constraint.

OSBChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

LVL vs OSB — frequently asked

Is LVL stronger than OSB?

Yes. LVL has a typical tensile strength of 42 MPa (6.09 ksi) against 12 MPa (1.74 ksi) for OSB — about 3.5 times as much.

Which is cheaper, LVL or OSB?

Both sit in the same relative cost tier ($, budget); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose LVL over OSB?

Pick LVL when strength drives the design, or when weight is the constraint. Pick OSB when the part is bent, formed or impact-loaded, or when the part sees heat.
