How strong is LVL lumber?
LVL is typically rated by the manufacturer for elastic modulus and allowable bending stress. Common elastic moduli are 12 GPa (1,700,000 psi); 13 GPa (1,900,000 psi); and 14 GPa (2,000,000 psi); and common allowable bending stress values are 19 MPa (2,800 psi); and 21 MPa (3,000 psi).Click to see full answer.

Similarly, you may ask, how much stronger is LVL than lumber?LVL has a “maximum allowable bending stress” of 2,800 or 3,000 psi. And according to this source, most wood has a maximum bending stress of about half that. So, yes. LVLs will bear more weight than the same size wood beam.One may also ask, how far can you span a LVL beam? Measure your total span between members and ensure that it is not greater than 60 feet. Because of transport limitations, the maximum standard length for manufactured beams is sixty feet. Keeping this in consideration, is LVL stronger than steel? In fact, LVL beams are on average 50% stiffer, 2 to 3 times stronger and have more density than the sawn timber from which they’re manufactured. Steel – being a manufactured product – has higher strength and stiffness properties compared to LVL but it is also almost 12 times heavier.How much weight can a LVL beam hold?Note: a single 2×6 will support 347 pounds per lineal foot of beam. Therefore, a double 2×6 carries 2 x 347 = 694 pounds per lineal foot. The required E-value does not change when you double the 2×6 because as you double the allowable load, you are doubling the thickness of the beam.
