Features. LVL is stronger and more stable with a higher strength-to-weight ratio than conventional solid sawn lumber. Multiple pieces (typically used in pairs) can be fastened together to obtain greater thicknesses, resulting in greater strength to carry/support heavier loads. E Value (Modulus of Elasticity) = 1.9E or better.A 2×12 with an E of 800,000 psi and Fb of 790 psi also works, since it can span 15 feet and 10 inches.

A 30' beam easily weighs upwards of 500 lbs and would take a professional crew and some serious structural supports to install. For Joe and Kasey to span the length of their ceiling with real wood would be functionally impossible.Steel Beam Span Rule of Thumb. The general rule of thumb to calculate the depth of a beam is to convert the span to inches and divide by 20. So, a 30-foot span is (30×12) 360 inches, divided by 20 (360÷20) is 18 inches deep. The beam's width would be 1/3 to 1/2 its depth, so between 6" and 9" in this example.As per LVL span rule of thumb, the depth of the LVL beam should be 1/20th of span in inches and their width is 1/3 to 1/4 of the depth. If beam span is 18 feet in length, then their depth = (18 × 12) ÷ 20 = approx 11 inches and width is 11/3 = approx 4″. So, you would need something like 3-1/2″ × 11-1/4″ size of LVL beam for a 18 foot ...
