Generally, you can find LVL beams in a 4-foot increments starting at 24 feet and going up to 44 feet long, with special customize size up to 60 feet. LVL beam width should be 1/4 to 1/3 beam depth.įor example what size lvl beam for a 20 foot span, as per general thumb rule, for a 20 foot span, size of LVL beam or GLULAM should be (20×12)÷20 = 12 inches deep and width of LVL beam = 12÷ 4 = 3″, which is nearly equal as 3-1/2 inches or 2ply wide, thus you need something like a 12″ thick or 3-1/2″× 11-7/8″ size of LVL beam to span up to 20 feet.Īn LVL beam can span up to 60 feet due to its strength and is much stronger than traditional lumber. For example: A 20 foot long LVL beam should be 12 inches deep (20×12) ÷20 = 12 inches).īeam depths are typically 5-1/2 inches, 7-1/4 inches, 9-1/4 inches, 11-1/4 inches, 11-7/8 inches, 14 inches, 16 inches, 18 inches and 20 inches. LVL beam calculator:- To calculate the LVL beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span in inches by 20. You can use LVL beam calculator to find required size of LVL beam. Beam width should be 1/4 to 1/3 beam depth. The width can be increased by laminating in multiples of 1-3/4 inches or 40mm. Design a beam width based on the fact that the typical width of an LVL beam is 1-3/4 inches to 3-1/2 inches. What is laminated veneer lumber (LVL) that will help you in better understanding and to figure out or estimate of LVL beam size and their depth. For example: A 20 foot long LVL beam should be 12 inches deep (20×12) ÷20 = 12 inches). To calculate the size of LVL (laminated veneer lumber) beam you need, calculate LVL beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span in inches by 20 and width of a LVL beam is 1/3 or 1/ 4 of its depth. How do I determine what size LVL beam I need? More than 60 Feet there is difficulty in transportation and handling. It can be customized according to your requirement. Generally you can find LVL beams in a 4-foot increments. LVL beam length:- LVL beam length are generally available in 24, 28, 32, 36, 40 and 44 feet with special order up to 60 Feet. LVL offer several advantages over technical milled lumber, it is made in factory under control specification and it is more stronger straighter and more uniform in size. LVL has a “maximum allowable bending stress” of 2,800 or 3,000 psi. Because of the wood’s dimensional stability, inspection times are often reduced, too. Use an LVL beam to eliminate twisting and splitting for quiet floors. It is a straight, enough strong wood that fights warping and shrinking, providing great stability for your projects. LVL beam is generally made of thin sheets of wood which are sandwiched and bound with super stronger glue. It is typically used for headers, beams, rim board, and edge-forming material. LVL beam (Laminated veneer lumber) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. How much does it cost to install a LVL beam.
