![]() If beam span is 20 feet in length, then their depth = (20 × 12) ÷ 20 = approx 12 inches and width is 12/3 = approx 4″. Beam width should be 1/4 to 1/3 beam depth.ĭesign a beam depth based on the rule of thumb for estimating the depth of manufactured beams which is to divide the span by 20.Īs 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. The width can be increased by laminating in multiples of 1 3/4 inches or 40mm. What size lvl beam do i need to span 20 feetĭesign a beam width based on the fact that the typical width of an LVL beam is 1 3/4 inches. The depth of the LVL (Laminated veneer lumber) is range from 5-1/2 to 23-7/8 inches. More than 60 Feet there is difficulty in transportation and handling. It can be customised according to your requirement. LVL length are generally available in 24, 28, 32, 36, 40 and 44 feet with special order upto 60 Feet. It comes in 1ply of thickness 1-3/4″, 2ply of 3-1/2″ thick, 3ply of 5-1/4″ thick and 4ply of 7″ thick. LVL beam standard thickness are ranging from 1 3/4 inches to 7 inches. LVL beam depth are typically 5 1/2 inches to 24″, it comes in 7 1/4 inches, 9 1/4 inches, 9 1/2 inches, 11 1/4 inches, 11 7/8 inches, 14 inches, 16 inches, 18 inches, 18 3/4 inches, 20 inches and 23 7/8 inches. LVL sizes may vary according to manufacturer but lvl standard thickness are 1 3/4 inches to 3 1/2 inches. ![]() What size lvl beam do i need to span 20 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. LVL is a straight, enough strong wood that fights warping and shrinking, providing great stability for your projects. LVL is product of recent innovation they are result of new technology and economic pressure to make use of new wood species and smaller trees that cannot be used to make solid Lumber. The American wood Council National design specification for wood, lvl is type of structural composite lumber comparable to glued laminated timber (glulam). It is available in a wide range of lengths, widths and thicknesses. It is typically used for boards of all kinds, for headers, beam rim boards, skateboards, as well as beams, trusses, edge forming materials and more. It is a high-strength structural engineered wood product of recent innovation and one of the most widely used kinds of lumber in construction projects in. Laminated veneer lumberor LVL is much look like plywood, generally made of thin sheets of wood which are sandwiched and bound with super stronger glue.
